There is no modem board in the machine. The cpu pe rforms the digital func­tions of a modem and carries out digital to analog conversion of facsimile

The battery [A] on the MBU backs up the RAM on the MBU, which contains
system parameters. It also backs up the real time clock in the cpu. This bat­tery is not rechargeable. CN1-9 tells the cpu whether back-up power (CN1-

11) comes from the battery or the + 5V power supply.
A rechargeable battery [B] on the FCU board backs up the SAF memory and

the real time clock for 1 hour. While the main power is on, the + 24V supply
recharges the battery.

If there is data in the SAF memory, the rechargeable battery [B] also backs
up the real time clock, to preserve the MBU battery.
