The X-Band 50 series can operate with an AC or
DC power supply. If AC power is interrupted when
operating the repeater with an AC power supply,
power is automatically provided to the [BATTERY]
terminals. Battery will be automatically recharged
when AC power is restored.
In AC operation

connection to a domestic AC outlet.
• Extension cords should not be used unless
absolutely necessary. Using improper
extension cords could result in fire risk.

In DC operation
CAUTION: Voltages greater than 16 V DC
will damage the repeater. Check the source
voltage before connecting the power cable.

correctly connected.
• When connecting to the battery, keep in
order to connect the DC power cable to
the repeater first, then the positive (red)
