Back-up battery
This small back-up battery maintains the clock and calendar functions while the
mains power to the RPC-80 is switched off. It has no connection with the batteries in
the monitors.
The battery should last approximately ten years but we recommend that you replace
it every seven years. The date that the battery is fitted is saved in the RPC-80 and a
warning starts to be issued every week after the battery is seven years old.
When it becomes necessary to replace the battery you will need to record the date of
he change so that any present 7 year warning messages are cancelled and future 7-
year warnings can be issued correctly.
After setting the RPC-80 ID as above you will see FINISHED RPC-80 SETUP?
Normally you will press the YES button and return to the main menu. This display is
really a screen to "hide" the battery date setting section from accidental use.
Obviously it is important not to change the battery fitting date unless you have
actually fitted a new battery.
If you answer NO to FINISHED RPC-80 SETUP? the display will change to RPC-80
BATTERY CHANGE with YES and NO buttons. This display alternates with one showing
today's date. Press YES only if you have just fitted a new battery. If the date is
incorrect you will get a chance to change it later.
The display now changes to IS DATE CORRECT? still alternating with the date display.
If you need to change the date press NO. The date in the RPC-80's calendar can
now be changed. After changing the date you will be returned to the IS DATE
CORRECT? display. The CANCEL button allows you to leave this section without
changing any calendar settings and without disturbing the battery fitting date. Press
YES only if you have just fitted a new battery and the date is correct. The battery
fitting date will be recorded.
Do not change the battery fitting date unless you have just fitted a new battery.
