The battery ensuresthat power to the sound system will remain on during directional changes,setting RESET options or when travelling over dirty track and switches.The self-recharging battery backup system is automatically turned on or offwhenever track power is turned on or off.

Should this happen, unplug the battery from theProtoSound® module (to prevent the battery from being run down) andcontact MTH for instructions on returning the tender for repair.REPLACING THE PROTOSOUNDS® BATTERYThe ProtoSound® battery (located in the tender body), is a special NiCad7-cell, 8.4v battery - NOT the 6-cell, 7.2v battery found in mostconvenience stores. The 6-cell NiCad is NOT recommended for use withProtoSound® applications. The battery is continually charged from thetrack when power is applied and should last for up to five years. Inaddition, the NiCad battery is a dry battery and should not leak or cause anydamage to your locomotive during its lifetime.If you notice that the sounds seem distorted or garbled at low voltages orbecome silent when power from the transformer is shut off, the battery maybe going bad.
