During a power failure, the user presses the battery key to activate the terminal. Data can then be entered and
stored in the SY-765 memory. The time-out will cause the terminal to shut down automatically after the last
use of the terminal, until the battery key is pressed again.
1.4.1 Memory
As a standard feature, the SY-765 Terminal contains a 256 Kbyte user memory, providing storage for data from
more than 10,000 simple operations. This number depends on the length of the programming tables contained
in the memory, and the complexity of the collected data.
The Alarm light “!”, is located to the left of the display. The alarm light is an
LED that lights when at least half of the memory is used; its blinks when the
memory is almost full.
1.2 Internal Components
The SY-765 has two back-up battery modules, one for the real time clock memory and the other for operation
during a power failure.
The standard memory back-up module is a lithium battery, which will keep the internal clock running and the memory
intact, for 30 days during 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.
During a power failure, the user presses the battery key to activate the terminal. Data can then be entered and
stored in the SY-765 memory. The time-out will cause the terminal to shut down automatically after the last
use of the terminal, until the battery key is pressed again.
1.2.1 Memory
As a standard feature, the SY-765 Terminal contains a 512 Kbyte user memory, providing storage for data from
more than 10,000 simple operations. This number depends on the length of the programming tables contained
in the memory, and the complexity of the collected data.
The Alarm light “!”, is located to the left of the display. The alarm light is an
LED that lights when at least half of the memory is used; its blinks when the
memory is almost full.
