1.6.2. Memory Back-up 

The +5VBAT supply from the lithium battery [A] backs up the system RAM
which contains system parameters and programmed telephone numbers,
and the real time clock in the main CPU. 

BRO China model:
Two dry cells [B] and the dc/dc converter on the FCU back up the DRAM, if
there is data in the SAF memory and the power is switched off.
The dry cells generate about 3 volts (max. 3.2 volts). The dc/dc converter
(IC30) lifts this voltage to 5 volts so it can be used as the +5VD supply for
SAF backup. The CPU monitors the voltage of the +5VD supply with the
VDVDET signal. When the dry cells have run down, and the voltage is lower
than 4.4 volts, the CPU stops the dc/dc converter by dropping 1SAFFG to low
and the machine stops backing up the memory.

There is no battery switch for the battery [B].
