10. GENERAL CARE AND MAINTENANCE

This telephone is a precision electronic instrument. While in use and storage, care should

be taken to avoid rough handling, extreme temperature, and damp or dirty environments.

CLEANING

NEVER use aerosol sprays or other chemical agents or substances that leave a residue

(furniture polish for example).

Use a mild detergent and a damp, clean cloth when cleaning. Do not allow moisture to

enter the telephone interior - damage may result!

FAILURE TO OPERATE AND SERVICE DIFFICULTIES

If telephone service problems occur at any time, it is recommended that the installation

procedure described in this manual be re-checked.

If a fault occurs, try to determine if the fault is with the telephone, or with the network or

system to which the telephone is connected:

Disconnect the “suspect” telephone, and test the line with a substitute telephone. If the

telephone service then operates satisfactorily, the fault is in the “suspect” telephone.

Test the “suspect” telephone on a known good line. If the fault still occurs, the fault is in

the “suspect” telephone.

Consult your Interquartz dealer for further advice if necessary.
