Remote ON/OFF Power Control: The SG-500 can be turned on/off remotely via a connector provided for
this purpose. To the left of the front panel PTT selection switch is a vertical 4-pin header. A jumper
comes installed across the top two pins, which are in series with the front-panel ON/OFF switch line. The
bottom two pins provide indicator output for a LED, and are in parallel with the front panel PWR LED.
SGC provides a Remote Control box for the amplifier that can be purchased separately (Cat. #52-88).
To install a custom remote on/off switch, remove the upper jumper and connect your switch leads in its
place using a push-on connector. Likewise, a remote LED can be connected to the lower two pins if
desired (LED ground connection on the lower pin). Leave the front panel on/off switch in the ON
position to enable your remote line in this configuration.
