User Guide Version 1.2.5
The CommBat provides talk circuit battery for use on copper wire pairs. Headsets or butt sets are used at each end to complete the talk circuit.
The CommBat applies up to 30VDC to the pair while limiting the maximum current to 10mA. The design prevents excessive current on short loops and automatically applies additional voltage to maintain adequate current for longer loops.
Connection
The CommBat connects to one side of the headset/butt set and one wire of the pair on one end of the loop. The other side of the headset/butt set connects to the other wire of the pair. The headset/butt set connects directly to the pair at the far end. Refer to the diagram below.
Operation
Press the On/Off button on the top of the CommBat until the LED comes on and release. The LED will start to flash approximately once per second. Press and hold the On/Off button until the LED goes off to turn the power off. The LED will stop flashing.
Battery Test
Press the On/Off button momentarily while the CommBat is on. The LED will flash rapidly if the battery charge is low. The LED will light for approximately two seconds if the battery charge is OK. The CommBat has less than 8 hours of operating time left when the battery test indicates a low condition.
Battery Service
Remove the battery cover on the rear of the CommBat and install four AA batteries. Batteries should be removed when the CommBat will not but used for an extended period. Batteries may leak and damage the CommBat.
Operational life may be extended by using long-life batteries.
