Installation

Charging procedure before use

At installation or if the telephone has been disconnected, it requires a charging time of approx. 30 seconds before fully operational. During charging the display is empty. When the telephone is ready to use, the display is turned on.

Note: Charging should take place with the handset on hook.

CallerId Detection

During installation of the telephone, the CallerID detectors for both DTMF (Dual-tone multifrequency) and FSK (Frequency-shift keying) are activated until the first CallerID is received. If Message Waiting signals are received by the telephone during this time, this will cause the display to dim. This effect will stop after the first call has been received.

Placing the telephone

•Do not place your telephone on sensitive surfaces. Use a non-slippery pad to protect your furniture from possible damage.

•Do not place your telephone near sources of extreme heat, e.g. near the radiator.

•Make sure that the line cable isn´t creased.

Cleaning the telephone

Use a slightly moistened (not wet) soft cloth or an anti-static cloth and wipe off the telephone carefully. Do not use rough cloth, solvents or aggressive cleaning fluids. Any damages of the telephone, that are caused by non-observance of these instructions, are not part of the liability given by the manufacturer.
