Please read the following notes concerning installations and connections before installing the
KX-TD500 system.
1) Installation Cautions
• Avoid installing the KX-TD500 system in
the following places. (Doing so may result
in malfunction, noise, or discoloration.)
1. In direct sunlight and hot, cold, or humid
places. [Temperature range: 32°F-104°F
(0°C-40°C)]
2. Sulfuric gases produced in areas where
there are thermal springs, etc. may
damage the equipment or contacts.
3. Places in which shocks or vibrations are
frequent or strong.
4. Dusty places, or places where water or oil
may come into contact with the unit.
5. Near high-frequency generating devices
such as sewing machines or electric
welders.
6. On or near computers, telexes, or other
office equipments, as well as microwave
ovens or air conditioners.
(It is preferable not to be installed in the
same room with the above equipment.)
7. Install at least 6 feet (1.8 m) away from
televisions. (both the KX-TD500 system
and proprietary telephones)
8. Do not obstruct area around the KX-TD500
system. (for reasons of maintenance and
inspection—be especially careful to allow
space for cooling above and at the sides of
the KX-TD500 system)
2) Wiring Cautions
• Make sure to keep the following
instructions when wiring.
1. Do not wire the telephone cable in parallel
with an AC power source, computer, telex,
etc. If the cables are run near those wires,
shield the cables with metal tubing or use
shielded cables and ground the shields.
2. If cables are run on the floor, use
protectors or the like to protect the wires
where they may be stepped on. Avoid
wiring under carpets.
3. Avoid sharing the same power supply
outlet for computers, telexes, and other
office equipments. Otherwise, the
operation of KX-TD500 system may be
interrupted by the induction noise from
such equipments.
4. Please use one pair telephone wire for
extension connection of (telephone)
equipments such as single line telephone,
data terminal, answering machine,
computer etc., except proprietary
