A battery is provided on the CPUII( )-U( ) ETU for the Electra Elite IPK II system to
retain System Program Memory when power fails. When fully charged, the battery
maintains backup power for approximately seven years. System Data, Speed Dial
Memories, and Clock/Calendar functions are protected by the backup battery. After
power is restored, the system returns to normal operation.

A built-in battery provides complete system operating power for approximately 30
minutes during commercial power outages. When optional (locally provided) batteries
are connected and fully charged, full system operation can be maintained for an
extended time. Actual time depends on system configuration, traffic conditions, and
the capacity of the batteries.
C a l l A p p e a r a n c e ( C A P ) K e y s
This feature automatically places an outside call on a Call Appearance key when the
system is operated as a hybrid (Multifunction) system. These keys can be assigned
on any Multiline Terminal or the same key can appear on multiple terminals. This
feature allows efficient call handling when numerous CO calls are received and a
limited number of CO line key appearances are available.
Once a Call Appearance (CAP) Key call is set up, the user can handle it like any other
trunk call. For example, the user can place the call on hold, transfer it to a co-worker
or send it to a park orbit. An incoming call will be answered on the first available CAP
key, beginning with the lowest numbered key. If keys 1~3 are Call Appearance (CAP)
Keys, for example, the first incoming call will be answered on key 1. If key 1 is busy,
the next call will be answered on key 2. If keys 1 and 2 are busy, the next call will be
answered on key 3. If all three keys are busy, additional incoming calls queue for the
first available key.

Call Arrival (CAR) Keys are available software extensions available on the Basic and
Expanded Port Packages. A Call Arrival Extension assigned to a line key, can appear
and ring on an individual station or multiple stations. Call Arrival Keys are only busy
when in the ringing state and are not used during the talking state.
Call Arrival Keys are shared with the Virtual Extensions (VE's). In virtual extension
mode, the key acts as a secondary extension. Up to 256 CAR/VE keys are provided.
