special connection to serve as a power-fail telephone. If an AC power failure occurs, the
system automatically connects the power-fail telephone directly to an outside line. Users
can make normal origination and reception of calls on a power-fail telephone during an
AC power failure. The system will automatically disconnect the power-fail telephone
from the outside line as soon as AC power returns....

arrangement, it is possible for a user to determine that certain lines are ringing, such as in
a night transfer (of ringing) mode, and go to the nearest telephone and answer the call.
The most common use for this arrangement is as a night bell eliminating the need for
external equipment as required with the common ringer and auxiliary ringer interface.
The speaker cannot be used for voice response as the path is one-way...

Ringing Line Preference
The system can be programmed on a per station basis to provide ringing line preference
on all lines programmed for ringing at the station. When ringing line preference is
enabled at a station, taking the handset off-hook automatically connects the station to any
outside line that is ringing at it. A line button will not have to be pressed. With ringing
line preference enabled, the telephones denote a ringing line with an orange colored
status light. If a station also has prime...

tries to place a call, the LCD will indicate “System Busy” and deny the call. If you do
install more than one  Scout wireless telephone, Comdial recommends that you leave at
least 10 feet between adjacent base units. The range of each Scout telephone is affected
by the layout and location of the base unit, so it is a good idea to install the base unit in
an unimpeded area and at desk-level or higher.
The Scout...

INTERCOM and dials 9 or presses a preprogrammed button, the system returns a special
dial tone. The caller then has 10 seconds in which to dial some digits; otherwise, the
telephone will return to its idle state. Once a caller begins to dial digits, he or...
