Wipe the base station and handset with a damp cloth (do not use solvent) or an 

antistatic cloth. Never use a dry cloth. This can cause static. 

If the handset should come into contact with liquid, on no account switch the device 

on. Remove all batteries immediately.
Allow the liquid to drain out of the device, and then pat all parts of the device dry.
Keep the handset with the batteries removed in a warm, dry place for at least 72 hours.
