FAILURE TO OPERATE AND SERVICE DIFFICULTIES
If you are satisfied with the operation of your telephone service, your installa- tion is completed. However, if telephone service problems occur at any time, it is recommended that the installation procedure described in this manual be rechecked.
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 tel- ephone. 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 the 'Suspect' telephone.
Consult your Interquartz dealer for further advice if necessary.
11. THUNDERSTORMS
The telephone, in common with household electrical appliances, can be a source of electric and acoustic shock during thunderstorms. The possibility of a telephone user experiencing a shock is minimal. Nevertheless, customers should be aware of some simple precautions to follow during thunderstorms:
*Use your telephone only for calls of the utmost urgency. Keep these calls brief.
*Whilst using your telephone keep clear of electrical appliances and metal fixtures such as: stoves, air conditioners, refrigerators, window frames and sinks.
