You may recall that well over a year ago I commented that my V995, once in a blue moon, would start up with an unusual full start-up sequence. This was caused by a momentary power issue which corrupted its firmware settings. I then mentioned that RD users should power up their RD's only after they have started their car, and power down their RD's before turning off their car.
Well, today I was fiddling with my newly installed Cobra 75 CB radio before heading to town. I decided to power up my 9500ci so that it could get its GPS lock while I was playing around with my new Cobra CB. After several minutes, I cranked up my car and drove to town to do some errands. My 9500ci's display didn't even flicker for a split second while I cranked up my car. On the way to my favorite deli, I noticed that I didn't a couple of the normal weak K band alerts which I usually get around town. I didn't think too much of it since it is a nice day and maybe the nearby grocery store had locked its automatic doors in the open position.
After eating my deli sandwich and reading the local paper, I headed up the road to do some grocery shopping. I immediately realized that my 9500ci wasn't alerting to K band at all as I drove through the parking lot and right by several K band door openers. I parked my car, powered off my 9500ci, and powered it back up. Still no K band alert! I went into programming mode and confirmed that, indeed, K band was turned on. Everything else about my 9500ci seemed to be working just fine -- audio, GPS, speed display, et cetera.
Finally, I decided to power off my 9500ci using my kill switch since I have it hard wired to continuous power. I then did a factory reset while powering it back up again. Voila! My 9500ci, after a couple of seconds, began to strongly alert to the grocery store's door openers. So, this now is the third time that my 9500ci's firmware settings have become corrupted after first powering it up and then starting my car. And this is why I miss the "standard" or "long" start-up sequence which previous Escort RD's have, since when the firmware settings get corrupted due to momentary power glitches then the long start-up sequence usually acts weird as well.
The moral of this story? Always power up your RD after you have started your car and after you have confirmed that your car's engine is idling smoothly. Always power off your RD before turning off the ignition since the act of turning off the ignition can create a voltage spike. And, finally, its worth it to buy a dirt cheap inline noise suppression filter off of eBay or from a local car stereo shop. I just bought one for around $10 including shipping. A quality noise suppression filter has a built-in capacitor and a built-in choke. Together, these simple devices attenuate noise by at least 30dB, the choke blocks voltage spikes, and the cap acts as a small battery which is capable of powering your RD for several milliseconds if there is a momentary voltage drop.
And the final moral of this story? I really wish Escort would put back the option for the long or full start-up sequence! It most likely would have given me a clue that something was amiss before I inadvertently discovered that my 9500ci wasn't alerting at all to K band radar (or maybe any other radar at all).
