NSQ412 Four-Line Caller ID Telephone Owner’s Manual 25
POWER FAILURE OPERATION
The NSQ412 will operate during a power
failure as long as the 9V battery is
installed and in good condition. Many of
the station’s advanced features are
turned off when operating only on the
battery. This is to prolong use. The fol-
lowing features will operate from only
battery power:
a. the clock
b. basic telephone operation (incom-
ing and outgoing calls) on all 4
CO Lines in handset and headset
mode (no speakerphone)
c. the LCD display and Line LEDs
If talking on the speakerphone and a
power failure occurs, the call will remain
connected. Pick up the handset to con-
tinue the conversation. A call that is on
hold will be dropped.
The phone will reinitialize when the a. c.
power is restored. This is normal. The
station will wait until it is idle before the
initialization will occur.
All other features will not operate.
NOTE: The telephone will not operate
during an electric power failure if the
battery is dead or missing.
Line Status Indication
The telephone will detect the status for
non-system devices that may be con-
nected to the CO Lines (single line
phone, fax, modem, etc.). When a non-
system device goes off-hook, the station
CO Line LED will illuminate. After the
non-system device goes on-hook, the
station CO Line LED will turn off. NOTE
:
When a non-system device goes off-
hook, any one of the system telephones
can pick up the call by pressing the [CO
Line] key. Once a system phone picks up
the call, the privacy feature is activated
and no other system telephone can listen
to the call.
Disabling Unused Lines
The station can disable access to CO
Line functions that are not being used at
it. This is done in programming mode.
The [CO Line] key and CO Line LED are
disabled for any line that is programmed
to Off.
Non-Square Operation
The telephone’s wiring configuration is
non-square for CO Lines 2, 3 and 4. This
means that Lines 2, 3 and 4 do not have
to share the same telephone numbers for
every station. Any station can have its
own private line(s) or, the line(s) can be
shared between some of the phones.
Groups can be set up in programming to
allow transferring, conferencing and Line
Status indications to work on shared
lines. By default, Line 2 belongs to Group
2, Line 3 to Group 3 and Line 4 to Group
4.
For example, if telephone number 555-
3333 is used on Line 3 on stations 11
and 12 and 555-4444 is used on Line 3
on stations 13 and 14, the Line Group
should be changed from 2 to 5 on sta-
tions 13 and 14. When this is done and
station 11 is off-hook on Line 3, station
12 will show Line 3 is in use, but stations
13 and 14 will not. Station 11 can trans-
fer the Line 3 call to station 12 (which is
in the same group), but cannot to sta-
tions 13 and 14 (because they are in a
different group).
