4. To test, remove the system mains power plug from the mains socket. The telephone system
should continue to function. Note: it may be necessary to leave the system running for a period
to ensure there is sufficient charge available in the batteries.
The unit will allow the PABX to operate without mains power. The period of operation is dependent
on both the battery capacity, and the level of use of the system. For two fully charged 1.2Ah batteries
the system is guaranteed to operate for up to 1 hour, though the operation period may well extend
further. When the batteries are exhausted the system will revert to power failure mode, where
exchange lines are directly connected to power fail extensions.
The green led on the front case of the telephone system will light to indicate it is receiving power.
After the batteries are charged (approx. 4 to 5 hours) then the system will run without mains power
for between 1 and 3 hours depending on the usage of the system and the number and duration of
extensions ringing.
Firmware upgrade (212 only)
The 212 telephone system uses on-board flash memory for its system software. This may be updated
by users. This procedure requires the V24 option card, the PC programming tool and a new
firmware file for the 212 system.
1. Run the PC software tool for the 212.
2. Go to File Upgrade flash and select the upgrade software file.
3. Power down the 212 system and power-up, the PC will start updating the flash. The procedure
will take out 4 minutes.
4. Once the update is finished, exit the PC program and power down and up the 212 system.
Remote System Maintenance and Configuration
