Charging the batteries
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
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
22
Getting started
fully charged. Charge the batteries only using the DECT Handset charger
supplied with the handset.
Attention: Use a CPC N0162957 charger if you have a DECT 4027 or
4070 Handset, and a CPC N0206072 charger if you have a
DECT 4075 Handset.
Charging guidelines
Observe the following when you charge your handset:
• 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.
• 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 the
batteries by leaving the handset off the charger 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 186).
Note: Extreme temperatures influence the charging capability of the
batteries.
23
Getting started
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 Nortel provides or
authorises.
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 regulations.
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.
24
Getting started
CAUTION
Do not install the charger, handset, and accessories in
the following locations:
• near water, moisture, sources of heat, or direct
sunlight

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 subject
to vibration, shock, or extreme temperature
fluctuations
• in locations with poor ventilation
CAUTION
Use only the plug-in AC adapter and battery type
supplied, and use only approved accessories.
Ensure the mains voltage of the adapter matches the
local mains voltage.
Do not use AC adapters that are visibly damaged
(cracked or broken) and keep the ventilation slits on the
AC adapters free from obstruction.
Attention: The handset, if switched off, automatically switches on
when placed in the charger.

A battery charge status symbol appears on the display. When the battery
is nearly discharged, the battery charge status symbol flashes and a
warning tone sounds. If you are on a call when this happens, the handset
