I have one of these and the low battery indicator keeps going off even
though the batteries are fine. Any odeas. I know this is an older unit,
but it works well as one of my many scanners.

Thanks...

nicads or standard cells?
a nicad stack will be a lower voltage than a stack of dry cells
could this be it?
else, get a variable psu, connect it where the battery clips are and vary
the voltage to find its trip value.
don't know of a standard fault about this, but i know the charging circuit
can go iffy.

Are you using NiCads? NiCads are only 1.2 vdc, where Alkalines are 1.5 vdc,
per cell. Multiply the difference by four cells, and brand new, fully
charged NiCads would produce 4.8 vdc, where Alkalines would produce 6 vdc.
So NiCads would look 1.2 vdc low, right from the start.

That is why a lot of the newer scanners have two different battery trays,
depending on what type of cells you use. They compensate for the
difference.

According to the PRO-34 manual, you can use alkaline or nickel-cadmium
batteries. The radio has a built in circuit for charging NiCads.

Newer scanners have two battery holders to prevent inadvertent charging of
alkalines. One holder does not connect to the charging circuit while the
other does. That's the only difference and there is no voltage compensation.

Check for dirty / poor contacts in the battery pack
