Thanks, Bob. The nicads were missing and the compartment corroded when I
got it. I assumed a 9v battery was the backup, but obviously I was wrong!

Any help appreciated.

The K-500 was designed to use four rechargeable
AA NiCd batteries for memory backup. The scanner must remain connected
to a voltage source for several hours to keep the batteries charged.

Inspect the batteries once in a while to make sure they haven't
leaked. Another caveat is that plastic battery holder inside the radio
can crack due to pressure from the spring contacts. Mine cracked.
