Cautions
Important: This information complies with the requirements of Underwriters’ Laboratories
(UL) and UL Standard 1950.
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 IP PBX must be free of obstruction for proper cooling. Similarly, do not
install the IP PBX in areas of extreme heat or improper ventilation. Never insert objects of any kind
through the ventilation slots on the IP PBX; 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 IP equipment; rather, use a cloth that is only slightly damp.
The IP telephone/voice-mail system contains no components that are serviceable by
either non-dealers or non-manufacturer technicians. All service must be referred to the dealer for
further handling.
To reduce the risk of fire, use only 26 AWG or better telecom wire.
Power supply (24V)
Always disconnect the power supply and telephone lines from the IP PBX before opening the case
for service or component disassembly or replacement.
Heed all warnings and instructions in documentation or marked on the IP PBX or peripheral equipment.
Fuse
Contact the factory before attempting to replace the fuse. The 5.0A fuse is located on the mother-
board directly next to the power jack marked with “F1.”
Battery
Caution: There is a danger of explosion if the onboard lithium battery is incorrectly replaced.
Replace only with Rayovac
®
BR1225 (or equivalent). Dispose of used batteries accord-
ing to the battery manufacturer’s instructions.
