In 2 weeks my X-50 has started 3 times in self cal.
What is the meaning of this, i.e.
1. Is this frequency considered normal,
2. What event or events trigger a self cal, and
3. At what point does the self cal become a service required?
Also I asked about modes and bands affected.
The reply seemed reasonable:
"It is good to hear from you! The Passport 8500 and 8500 X50 runs the self-calibration frequently. Most of the time, it will not show up on the display. When you see the display read "self cal", it is auto-correcting the range of frequencies the detector is tuned to receive. If it fails to correct itself the display will read "service required" to let you know it did not complete the self-calibration. If it does not show the "service required" message, it sounds like your Passport 8500 is good to go.
There are only three states that still use X-Band for traffic radar in any numbers: Ohio where we are, Indiana, and New Jersey where you are. Because X-Band has longer range than the other bands, increasing the range will only increase false alerts for our customers.
The Auto, City and Highway Modes affect X-Band only. You might want to use your Passport in the Highway mode for the best sensitivity on X-Band.
Thanks for your interest in Escort!
