Installation

Cautions
l
Avoid installing 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)
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 equipment, 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 from televisions. (both the electronic modular switching system and EMSS proprietary
telephones)
8. Do not obstruct area around the electronic modular switching system. (for reasons of maintenance and
nspection-be especially careful to allow space for cooling above and at the sides of the electronic modular
switching system)

Wiring

Cautions
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 using the same 120 VAC power supply outlet for computers, telexes, and other office equipment.
Otherwise, the KX-T123211’s system operation 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 standard telephone,
data terminal, answering machine,
COmpUter
etc., except proprietary telephone (KX-Tl23230, KX-T123220,
KX-T123250 etc.,).
