Caring for your telephone
Wipe the unit with a
damp cloth
or an
antistatic cloth
. Do not use solvents or microfibre cloths.
Never
use a dry cloth; this can cause static.
Contact with liquid
If the device comes into contact with liquid:
§§1§§
Unplug the power supply
.
§§2§§
Allow the liquid to drain from the device.
§§3§§
Pat all parts dry. Place the device (the keypad facing down) in a dry, warm place
for at least
72 hours
(
not
in a microwave, oven etc.).
§§4§§
Do not switch on the device again until it is completely dry.
When it has fully dried out, you will normally be able to use it again.
In rare cases, contact with chemical substances can cause changes to the telephone's exterior.
Due to the wide variety of chemical products available on the market, it was not possible to test
all substances.
Using insert strips
The phone is supplied with insert strips for the function keys. If you require more blank insert
strips for the function keys, they are available as a PDF file at www.teldat.de.
