Safety instructions

Correct use/declaration of conformity

The Aastra Phone 312 is a handset for calling via SIP in a WLAN. 
The CE mark on the product confirms its conformity to the technical guidelines for user safety and
electromagnetic compatibility, valid at the time of issuing the corresponding declaration of confor-
mity according to European directive 99/5/EC.

Like every cordless phone, this handset uses radio signals which do not always guarantee a connec-
tion establishment in all circumstances. Therefore as a rule you should never rely solely on cordless
phones for essential communication (e.g. medical emergencies).

Electricity supply/power failure/battery

This product requires an AC supply for the use of the charging point. The electricity can only be dis-
connected from the charging point when the mains adapter is taken out of the socket.

If there is a power failure, all saved information (program and user data) is retained without
changes. 

Important advice on the battery can be found in the section “Precautions when handling the bat-
tery”.

Safety 

The charging point can only be installed and used in a closed building. 
Place the charging point on a non-slip mat.

Do not install the charging point and the handset near:
• Water, moisture or damp areas (e.g. bathroom)
• Sources of heat, direct sunlight or unventilated areas
• Devices, which produce strong magnetic fields, electronic devices, fluorescent lamps, computers,

radio devices, televisions or fax/phone devices

• Areas where the device could be covered, or where its ventilation could be obstructed, or where

water could run into it

• Dusty areas, and areas which are subject to vibrations, jolting or extreme temperature fluctua-

tions.
