SD-170EX Series Operation Channel select / SCAN Your radio‟s channel can be selected by inner DIP-S/W or serial command inputted from external control system. To change channel by inner DIP-S/W (), you should open the upper cover and then look for the DIP-S/W() on the digital board of the bottom cover.
Scan modes Scanning is a programmable feature that allows you to monitor a number of channels. Channel scan Once the scan list has been established, initiate scan by serial commands. If a conversation is detected on any of the channels in the scan list, the radio will stop on that channel and you will be able to hear the conversation. At that time, busy channel data is sent to external equipment or device through serial command.
