What are you guys with RC-M have your units configured with?
I know the factory recommendation setting are from Manual, but I'm curious if you guys made any adjustments from using it daily.

I got ALP on mine too and I'm running with MRCD Narrow since I get those in DC metro area now.

thank you in advance.

I have a Pro-M not an RC-M, but they're very similar and I believe most of the options are the same.

One thing to consider changing from factory defaults is to change TSRej from "High" to "Low". User @DC Fluid posted some test results showing that "Low" has very little range penalty vs "off" but "high" takes a much more noticeable chunk out of K band range, and could be a difference maker vs instant-on situations or difficult terrain.

The downside of going with "Low" is that you may get some Honda/Acura BSM falses. But generally people haven't reported it being a big issue. I switched to "Low" and haven't looked back.

Change your alert tones, or at least play around with them a bit. If you get a tone scheme you're happy with it'll make for a more enjoyable experience.

I also cranked up the K City Level to 7 (default is 2 at least on the Pro M) because where I drive there are a lot of false K sources. Because of that more aggressive filtering in City mode, I knocked down my AutoCity speed limit to 45. (I think I'll go up to 50 at some point, but I need a bigger sample of encounters. Where I drive we have some 30mph zones where the traffic naturally flows at 40+, so nasty tickets are possible even at seemingly innocuous speeds)

I would definitely encourage you to play around with the settings. Factory defaults are fine, but there are so many options that you can likely find a configuration that fits your driving a little better.

I have both. The RC-M paired with ALP’s and multiple Pro-M’s.

What exactly are you asking? There’s lots of settings, you need to narrow it down a bit and maybe I can answer what it does and you can decide if it’ll work for you.

I agree about the alert tones. it's def different than what I'm used to with Escort.
I've changed them around a bit.

I'm getting a ton of false alerts on K band around here (Norther Virginia). I'm guessing it's BSM related.
I didn't think about adjusting the K band level. thanks for that suggestion. I've been running pretty much off of the default out of box settings for my first week now. I'll play around with it a bit.

we have some MRCD around in this area. I'm getting way too many false alerts on that. I did turn MRCD off on the rear radar. I found that not too useful.

thanks for the suggestion on K Level. I'll def try that out at different levels.

Glad to meet another RCM+ALP user. I do have a question.
a strange thing is happening with my ALP.
I the both f & r laser turned on. with laser voice announcement on "Yes".
JTK is currently set at 4 sec.
Parking is turned off in the setting.

so far on about a week's worth of use, I still have not run into LIDAR situation on the road yet.

I went through a carwash yesterday and the laser alert came on.
no directional indicator. and no laser type announcement.
the alert lasted definitely longer than 4 sec.

so my questions are:

1. Do we get directional alerts on lasers too?
2. when automatic JTK is kicks in, are there any indicators on the RC-M display?
3. if it's parking feature is tripped in ALP, does it say "parking" or "laser"?
4. have you seen LIDAR detection instances where ALP does not identify the type of gun?

thank you in advance.

D.J. the TSRej = BSM filtering on the RC-M. If you are getting too many falses set it to High. I tried various settings but always wind up on high. If you found yourself on an open stretch of highway with little or no traffic you could turn it to low or off. I don't have MRCD in my area so I have it off, not sure how that effects the BSM falsing

Combine that with the AutoCity mode & Low speed muting and the lock out the door openers along your normal routes. You should find the detector to be very quiet with the exception of a handful of specific year/makes of Mazdas, Cadillacs and Buicks.

So when K goes off at that point, Pay Attention!

Copy that Edward. TSRej High.
Thanks so much for sharing your experience.
I've used various models of Escort for a couple of decades. I know all their nuances.
still trying to figure and feel out RCM+ALP combo...

Ok.
A few car washes do use a type of Lidar, or electric eye to make sure the arms... especially “Touchless Car washes”.... don’t smack into your car, or go further than they need to, too save water.

If it false’s like that, it’s probably a fail safe to alert and not know.... than no alert at all. I’ve never personally had it happen, but that’s quite possible. Why it’s going in longer than 4 seconds.... I really don’t know.

Direction arrows?
Yes. Just like the RC-M when your hit by radar.... Lidar operates the same way. I’ve also added the ALP LED light to my system.

I’ve never had the set up not given me the announcement of what gun I’m hit with. I have a Lidar tester, and it has 4 or 5 different types of Lidar guns in it. The only one it never announced or recognized was the Tru Speed S..... but then again none of my other detectors alerted to it.... so I’m guessing it’s the tester and not the ALP’s or my other detectors.

