How to Set Up & Configure your Radenso Pro M

Want to learn how to use your Radenso Pro M and how to set it up for where you drive? Let’s take a look at all the buttons and menu options of the Radenso Pro M.

Radenso did a great job of setting up the detector to be quiet out of the box with settings that are optimal for most drivers around North America. However, you may want to change things depending on where you drive or your own personal preferences.

The Radenso Pro M user manual does a great job explaining things. Let’s go into more detail here.

Radenso Pro M

Note: This guide is current as of firmware US22. As the detector gets updated, the settings may change and so I’ll keep this guide updated accordingly. You can always check for and download the latest Pro M firmware here. (To check which firmware version you currently have, press and hold the middle button while powering on your Pro M.)

Radenso Pro M Buttons

The three buttons on top let you control the detector and dive into the menu. The icons on top of the detector tell you what a short press and long press does for each button.

Pressing any of the top buttons during an alert will mute your detector.

Here’s the main functions of the top buttons.

  • Left:

    • Short Press: Settings Menu
    • Long Press: Power On/Off
  • Center

    • Short Press: Brightness adjustment
    • Long Press: Mute On / Off (mutes all X / K band signals until you unmute)
    • Long Press during a false alert: Lock out this false alert so the detector mutes it every time you drive by
  • Right

    • Short Press: Change the Sensitivity
    • Long Press: Create Manual User Mark so you get notified every time you pass by this same location. Long press again during a user mark alert to delete it.

The side buttons adjust the volume. They also let you change the different settings in the menu.

Radenso Pro M Settings

Press the left button to enter the settings menu.

Press the left button to cycle through the different top level options. 

The middle button changes to the next sub-option. The middle button also activates the last few options such as doing a factory reset or clearing all your lockouts.

The volume up and down buttons on the side let you change the actual settings.

The right button exits the menu.

Auto City

Sensitivity adjustments.

  • Highway: Full sensitivity at all speeds.
  • City: Reduced sensitivity at all speeds.
  • Auto City: Full sensitivity at high speeds, reduced sensitivity at low speeds.

Auto city speed limit

If you select Auto City, this option will be available.

The first option allows you to adjust the speed thresholds.

Example: 30 / 60

  • First Number: Low speed muting for X/K band. Below this speed, your Pro M will visually alert to X and K band signals, but will stay silent. Ka and Laser will visually and audibly alert.
  • Second Number: Below this speed, your detector will run in City mode at reduced sensitivity. Above this speed you’ll run in Highway mode at full sensitivity.

City Level

Next you can adjust the sensitivity for each band. This option is available if you select City or Auto City modes.

Example: X4, K2, Ka0

The number adjusts how aggressive the filter is, 0-9. Think of it as how strong the signal needs to get before you get alerted.

0 means no filtering and full sensitivity. 9 means the most filtering and the least sensitivity.

Be careful not to get these backwards! You’ll usually want more filtering (higher numbers) for X and K than on Ka. 😉

Display Mode

Information shown on screen when no alert is present.

  • Speed / Compass
  • Speed / Time
  • Speed / Voltage
  • Voltage
  • Time
  • Speed


Adjusts the units for speed and distance.

  • English: MPH and feet
  • Metrics: KPH and meters


Choose what and how the detector displays during an alert.

  • Freq: Shows the band, signal strength (1-9), and frequency
  • Bar: Shows the band and signal strength visually in bars, more bars for a stronger signal


Enables voice alerts and speaks the menu options.

  • On
  • Off

Auto Mute

Reduce the volume of an alert after eight seconds.

  • On
  • Off

Alert Tones

Here you can change and customize the alert tones for the different bands. There are 15 unique tones to choose from. This is useful if you don’t like the default alert tones, you want X and K band to sound different, etc.

  • X Tone
  • K Tone
  • Ka Tone
  • MD Tone (MultaRadar CD)
  • MT Tone (MultaRadar CT)
  • Gatso Tone
  • Laser Tone


When you pick up a previously locked out signal, you can have the detector give you a single beep to let you know it’s picking up a signal, but locking it out for you, or stay totally silent.

  • On 
  • Off 


Low speed muting of X and K band. (It’s similar to the low speed muting for City / Auto City modes, except this applies to all sensitivity modes, including Highway mode.)

  • Off
  • 5 – 130 mph in 5 mph increments


Enable or disable X band detection.

