[Wswss] old fm radio question

[Len Gwinn]

Have an old Icom IC-45 fm radio---440 mhz.  It works BUT keep-alive battery gone.

Anyone know ""where the battery is located in the radio ??""

and

""What is the voltage of the battery supposed to be ??""

Lost manuel so in a bit of a hard place.

Thanks in advance.
