Introduction
Follow these instructions if your AirCell telephone is equipped
with one or more Cordless Handsets. A Cordless Handset system
consists of a portable handset plus a base station cradle.
Refer to your Users Manual for basic handset features, which
also work with a Cordless Handset. Review this document for the
additional features unique to a Cordless Handset.
Viewing the Display
A Cordless Handset provides a specialized display, shown below,
which is slightly different from corded handsets. For instance,
there is no dot in the bottom left indicating the phone has power.
01 – Battery charge status indicator. Each additional dark sector
indicates a greater remaining charge.
02 – In Use displays when the phone is in use. Mute displays
when the handset microphone is off. ICom displays when the
handset microphone is on.
03 – Signal strength indicator. Shows the strength of signal to
the handset from the base station. Each additional bar indicates a
stronger signal.
04 – Iridium displays when using the Iridium satellite network.
No-Line displays if a data call is in process.
05 – No Svc displays when the phone is not registered or when
service is unavailable.

Charging the Battery
To fully charge the handset battery, place the handset in the base
station cradle for three hours. The handset charges when it is in the
cradle and the avionics power is on. For this reason, you should
always return the handset to the cradle when not making calls.
When fully charged, the Cordless Handset provides up to four
hours of continuous use. Note that dialing uses more battery
power than talking. If the battery voltage gets too low for normal
operation, the handset will stop working until charged.
Staying in Range
The Cordless Handset system is designed to provide a good signal
between the handset and base station in any size business aircraft.
In some cases, it may also work outside when close to the aircraft.
To prevent interference with cordless phones on the ground, or in
nearby buildings, you should limit use to within the aircraft.
Activating Alarms
Two alarms are built into the Cordless Handset system. Both will
sound a tone and show Return Phone on the handset display.
• Inactivity alarm. This alarm reminds you if the handset is out
of the base station and unused for a preset period of time. To
maintain the battery charge, return the phone to its cradle.
• Walk-off alarm. This alarm alerts you if the handset strays
too far from the base station. It helps keep the handset within
optimum operating range, and prevent the handset from being
accidently removed from the aircraft.
The time period for the inactivity alarm, and the distance for the
walk-off alarm, can be adjusted during the equipment installation.
Using Multiple Cordless Handsets
You can simultaneously use multiple cordless handsets in the
aircraft. To prevent problems with the system, be sure that you
return each handset only to its own matching base station cradle.
(Label matching handsets and cradles for easy identication.)
