8. 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 leaves a residue (never use furniture polish for example).
Use a mild detergent and a damp clean cloth when cleaning. Do not allow moisture to enter the telephone's interior - damage may
result!
FAILURE TO OPERATE AND SERVICE DIFFICULTIES
If telephone service problems occur at any time, it is recommended that you first re-check the installation procedure described in this
user guide.
If the telephone still fails to operate correctly, 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 (known to be good) telephone. If the telephone service then
operates satisfactorily, the fault is most likely 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.
