Atom Series Installation and Operation Manual

6.5. Alarm LED

The AT-2200 is equipped with Auto Shutdown and Auto Turn-on

functions. Whenever an incorrect installation or power surge occurs, the

red alarm LED will blink. It will also temporarily stop functioning in order

to prevent interference and to protect the repeater from damage.

1. When an alarm situation occurs, the repeater will shut down the RF

function at the same time.

2. When the alarm goes off, please check if the distance between the

donor antenna and the repeater unit is too short. Please keep them

as far away from each other as you can. You will need at least 8

meters between these two devices to make them work normally.

3. After the alarm situation is eliminated, the repeater will

automatically turn itself on in 20 seconds. If the alarm status doesn’t

change by the third time this happens, the repeater will shut itself

down completely. After that you can replug the power cable of the

repeater to switch on the repeater again.
