Hi Ken,

I am sorry I was not clear on my first answer earlier.

No, the Eeprom is "not" a battery, but it is a memory chip, so removing the transmitter battery will not harm any programming that you have in your radio.

And yes, it is still recommended that you send your radio in for a check up every 3 to 5 years, so that it can be checked to make sure that it is tuned correctly and there are no other problems with it.

Again, I apologize if I mislead anyone with my original statement, we all do of course know that an Eeprom is not technically a battery.

I hope you find this information helpful. Should you have any further questions or concerns, please do not hesitate to contact us at 217-398-8970 for Support, 217-398-0007 for Service or via fax at 217-398-7721 or by email at [email protected].
