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 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. 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.
