I'm curious, does this unit utilize a Bias Cell?

I'm asking because I've noticed that there appears to be a Bias Cell Holder (battery holder) underneath this unit, and if so, what kind of battery needs to be installed, and would it hurt this radio to run it without that bias cell installed?

See picture below.
