Hi Steve,
The error code 1 on the R-89 to R-94 CCC can be down to static discharge or a low battery.
You need to check out the battery voltage on the CCC battery B1 without any power to the jukebox. the battery voltage should be 3 volts.
Replace the battery if lower than 3 volts. Put the jukebox into Service and enter into programing mode, if the factory settings are ok push POPULAR key, key 2, key 5 and the POPULAR again.
Swith off and put back into service. you may have to clear the error log.
If the CCC returns back into the programing mode without putting in a code you will have to replace the CCC.
