1___________________________________________OPERATING INSTRUCTIONS

1 Operating Instructions
The HSS has two modes of operation, MAIN and STANDBY.
MAIN mode is the normal operation of the MAIN repeater and STANDBY mode is
when the HSS has switched to the standby repeater. There are two front mounted
LEDS. If the main repeater is connected correctly to the HSS the GREEN PWR LED
signifies that the main repeater has no alarms or fault conditions. If an alarm or fault
condition arises in the main repeater the RED ALM LED will light up and the HSS
switches to STANDBY mode.
The HSS does not need to be actively powered for STANDBY mode so in the event
of complete power supply failure to the main repeater the HSS defaults to STANDBY
automatically. For continued operation the standby repeater should have a battery
backup system and/or separate power supply.
