Nortel Networks 4075 User Manual

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 

switches off after approximately 3 to 5 minutes. 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.

CAUTION
Do not install the charger, handset, and accessories in 
the following locations:

•

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

•

near devices that generate strong magnetic fields, 
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.

The handset, if switched off, automatically switches on 
when placed in the charger.
