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 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-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
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.
Fuse
Contact the factory
before
attempting to replace the fuse. The fuse is located on the motherboard
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 Ray-O-Vac BR1225 (or equivalent). Dispose of used batter-
ies according to the battery manufacturer’s instructions.”
