Dead Battery Question

I do the calibration every time I disconnect the battery.
Just turn the ignition on after the battery has been connected so the dash lights illuminate (no engine start) for about 60 seconds. You may hear the DME hum and click. Then switch ignition off and remove key for 10 seconds - that's it. The DME calibration is now complete and there's no wait time to re-learn anything.

No issues with disconnecting the battery. I would even suggest it is a good thing to let everything reset every so often. Just make sure you have your radio code. If you don't a few people on this forum have a way to decode it from the radio serial number.

I have never heard about this before, I'll have to try it next time I disconnect the battery!
