Starting the Repeater
1. Turn the mains switch on (marked ’S’ in Figure 4-1).
2. Check the LED on the power supply unit (V). It must be lit with a
steady yellow light.

up is indicated as follows:
PWR
Yellow LED which is lit with a steady light after the mains is
switched on. Indicates present power.

for the next 5 - 10 seconds. After that, if no error is detected, the
LED is off.

on. Then, it flashes for less serious alarms (ERROR) and is lit with a
steady light for fatal alarms (CRITICAL).
OPER
Green LED which lights up approx. 15 seconds after the mains is
switched on. It shows, with a steady light, that the repeater is ready
for operation.

the alarm relays. A correct power up is indicated as follows:
OPER
Green LED which has the same indication as the green LED on the
CU board (see above).

alarms.
