Taking care of the handset
Removing everyday dirt
To clean the handset and the charging shell, simply wipe them with a damp or anti-static cloth.
Never use a dry cloth!
Do not use abrasive cleaning agents.
After contact with liquids
1. Deactivate the handset immediately. Do NOT activate it!
2. Remove the batteries immediately. Leave the battery compartment open.
3. Allow the liquid to drain off:
– Hold the handset in a horizontal position with the open battery compartment facing down.
– Hold the handset in a vertical position with the open battery compartment facing down. Shake
the handset gently, tilting it slightly back and forth.
– Dab all components dry and then leave the handset in a warm spot (not beside a microwave,
oven, etc...) for at least 72 hours with open battery compartment and keypad facing down.
The handset can be put back into operation once it is completely dry.
Storage
To avoid damage, the handset should not be stored with sharp objects, such as, knives or tools,
etc. We recommend using a protective pouch
