WARNING

Do not open the handset when it is switched on or connected to the charger; doing so can expose you to high voltage. Only authorised service personnel must perform repairs.

Do not dispose of defective or used batteries in municipal waste. Return old batteries to the battery supplier, a licensed dealer, or a designated collection facility. Do not destroy batteries.

Do not use the handset, remove, install, or charge batteries in hazardous environments (such as explosive environments), hospitals or vehicles.

If your interior handset becomes wet, do not use a blow dryer or oven to dry it. Switch off the handset, remove the battery, shake out excess liquid from the handset, and let it dry for 72 hours at room temperature.

CAUTION

The handset product contains a magnet. Do not allow metallic objects to come in contact with the magnet, because that can deteriorate audio quality and damage the handset. Do not allow the charger and the b attery to come into contact with conductive objects, such as keys, paper clips, rings, or bracelets.

Keep the handset at least 10 centimetres away from other electronic equipment.

WARNING

Keep the charger, handset, and accessories out of reach of small children.

Charger

CAUTION

The batteries become hot during the first charge cycle.

Attention: The handset, if switched off, automatically switches on

when placed in the charger. The DECT 4027 and 4070 Handsets use the CPC

N0162957 charger.

Getting started

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 fully charged. Charge the batteries only with the DECT 4027 and 4070 Handset charger supplied with the handset.

Charging guidelines

Observe the following guidelines 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.

• The batteries attain maximum power output only after several charging and discharging cycles.

• Do not leave the handset connected to the charger for more than a month 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 charg er and switched on, until the handset switches itself off. Use only this method to discharge the batteries. You can disable the display to accelerate battery discharge. For more information about configuring power save, see “Configuring

power save” (page 167).

• Extreme temperatures influence the charging capability of the batteries.

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 with 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.

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. Your handset displays the battery status accurately after charging for at least 6 hours.

If your system can provide 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: You require a mains connection to operate the charger.

Getting started

CAUTION

Do not install the charger, handset, and accessories near the following:

• water, moisture, sources of heat, or direct sunlight

• devices that generate strong magnetic fields, electrical appliances, fluorescent lamps, computers, radios, televisions, and fax or telephone terminals

• areas where the handset can be covered or in excessive dust, and areas subject to vibration, shock, or extreme temperature fluctuations

• 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.

Charge display

The battery charge status appears on the display screen. When the battery is nearly discharged, the battery symbol flashes and a warning tone sounds. If you are on a call, approximately 3 to 5 minutes of talk time exists before the handset switches off. If you are not on a call and the handset is not in the charging station, the message “Battery empty” appears on the display. You cannot make calls while this message appears.
