• Do not use the telephone to report a gas leak in the vicinity of the leak.

Lithium batteries

A lithium battery is fitted to the real time clock on the control unit motherboard.

Warning:

The Lithium battery must only be replaced by Avaya personnel or authorized

representatives. There is a danger of explosion if the battery is incorrectly replaced. Replace

only with the same or equivalent type recommended by the manufacturer. Dispose of used

batteries according to the manufacturer's instructions.

Lightening protection/hazard symbols

Lightning protectors — The buildings lightning protectors must be verified as follow:

1. Check the lightning protectors at the trunk cable entry point to the building housing

the B5800 Branch Gateway system , paying special attention to the lightning

protection grounding. Report any problems, in writing, to the telephone company.

2. Equipment that is designed to be connected using internal wiring is typically not

lightning protected. Hence, B5800 Branch Gateway extension cabling must not

leave the building. For installations where telephones and/or other standard (tip/

ring) devices are installed in another building then lightning protection is required,

see

Out of Building Telephone Installations on page 72.

Hazard Symbol — The shock hazard symbol is intended to alert personnel to electrical

hazard or equipment damage. The following precautions must also be observed when

installing telephone equipment:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for

wet locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

• Always use caution when working with telephone lines.
