Fix
Replace the front panel door plate by attaching the ribbon cable lead and fixing with the door Hinges.
Attach all plugs ensuring they fit squarely into the connectors.
Do not connect battery until the Master has been powered up on mains
.
Powering UP
Carefully check the outstation wiring then apply AC power to each VoCALL Compact master unit- DO
NOT commission on batteries as the power supply has a large reservoir capacitor which may rupture
the battery fuse if the AC is not present when powering up the system. Once the system is powered, the
battery leads can be attached to the battery.
