5.5 Cleaning your telephone
Your telephone does not require any particular servicing. However, it may be cleaned using a soft, damp
cloth.
Use appropriate soap or detergent to clean the surface of the telephone.
5.6 Transporting and protecting your telephone
Your telephone can also be carried in a protective case with swivel clip
(not supplied with the phone, please contact your installation
technician). It is recommended to use the protective case if your
telephone is to be used in an industrial environment (presence of dust,
filings, vapors of diverse origins or its at the risk of being dropped). To
avoid losing your telephone, get into the habit of clipping it onto your
belt.
Insert the phone into the protective case (top end of the phone first).
Make sure that the protective case is correctly closed.
