Notes:

$ Priority is given to the power supplied from the AC adaptor when

 

both a battery pack and AC adaptor have been connected.

 

$ When the AC adaptor is used, the low battery warning may appear

 

depending on the BATT.SELECT menu setting. If this happens, it

 

is recommended that the Ni-Cd12V setting be used for

 

BATT.SELECT.

 

$ When the AC adaptor is used, the AC adaptor’s power must be

 

turned on before the unit’s POWER switch is set to the ON

 

position. If the POWER switch is set to ON first, the unit may

 

malfunction since the AC adaptor’s output voltage increases

 

slowly after the power has been turned on.
