Hi everyone,Originally Posted by Esoterica
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!