  • On
  • Off


Enable or disable K band detection or adjust the frequency range the detector scans for.

  • Off: Disable K band detection
  • Wide: 23.950 – 24.250 GHz (24.100 GHz ± 150 MHz)
  • Narrow: 24.010 – 24.190 GHz (24.100 GHz ± 90 MHz)
  • SNarrow: 24.085 – 24.185 GHz (24.135GHz ± 50 MHz)

K TS Rej

K Band Filter. The name means traffic sensor rejection, similar to TSR/TSF/TMF with other detectors, but the blind spot filter is also built in to this filter as well. The higher the filter, the more aggressive it is.

  • Off
  • Low
  • High


Enable or disable Ka band detection. If you select Ka Narrow, you open up additional options for Ka band segmentation. In the US, only 33.8, 34.7, and 35.5 are used.

  • Off
  • Wide: 33.4 GHz – 36.0 GHz
  • Narrow: Band segmentation. Each segment is ± 120 MHz.
    • Ka 33.8
    • Ka 34.3 
    • Ka 34.7
    • Ka 35.5

Ka Filter

This helps filter out false alerts on Ka Band.

  • On
  • Off 


Detection of 67ms Ka POP.

  • On
  • Off 


Enable or disable laser detection.

  • On
  • Off


Detection of the MultaRadar CT used in Chicago and NYC.

  • Off
  • Wide: Enable MRCT detection of frequencies used both in North America and the lower frequencies also used Europe.
  • Narrow: Enable MRCD detection of frequencies used in North America.

MultaRadar detection range and performance is other unaffected by the Wide / Narrow options.


Detection of the MultaRadar CD, used Alberta (Edmonton and surrounding areas), Maryland, & Washington D.C.

  • Off 

MR Filter

If you enable either MRCD or MRCT detection, the MultaRadar Filtering option will show up as an option. 

The MultaRadar Filter helps to filter out false alerts from other frequency modulated radar sources (like BSM radar) that aren’t also MultaRadar sources.

  • Off
  • Low
  • High: Most aggressive filter. This is what most people run and it’s the recommended setting.

Startup Sound

Enable or disable the startup sound, a three-beep jingle.

  • On
  • Off 

GPS Connect Announce

Enable or disable the announcement when a GPS signal is acquired.

  • On
  • Off 

GPS detection

Choose which types of fixed known locations you want the detector to alert to. These are alerted to using the GPS location, not radar or laser.

Press the middle button to switch between the different options.

  • Speed Cam

Vortex’s Personal Settings

There’s no one set of settings that are ideal for everyone. That’s why they give us the ability to change them. 😉

Here are the settings that I use myself. They are basically designed to quiet the detector down a bit more, disable X band since it isn’t in use up here, give me more information like the signal frequency, disable the manual user point alerts since I don’t use that feature, and stuff like that.

If you want different settings or you live in an area with the X band or MRCD/MRCT, for example, you should adjust your settings accordingly.

Additionally, I’m still experimenting with the different alert tones

Note: I’ve put a (*) in front of each setting that I’ve changed from the defaults.

    Hi Vortex, Thanks for this information on the Set Up of the Radenso Pro M.
    Question for you,
    I have updated to the latest version form the Radenso web site for the Pro M version US 14,
    But now when I check on the unit by way of holding down the center button before power on, It tells me I have US 16 instead. Can you advice why mine says v16 when their web page suggest the latest is v14?
    I will try to attach a picture for you in Facebook of mine so you can see that.
    Thank You Vortex.

    According to Jon at Radenso it is because the company has been crazy busy and has not had time to update the website. US16 appears to be the most recent.

    My name is Darrell Wilson,I never had a radar detector would the Radenso Pro M be a good one or should I wait and see what comes out? My email is [email protected].

    1. Oh it’s a great detector. I’d have no issue in picking one up today and enjoying it for years to come.

    So I do a lot of driving all of NY most in the city. I go to Ohio a lot to visit family. So I go through NJ PA. I can not decide between the R3 or the Pro M. Can you help.

      I was in the same predicament. Bought both and ran them side by side. Unless you need insane amounts of range. Go with the pro M, the blind spot filtering is far better. Has very good range as well but it doesn’t beat the R3 range. But the r3 goes off for a lot of cars blind spot monitors in my experience.

