Place the handset in the charger as shown in the following figure.
Figure 4: Handset installed on charger
CAUTION
The batteries become hot during the charge cycle.
Attention: The handset, if switched off, automatically switches on
when placed in the charger.
Important battery information
Battery pack life varies, depending on handset model and features and
system infrastructure.
Maximum battery pack performance is achieved after a few charge/
discharge cycles.
If multiple battery packs are supplied with your handset, Avaya
recommends that each be fully charged upon receipt to prolong battery
life. Battery packs slowly lose their charge if they are unused. To maintain
After a length of time, battery packs lose the ability to maintain a charge
and perform at maximum capacity, and need to be replaced. This is
normal for all batteries. The recommended battery replacement interval is
every 12-13 months with normal usage.
Any battery which exhibits swelling, cracking, or other abnormality should
be disposed of promptly and properly.
If your battery pack requires replacement, contact your system
administrator.
Use the battery pack only as directed. Heat or cold reduces the
performance and service life of the batteries. Handsets with hot or cold
batteries can become temporarily out-of-service, even if the batteries are
fully charged. Charge the batteries only using the DECT Handset charger
supplied with the handset.
Attention: Use a CPC N0162957 charger if you have an Avaya 4027
or 4070 DECT Handset, and a CPC N0206072 charger if
you have an Avaya 4075 DECT Handset.
Charging guidelines
Observe the following when you charge your handset:
•Overnight charging is best done while the handset is turned off.
•If the handset does not charge, clean battery pa ck , cha rg er , an d
handset contacts with an alcohol swab.
•When the handset is properly seated, the backlight comes on briefly
and the handset beeps to indicate that charging has begun.
•Charge the battery for at least 6 hours before you use the handset for
the first time. This protective measure extends the service life of the
batteries.
Note: The batteries attain maximum power output only after several
charging and discharging cycles.
24
Getting started
•Do not leave the handset inserted into the charger for more than 30
days without using it.
•You can charge and discharge the batteries hundreds of times, but
eventually they wear out. If the operating time (talk and standby time)
becomes significantly shorter than usual, replace the batteries.
•To maintain optimum operating time, periodically discharge th e
batteries by leaving the handset off the charg er and switched on, until
the handset switches itself off. Use only this method to discharge the
batteries. If you want to accelerate the discharge of the battery, you
can enable the display. For more information about configuring power
save, see “Configuring Power save” (page 198).
Note: Extreme temperatures influence the charging capability of the
batteries.
Charging and operating times
Discharged batteries require 6 hours to completely recharge. Completely
charged batteries provide the handset with approximately 8 hours of talk
time and 100 hours of standby time.
WARNING
Use only the batteries that Avaya provides or
authorises.
25
Charge the batteries only using the supplied charger.
Do not replace the batteries in potentially explosive
environments, such as rooms where flammable liquids
or gasses are present.
Do not dispose of batteries in a fire. Recycle or dispose
of batteries in accordance with local regulat ion s.
Getting started
WARNING
You must charge your handset before you reset the
handset time and date. Every time you remove the
battery pack or switch the handset off it loses the time
and date information; you must manually reset it after
you reinstall the battery pack or switch the handset off
and on.
If your system provides the date and time information to
DECT Handsets, the date and time settings update
automatically when you switch on the handset. Contact
your system administrator to determine if you can use
this feature.
Attention: Your handset displays the battery status accurately after
charging for at least 6 hours.
Attention: You must have a mains connection to operate the charger.

including electrical appliances, fluorescent lamps,
computers, radios, televisions, and fax or telephone
terminals
•in locations where the handset can be covered or
where excessive dust is present, or in areas subje ct
to vibration, shock, or extreme temperature
fluctuations
•in locations with poor ventilation
26
Getting started
CAUTION
