SUBJECT: BATTERY MEMORY BACKUP
                                                        

     Memory in either radio may be retained by installing a battery inside
     the unit. This feature would be useful when transporting the radio base
     to mobile, or when operating base. The AC supply can be shut off while
     retaining the single memory.
     
     Obtain and install a small 6V DC battery, apropriately secured and
     insulated, inside the radio. Wire as illustrated through a diode. 
     Current drain will be approximately 0.5mA with the main supply OFF.
