Main power
Use an AC outlet capable of supplying AC 100-240V at 50 or 60Hz.
1
Insert the socket of the provided AC power cord into the AC IN jack at the rear of the repeater.
2
Insert the plug of the provided AC power cord into the AC outlet.
z
Backup power
For uninterrupted operation during power failures, a 13.8V rechargeable automotive type battery (55-Ah or
more recommended) may be connected to the BACKUP terminal posts on the rear panel. In the event of
an AC power outage, the automatic power control circuit will switch the repeater to the backup battery, and
operation will not be interrupted.
While operating from a battery or DC supply, the repeater requires approximately 14A at 13.8V during
transmit.
Always observe proper polarity when making DC connections.
z
Use a power source capable of supplying DC 13.8V and a current capacity of 14A or more.
z
Make sure to switch OFF the power of the external power source before connecting.
z
If the transmit power is set to “HI” (50W), the transmit power is automatically set to “MD” (20W) when operation is
switched to the backup power supply.
z
The repeater is not designed to charge depleted batteries, as their current requirements will be too great. Use of a
properly designed, regulated charging circuit is required.
1
Insert the connector of the provided DC power cord into the BACKUP jack at the rear of the repeater.
