How and When I use my 9500i's TrueLock...

[MEM-TEK]

Don't even get me started about that video, I wish they would just do the right thing and pull that, its a discredit to the GOL having that garbage and purposely skewed video out floating around.

Hi everyone,

I too have duplicated GOL's results shown in their video. This scenario occurs when locking out multiple door openers present in some shopping centers where the 9500i does NOT display all of the frequencies being detected. In my tests against shopping centers with two or more pairs of K band door openers, approximately 50% of the time my 9500i would produce a spinning GPS icon when I turned on my 24.15 K band transmitter and then drove back to the locked out area. One moment my 9500i would be happily alerting at full signal strength to my K band transmitter, and the next moment after entering the locked out GPS cell my 9500i instantly stop alerting and would happily twirl its GPS icon.

My personal rules of thumb when using TrueLock are as follows:

1. If X band isn't used in your area then merrily lock out every X band false which you encounter. Also, ignore further below where I mention precautions about 10.525 frequency.

2. If K band isn't used in your area then merrily lock out every K band false which you encounter. Also, ignore further below where I mention precautions about 24.15 frequency.

3. If both X and K are not used in your area then you can ignore everything which follows below.

4. If you don't get false alerts when driving by a false alert location when using Auto Sensitivity mode, then simply use Auto Sensitivity mode rather than using TrueLock to lock out the false alerts. I call Auto Sensitivity mode "Black Magic" mode since it is uncanny at how it ignores false alerts yet will alert to approaching police radar or instant-on radar further down the road. Auto Sensitivity or Black Magic mode is far more reliable than using TrueLock.

If X or K band police radar is used in your area, then you need to have a thorough understanding of how TrueLock works.

-- TrueLock does not record the signal strengths of the detected false radar sources when you lock out a false alert location.

-- The GPS cells are hexagonal shaped and are roughly 1 mile in diameter. When you lock out a GPS location then TrueLock will merrily lock out every other X or K band radar encountered while you are driving through that particular GPS cell.

-- The GPS cell locations are fixed and are based on an evenly spaced grid of cells which covers North America. When you lock out a false alert location, the radius of the locked out location is based on the center of the particular GPS cell which you are in rather than being based on the exact GPS location where you hit the TrueLock button.

5. Once you have driven at least 1 mile away from where you used TrueLock to lock out false radar sources, either power cycle your 9500i using its power button or, if radar isn't present, mark and then unmark your current location using the Mark Location button. Either method will commit the gathered TrueLock data to permanent memory.

6. Since the GPS cells are about 1 mile in diameter, you can safely lock out stand-alone store locations which have just a single pair of microwave door opener transmitters as long as Spec mode displays frequencies which are not really close to 24.15 K band or 10.525 X band police radar. If this stand-alone store location is fairly close to another set of door openers, be sure to drive away from the stand-alone store location in a direction so that you do not encounter any other door opener signals. Then commit the lockout info to memory using Step 5 once you are at least a mile away from the stand-alone store location.

7. Never lock out shopping center locations which have multiple pairs of door opener transmitters by pulling into the shopping center so that your 9500i sees all of the door openers! There is a very high likelihood that one or more of the transmitters will be transmitting right on or very close to either 10.525 or 24.15. My tests show that this occurs roughly 50% of the time. If the shopping center is set back far enough from the road such that only one or two of its door opener transmissions are picked up by your 9500i as you drive by the shopping center, then you can lock out just these door opener signals as long as Spec mode doesn't show any of them being on or really close to 10.525 or 24.15 frequencies and as long as Expert mode shows that you are detecting just one or two X band signals or one or two K band signals. Keep in mind what I said in Step 6 about then driving away from this locked out location in order to not encounter any other false sources before committing the data to memory using Step 5.

There you have it!

Great info and great recommendations! Every 9500i user should refer to your guidelines when using their TrueLock.

My question is, why drive a mile before you commit the lock-out to memory? Is this to ensure it isn't locking out any other signals that might have been present when you hit the button to lock out your signal?

