1.4 Internal Components
The SY-765 has two back-up battery modules, one for the real time clock memory and the other for operation

intact, for 30daysduring a power failure.
The back-up battery provided (in addition to the standard memory back-up) is a self-recharging system which allows
the terminal to operate during a power failure. The battery provides power for one and a half net hours of use. A shut
down timeout feature enables the terminal to operate for more extended periods of time.
