Then the repeater will automatically stop working. You need to:

1. Check whether the power voltage is too low or too high. If yes, replace the DC power

supply or backup battery.

2. Check whether the power cord is loose or damaged. If yes, secure or replace the cord.

3. If you cannot solve the problem, contact your local dealer for technical support.

When the voltage falls within the normal range, the prompt message will disappear, and

the Alarm Indicator will go out.

Caution: If low voltage is detected when the repeater is powered by a backup battery,

you need to charge it with an external charger. Remove the battery from the

repeater before charging.