I have a question for when I get my 9500i. X band isn't used in my area, but K band is and %90 of the door openers here use K band so my question is, is if you park really close to the door opener and use truelock will it make the store pretty much in ther center of the 'truelock circle' or should you just use truelock right when you pick it up like going down the road?
From what I understand, where ever you press truelock it saves that location and in a 1 mile hexagonal shaped area all X/K signals are locked out. I'm just kind of worried because just today when I drove out of the grocery store parking lot whitch was giving my Bel 795 a weak false K band signal, I turn right on to the main road and Bam, full K band alert and I see a cop car 1/4 mile down the road in the oppisite lane.
I can't help but wonder if the 9500i would have alerted me to that K signal or not because I know I would have locked out that specific store.
So where's the best location to use truelock in my situation where some cops here use K band? Do you think if I had the 9500i in expert mode it would have alerted multiple signals detected?

nals as long as Spec mode doesn't show any of them being on or really close to 10.525 or 24.15 frequencies and as long as Expert mode shows that you are detecting just one or two X band signals or one or two K band signals

Be aware that the 9500i cannot detect 2 sources with the same or close frequencies in X,K and Ka band in expert mode. It only will tell you that there is only one source but in reality there is 2. The true lock feature incorporates the technology used in expert mode when it comes to eliminating a source which is also flawed. It will only detect 2 X,k and Ka band sources when there frequencies are way apart.

***** WARNING ***** NEVER RELY TOO MUCH WITH THE 9500i's EXPERT MODE WHEN TRYING TO FIGURE OUT IF THERE IS ONE OR 2 SOURCES IN THE SAME BAND.

Sorry I forgot to explain the reason for this. The reason is that the info does NOT get stored unless you have first left the GPS lockout cell and then you either power cycle your 9500i or use the Mark Location button to temporarily mark a location and then un-mark it. Once outside of the GPS lockout cell, either power cycling or marking a location will make the 9500i commit the lockout data to memory.

Using TrueLock when you are really close to the door opener will not make that location the center of the truelock circle. The center of the truelock circle is the predefined center of the GPS cell which you currently are in when you use TrueLock.

Also, never lock out door openers when you are really close to them! It takes a lot of signal to oversaturate the 9500i's circuits to the point where it can't accurately determine the frequencies being detected. The problem is that I don't know how much signal is needed to oversaturate the 9500i's circuits (haven't tested that yet).

From what I understand, where ever you press truelock it saves that location and in a 1 mile hexagonal shaped area all X/K signals are locked out.

Best location is when you are driving along and have begun to detect the false sources. Never lock out locations where the false radar sources are right next to the road due to possible oversaturation, as mentioned above, when you pass by those door openers really close to the road. Of course, you could lock out those door openers once you have determined their frequencies and then turn around to head away from them and get out of the locked out cell in order to commit the data to memory. Thats the only safe way I can think of to deal with "pesky" door openers which are located right next to the road.

X2 on locking out falses on your driving rout. However in your case i would suggest the below.

I would switch to speck display after confirming the 1 false you want to lock out. Lock out the desired false signal close to the door false and once icon stops spinning (may need to drive a few feet from false) power down the 9500I then power it up. See video, all was within 1000ft: YouTube - 9500I True Lock . This will prevent the 9500i from searching for more signals after you lock out your desired one and will help keep the lock out area as small as possible.

Ideally if the false is not in the 24.135 to 24.165MHz range where most actual police radar is found that would be best.

Sounds like your in a High Risk scenario, so you will need to be the most careful. It would most likely alert to multiple frequency's detected but we cant be 100% sure. If you use speck display to see what your local LEO's use you will be able to lock out all the falses not in there same 30MHz block.
Personally without knowing the K band the LEO's are using i would only lock out falses where they don't sit near, at least 1/2 to 1mi away. Auto mode will work real well where you don't want to lock out.

...signals as long as Spec mode doesn't show any of them being on or really close to 10.525 or 24.15 frequencies and as long as Expert mode shows that you are detecting just one or two X band signals or one or two K band signals

Be aware that the 9500i cannot detect 2 sources with the same or close frequencies in X,K and Ka band in expert mode. It only will tell you that there is only one source but in reality there is 2. The true lock feature incorporates the technology used in expert mode when it comes to eliminating a source which is also flawed. It will only detect 2 X,k and Ka band sources when there frequencies are way apart.

***** WARNING ***** NEVER RELY TOO MUCH WITH THE 9500i's EXPERT MODE WHEN TRYING TO FIGURE OUT IF THERE IS ONE OR 2 SOURCES IN THE SAME BAND.

Very, very VERY true! Thats why you want to use both Expert mode, Spec mode, common sense, and only lock out locations at a distance from the false radar sources.

Isn't there 4 on X band and 2 on the rest?

[MEM-TEK]

Isn't there 4 on X band and 2 on the rest?

Yes. Unfortunately if any two or more signals have approximately the same strength, then it seems that those signals are merely displayed as one signal rather than as separate signals due to their inherently different frequencies. Its obviously not as good as the V1's "bogey counter" which seems to do a better job of truly telling you how many distinct radar sources (based on frequency) are actually present.
