    British Columbia, Canada Forest Service  Radio #  312


    This unit has a wooden case with the Transmit / Receive chassis and controls in the top half of the case and the batteries located in the bottom half.  Originally this unit would have had a front door that closed. The microphone, which is missing, would have hung on the inside of the door. The door would have closed and latched when one wanted it to be portable. 

    There are two unidentified two pin sockets mounted on the chassis which are not identified. They are not available for users use.

    Power Requirements:
    Power for the entire Radiophone is supplied from dry batteries. There are two groups of "A" and "B" Batteries which are described as "Normal Duty Batteries" and "Light weight batteries".  Two cables are provided, one for the normal-duty and one for the light weight batteries. Either set of batteries may be connected to the Radiophone by plugging the cable into the cable socket on the front of the radio. The later model variant’s of this radio have the battery cable(s) directly wired into the chassis.
