1. Be careful about damage by static electricity as the
CPU-56 incorporates CMOS IC's. Do not touch com-
ponents and connectors.
2. Turn off the AC power switch when you take out or
insert the CPU-56 unit, or any other unit.
3. Always insert the CPU-56 unit into the "CPU" slot.
Otherwise, there is a danger that the unit will be
damaged.
4. Make sure mini-jumper for battery back-up is always
placed in the ON position each time it is used.
5. Incorrect setting of function select switches may lead
to incorrect performance.
6. Even if you do not need any programming functions, be
sure to carry out initial programming and registration
at station No. 200 when you install the new unit.
Otherwise, other functions may not work properly.
7. The Ni-Cd battery GB50-3FA1 is capable of saving im-
portant memory registration data even at times of
power failure and we suggest you replace it at least
every 4 or 5 years.
After the change again set up station No.200
programming of the previous functions in the
exchange.
8. When shipping the CPU-56 unit independently, place
the mini-jumper for battery back-up in "OFF" position.
Then cover CPU back with cardboard, wrap connector
section in aluminium foil and put it in a conductive
bag.
