IVX C-Class with voice mail: Installation Manual
Cautions
Important: This information complies with the requirements of Underwriters' Laboratories (UL) and UL
Standard 60950.
When using this telephone equipment, always exercise basic safety precautions in order to minimize the
risk of fire, electric shock or injury to persons. Before proceeding, please read the following:
• The airflow vents on the IVX case must be free of obstruction for proper cooling. Similarly, do not
install the cabinet in areas of extreme heat or improper ventilation. Never insert objects of any kind
through the ventilation slots on the system cabinet; doing so may result in contact with dangerous
voltages — or cause an electrical short capable of producing fire or shock.
• Do not use liquids or aerosols to clean any IVX equipment; rather, use a cloth that is only
slightly damp.
• The IVX telephone/voice-mail system contains no components that are serviceable by either
non-Resellers or non-manufacturer technicians. All service must be referred to the Reseller for
further handling.
• To reduce the risk of fire, use only 26 AWG or better telecom wire.
Power supply
Always disconnect the power supply and telephone lines from the system cabinet before opening the
case for service or component disassembly or replacement.
Heed all warnings and instructions in documentation or marked on the cabinet or peripheral equipment.
Note: If necessary, review "Wall-mount transformer" (page B.1) for information on the type of power supply for
the IVX C-Class system.
Fuse
Contact the factory before attempting to replace the fuse. The fuse is marked with "F1" and is located at
the top (when the system is installed on the wall) of the motherboard.
Battery
"Caution: There is a danger of explosion if the onboard lithium battery is incorrectly replaced. Replace only
with Ray-O-Vac BR1225 (or equivalent). Dispose of used batteries according to the battery
manufacturer's instructions."
