The side of the telephone features a 3.5 mm jack connector for headphone / external microphone. Contact your retailer
for information on the various headphone models available.
10.6 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.
10.7 Transporting and protecting your telephone
To avoid losing your telephone, get into the habit of clipping it onto your belt. Your telephone can also be carried in a
protective case.
Various models of carrying case are available. Ask your installation technician for information. It is vital to use the
special protective carrying case if your telephone is to be used in an industrial environment (presence of dust, filings,
vapours of diverse origins and risk of being dropped). If the telephone is used with a carrying case, the belt clip must
be removed.
