Operation during Failure of External Power Supply
During failure of external power supply GB 051 operates, with unchanged output, for
approx. 12 hours from battery. However, it is not able to switch on the cell phone
without external power supply and therefore command RESET is ignored.
Configuration, which you enter in GB 051, will be saved in memory – type EEPROM –
for arbitrarily long time even during disconnection or total discharge of backup battery.