    I really like my Pro M (wish it had a mute on the power cord), but was not a fan of the suction cup mount.
    Also, found the mount release button a little difficult to activate. I added some stick-on material (glides for computer mouse trimmed to fit) to it so it is easier to release now.
    With a little cutting and filing I was able to adapt a suction cup mount for it that works very well.

    If you would like to see my mount, please provide instructions so I can forward the pictures and parts used.

    Thanks and keep up the good work!

    so why do you have the MRCD & MRCT off… I live in Chicago suburbs

    1. Please configure the detector in a way that is appropriate for where you drive.

    I turned on MRCD and MRCT because I sometimes travel through Chicago and Iowa. It definitely seems to have a lot more falses on those two in other areas. Would be cool if you could save custom configurations for different areas you travel.

    Bought a Pro-M a couple of months ago based on your testing and comments and I love it. The BSM filtering is, I believe, second to none, and definitely destroys my old Passport in that category. One thing that doesn’t get mentioned enough is how small and light this thing is. I mean we’re talking half the size and weight of some other detectors. Definitely a nice small footprint in your car.

    My drive is between Provo and Salt Lake City on 15. I get a lot of K alerts but they are always very brief and I’ve never seen a police car when it goes off. Do you think it would be safe to turn K band off until I make a longer trip?

    Thank you for your review – I bought a Pro M recently and it is great. Is it possible to tell the distance on the alerts when they go off? I haven’t programmed the Pro M and used it right out of the box…I am reading your information to see about making any changes. I do a lot of highway driving each morning and night for work and not really a lot of city travel – would you recommend that I change anything? Also looking for a less expensive radar detector for my wife – I’ll look on your site but would appreciate your recommendation. I really appreciate your work – I watched several of your videos and made my decision to buy the Pro M while contemplating the more expensive radar detectors out there. My wife said that I wanted to speed because I bought a detector. This is not why i bought it but to give me more information while driving. Thanks again for your work!

    1. There is no ability to measure distance itself from a detector based on a signal strength. A weak signal could be super far away with nothing between you and the radar gun, or it could be much closer but with a big hill and a bunch of trees between you and the radar gun. The radar detector can tell you how strong the received signal, but not how far away that signal is.

      If you’re new to the Pro M, I’d personally recommend sticking with the factory settings for now. They do a good job of setting it up for you out of the box. Once you get more familiar with it, you can start dialing it in further.

      If you’re looking for a less expensive detector, Radenso also makes the XP and SP which are more affordable than the Pro M. The Uniden DFR7 is a good budget choice too.

    I bought a pro m 10 months ago for use in Australia. while radar works well the laser detection against poliscan mobile cameras is nill… Company has no answers. My old beltronics magnum does a better job in laser detection than the Pro m… Very dissatisfied

    Thank you for this article! My Pro M sometimes shows MT when it beeps and I can’t figure out what radar it is picking up on/signaling. Any ideas on that?

    1. It’s alerting to MultaRadar CT. That can be triggered by actual MRCT photo radar sources, as well as things like certain door openers and vehicles with BSM’s.

    Just got a Pro M and I really appreciate these recommended settings! The only question I have is about X band. I live in Ohio (and sometimes travel to NJ) so I need to have this enabled. However, it seems like it is nearly constantly alerting (mainly 10.525).

    I currently have the filter set at X4 as you recommend above. Is there anything else I can do to quiet this down? I’m having a hard time discerning what might even be setting it off, particularly on the highway. Thanks in advance!

    I agree with Colib I’m also in Australia.
    The pro m does not give any warning for poliscan mobile cameras. And yes my old beltronic magnum that’s at least 5 years old does.

    I recently bought my new Radenso PRO-M based on its impressive reviews that I read, specially I was focused on the elimination of false alarms signals, that I read about this radar.
    My older and trusted 7.5 year old Escort Redline which had a very long range detection, it wasn’t able to eliminate the false signal from the proximity sensors technology on some new cars.
    I just made a 10 hours trip using my new PRO-M, expecting to be the best road trip experience, but it was exhausting, my new Radenso every time that I was overpassing a car or truck went into false K1, K2 ,K3 and K4 24.150 frequency alert.
    I did reset it and the issue continued.
    I stopped trusting my radar on my way back to home.
    I hope I didn’t made a wrong radar detector purchase decision.?

    I get a lot of Gatzo alerts if I turn it off. Will it alert as K band? MRCT a couple of times…
    When I run R7 I get none of those…just k alerts. Thanks.
