The LPOD-R does not contain a Power On/Off switch. It is powered ON by connecting the J3 |
POWER IN connector to the appropriate prime power source. The Mute or Transmit status of
the unit will automatically come up in the last stored state (factory default = Transmit on, not

2.4.1 Monitoring LPOD-R Operation with the LED Indicator (PS .5 ONLY)
The LPOD-R PS .5 features a multi-color Light-Emitting Diode (LED) Indicator. Figure 2-8 shows
the location of this feature, on the signal output side of the LPOD-R PS .5 housing, next to the
ground lug. This LED provides you with visual cues to the operational status and LO setting for
the system.
