16 OPTION UNITS SETTING ■ MB-106 carrying handle The optional MB-106 carrying handle is convenient when carrying the transceiver for DX' peditions, field operation, etc. q Attach the rubber feet with the supplied screws as shown below. Rubber feet w Attach the MB-106 to the left side of the transceiver as shown below. Carrying handle ■ Band voltage modification If you want to connect an external unit which can be controlled by the band voltage from [ACC] connector, the following modification is necessary. The band voltage appears on pin 5 of [ACC] connector after modification is completed. Performing this modification is the customer's re- sponsibility. Icom does not guarantee this modifi- cation's result. CAUTION: Disconnect the DC power cable from the transceiver before any work on the transceiver. • Band voltage generator circuit The below circuit is just for reference.
