NEC UNIVERGE SV8500 Setup Manual page 7

Observe the following precautions when using any optional batteries:
• The PBX's emergency back-up battery may be a rechargeable lead battery. Check the
emergency battery for an electrical failure.
• Battery acid (electrolyte) is extremely harmful to human skin and eyes. If battery acid
contacts skin, wash the affected area with soap and water. If battery acid contacts the eyes,
flush the eyes with water. In either event, seek medical attention. If there is battery acid on a
cloth, use water to wash the battery acid from the cloth.
• Do not intentionally short batteries. Do not put the battery near a fire or in a fire. Do not
disassemble the battery, drop it or knock it against another object.
• The battery's life expectancy is affected by its environment. The normal battery life is
approximately three years. If the battery is used in an outdoor setting and is exposed to high
temperatures, its life expectancy drops to approximately one year.
• Perform periodic diagnostic tests and maintenance procedures on the emergency battery and
its terminals to ensure their readiness. If there is a power failure and the emergency battery is
not ready, then the PBX will not work. Additionally, a damaged or dead battery, or terminals
that need replacement might cause battery acid to leak, which might cause smoke or a fire.
The battery and terminals are periodic replacement parts (the cost is chargeable to the
customer). A service contract, with the supplier or service technician, to perform routine
maintenance for the battery is recommended.
Do not touch peripheral equipment with wet hands. Do not allow any liquid to touch any of the
peripheral equipment.
Do not touch the printer's internal components when replacing disposables such as a cartridge or a
ribbon. Ensure that the printer is turned off and that it is not hot in order to prevent burns from any
accidental contact with the internal components.
Do not drop the peripheral equipment or knock it against another object. These actions might cause
an equipment failure.
