Safety Guidelines
CAUTION These servicing instructions are for use by qualified personnel only.
To avoid electric shock do not perform any servicing other than that contained in the Operating
Instructions unless you are qualified to do so. Refer to all servicing to qualified service personnel.
When installing any GAI-Tronics telephone equipment, please adhere to the following guidelines to
ensure the safety of all personnel:
• Do not install telephone wiring during a lightning storm.
• All telephone models must be properly connected to earth ground to protect personnel and to
minimize the effects of any electrostatic discharge (e.g. lightning). Please note proper grounding does
not eliminate the need for lightning protection for the telephone or the telephone system.
• Install a UL Listed lightning arrestor on any phone installed where the phone or phone cable is at risk
of being exposed to lightning strikes. The lightning arrestor must be installed as close to the phone as
possible to maximize the protection. It must not be installed within the enclosure supplied with the
phone. Please consult our Service Center at 800-492-1212 for further information.
• Do not install telephone jacks in wet locations unless the jack is specifically designed for wet
locations. Do not touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
CAUTION
• This kit is intended for additional telephone protection only!
• This kit is not intended to substitute for primary or secondary protectors.
• This kit is not intended to replace the UL Listed lightning arrestor that your system should have
installed directly outside the telephone enclosure.
