Board)
Priority
The Remote Station RB-500 usually has higher priority than the FS-1503. This means that opera-
tion of the FS-1503 is disabled when the handset of the RB-500 is picked up. The indication
“REM” appears on the FS-1503 display when the remote station is in operation and the PTT
switch on the microphone of the FS-1503 is inoperative.
Communication on 2182 kHz
When 2182 kHz is selected on the FS-1503, the FS-1503 takes priority.
2.3 Intercom
The intercom provides communications between the FS-1503 and the RB-500 Remote Station
(option). They must be wire-connected. When intercom mode is in use, there is no radio trans-
mission.
