Care
¤
Wipe down the base station and handset with a damp cloth (no solvents) or an anti-
static cloth.
Never use a dry cloth. This can cause a build up of static.

If the handset should come into contact with liquid:
¤
Switch the handset off and remove the batteries immediately.
¤
Allow the liquid to drain from the handset.
¤
Pat all parts dry, then with the battery compartment open and the keypad facing down
place the handset in a dry, warm place for at least 72 hours (not in a microwave, oven
etc.).

Do not switch on the handset again until it is completely dry.
When it has fully dried out, you will normally be able to use it again.