It’s the TMG handheld one. If you haven’t got one, they’re handy to have to check your heads. You can see if @Jag42 has some available for sale.

For the parking sensors.
I’ve never looked at the display. I’ve had them off for quite a while. The LED would flash red and increase flashing more rapidly the closer I got. I also relied on the audible tone, rather than what the display did.

If you want, I can easily check it out if you’d like. Just to be sure.


Don’t run TSRej on high unless your sure your not going to face K band.

Here’s the deal about TSRej.

It stands for Traffic Sensor Rejection.... but it’s more of a 2nd K band filter. It’s active all the time that k band is on. If your in A/C mode..... your relying on the K band filter settings while your under your upper threshold speed. The TSRej is active as well.

When you break that upper threshold speed, the RC-M jumps to HWY sensitivity. The thing is, the TSRej is still on.

Your better off upping the K band filter while in city mode, or under the upper threshold of A/C , than to increase the TSRej level to high. Especially if there’s a chance if I/O K band on the highway.

So.... don’t run TSRej on High. It doesn’t stop filtering. Running low is not as intrusive.

@DCFluid just tested this on the Pro-M recently. They’re the same.

How much range is lost due to the TSRej settings.

I thought that (auto) city just attenuates the signal. It that what you mean by filter?

In auto city mode?

It allows you to automatically go between the city settings and hwy setting at what ever speed you’d like.

If you go to hwy, you’ll notice you no longer have X0/K0/Ka0 adjustments.

Those are the individual filter controls for each band.
0= next to no filtering
9= max filtering.

Also remember, even if your running you K band filter at 0.... it’s only at around 60% of the detection range of Highway mode.

In AutoCity mode you get to choose at what speed you want maximum highway sensitivity and ignore the filter settings of X/K/Ka.
That’s what AutoCity does. It changes it from a city level and filter settings to maximum sensitivity at what ever speed you choose.

Escort does this in Auto Mode. At about 50 mph, it increased the sensitivity for you. That’s why there’s no city setting on the escorts. You can’t change it in the escort detectors, but you can on the Radenso’s.

On the Uniden’s, you have to physically switch it between city and highway.

On the Radenso’s you’ll see 2 different speed settings.

The other one is further in the menu. It’s called “Speed Setting For Radar Alert”

That is used for blocking radar alerts under a certain speed, of your choice, when your in city or Highway mode. That’s because you do not have an upper and lower threshold in those modes like you do in AutoCity.

I did a test once in city mode against k band.
0 gave me about 8000 feet.
9 chopped it down to around 1500 feet.

So yes. City mode does knock around 40% iff the overall sensitivity, but the individual filters knocks it down even more.

Pile TSRej knocks it down more than that.

Years ago I did test it. In city mode and K band filter at zero.
I think it was on FW US4

TSRej on low, I lost 100’
TSRej on high, I lost another 163’ for a total of 263’.

It seems that might if changed and the TSRej setting really kills your K band detection.
@DC Fluid just did a recent test. He’d be the best to tell you how much there was between low and high. It’s here someplace.

@DC Fluid That test was amazing, thank you for all of the work!! For me, it boils down to how much BSM falsing I am comfortable with in my daily driver. I run a Uniden R3 in one of my cars and I ignore K band most of the time because of how chatty it is to BSM falsing, which led me to the RC-M for my other car.

I love that these detectors have settings so everyone can adjust to their own preferences and situations. I'm also very thankful everyone here does the testing so we can all make informed decisions in how we choose those settings.

thanks for sharing the experience. we can't never get enough info, you know. :)
your explanation makes sense about TSRej.
I'll have to play around with TSRej and K band settings.

Hey OP, check out this cheat sheet we have. Pretty nifty. Updated about 2 months ago so there should be no variances. Take note of specialized settings for certain parts of US, CAN and AU/NZ. Cheers.
Min Diesel,
Excellent information.
May I make a small suggestion on the cheat sheet?

for the ALP firmware update section:
if the current f/w version is already the latest, nothing will be displayed on RC-M screen to indicate any f/w update activities.
the config update also would happen so fast, the RC-M appears to be booting up normally as if ALP f/w update did not work.

I got completely confused and puzzled when I tried to update ALP for the first time.
had to do a bunch of research before learning that nothing happens (no acknowledgements) when the ALP f/w is already good to go.
