Replacing battery
WARNING!
Only qualified service personnel may install this equipment. The instructions in this manual
are intended for use by qualified service personnel only.
Only qualified persons should service the system.
The installation and service of this hardware is to be performed only by service personnel
having appropriate training and experience necessary to be aware of hazards to which they
are exposed in performing a task and of measures to minimize the danger to themselves or
other persons. Electrical shock hazards from the telecommunication network and AC mains
are possible with this equipment. To minimize risk to service personnel and users, the system
must be connected to an outlet with a third-wire Earth.
Service personnel must be alert to the possibility of high leakage currents becoming available
on metal system surfaces during power line fault events near network lines.
These leakage currents normally safely flow to Protective Earth via the power cord.
Therefore, it is mandatory that connection to an earthed outlet is performed first and removed
last when cabling to the unit. Specifically, operations requiring the unit to be powered down
must have the network connections (exchange lines) removed first.
Intrinsic safety
Do not install the unit in conditions where there is a danger of electrically ignited explosions.
Exposure to sunlight, heat and moisture
CAUTION
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS
