							If you place a fully charged battery in the charger, it will detect the
charged condition and cancel rapid charging. The LED changes to
amber, red, and then green.
NOTE: Do not use a battery before it has completed the rapid charge
cycle, even if the handset battery icon reports full strength. The
battery will have a diminished talk/standby time under these
conditions.
If you find that a battery is not lasting as long as it did initially, try to let
the battery run down as much as possible before charging it.
To discharge a battery,
The rear pocket of the charger has a discharge function which is initiated
when the charger detects that discharging is necessary. You should try to
discharge a battery when it shows a significant reduction in talk/standby
time.
1. Insert the battery in the rear pocket of the charger.
2. If the LED alternates between green and amber, leave the battery
in the charger to complete discharging.
After the discharge cycle is complete, the LED changes to red to
indicate rapid charging is in progress.
3. When the LED changes to green, remove the battery.

							Multi-System Use
12.1 Multi-System Use
Your system administrator can program one or more system and handset
IDs into your handset, which lets you use your handset in one or more
Air Impact systems. If you need to use your phone in another Air Impact
system, you can ask your system administrator for assistance in adding
the appropriate IDs to your phone.
12.1.2 Moving Between Systems
If you wish to move from the range of one Air Impact system to another
system without losing your call, there are several steps you must follow.
To transfer a call between Air Impact systems,
1. Before leaving the range of current Air Impact system, press
FLSH, then pressEND(this puts your call on hold).
2. Move so that you are inside the range of the second Air Impact
system.
3. PressCALL, then pressFLSHto retrieve your call.

13.1 Troubleshooting
Symptom Possible Cause
Called party can hear you
but cannot be heard.
Conversation is broken up.
Handoff clicks occur during
conversation.The handset signal strength is
inadequate. Try moving closer to a base
station. For best results the signal
strength indicator should show three to
five bars.
Handoff clicks are normal when
moving between base stations.
Display does not contain
date, time, and signal
strength.The handset is not locked onto a base
station. Try powering off and powering
on the handset or moving to another
location closer to a base station. Note
that sometimes it may take up to a
minute for the full display to appear.
No dial tone.Make sure the handset keypad is not
locked and check the handset volume
level. If the problem remains, the
handset is not locked onto a base
station. Try powering off and powering
on the handset or try moving to another
location closer to a base station.

Weak or delayed
dial toneCheck the handset volume level. Then make
sure to align the handset with your ear rather
than your mouth and don’t watch the display.
Consider using the predial method to make
calls by dialing the number and pressing the
CALLbutton (rather than pressingCALLand
waiting for dial tone).
NO SERVICE!
messageYou pressedCALLon a handset that is not
locked, due to being out or range or all eight
channels of the base station are being used for
other calls.
Try powering off and powering on the handset
or try moving to another location closer to a
system base station. A handset is properly
locked when you see the handset date, time,
and signal strength icons after power up.
SYSTEM BUSY
messageThe handset was locked onto a base station
when theCALLkey was pressed and was able
to request service, but did not get an answer
from the base station. One or more base station
channels may be in a maintenance busy state or
the handset may not be locked well enough to
complete the request for service
Unexpected digits in
displayIt is very easy to inadvertently press keys on
the handset keypad while the handset is not in
use. Consider using the keypad lock feature. To

							Symptom Possible Cause
Battery has
diminished
talk/standby timeTry discharging and recharging the battery.
Another possibility is that a fully charged handset
left unpowered for a long period of time will
slowly drain.
Do not remove a battery from the charger before
the green LED appears, because the handset
battery strength icon shows full power after a
short period of charging. You should let the full
charging cycle complete before using batteries.
You should also use the handset during the day
and recharge it at the end of the day, rather than
performing intermittent charging during the day.
Charger has green
flashing LEDTry recharging the battery. If the problem
continues, the battery may be defective.
