time needed to warm up the paging amplifier, so
the switch can be in either position when the
paging function is not being used.
6. This switch activates "Programming" of the "Secretary
transfer", "master/substation", and/or "executive priority"
functions at station #200. However, since the "PROGRAM
switch", which fulfills the same function, is provided on
the front panel of the CPU model, this switch does not
have to be used, and should be kept in the OFF position.
[B] Connecting
Jack
for
back up battery
This jack serves as the connection to the back up
batteries and therefore prevents cancellation of the
function of functions (one or more of the 3) program-
med at station #200 in the event of a power failure
or the accidental disconnection of the exchange from
its power source. (In the illustration Fig. 23, the
three cylinders lined up next to the connecting jack
are the back up batteries.)
