Installation Precautions

This set is exclusively made for wall mounting only. Avoid installing in the following places.
(Doing so may result malfunction, noise or discoloration.)
1. In direct sunlight and hot, cold, or humid places. (Temperature range: 0°C-45°C/32°F- 113°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 install in the same room with the above equipment.)
7. Install at least 1.8 m (6 feet) from radios and televisions. (both the main unit and a key telephone)
8. Do not obstruct area around the main unit (for reasons of maintenance and inspection - be
especially careful to allow space for cooling above and at the sides of the main unit).

Wiring Precautions

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 using the same power supply outlet for computers, telexes, and other office equipment.
Otherwise, the TX-Z 308's system operation may be interrupted by the induction noise from such
equipment.
4. Please use one pair telephone wire for extension connection of (telephone) equipment such as
standard telephones, answering machines, etc., except key telephones.
5. The AC cord must be plugged off during wiring. After all the wiring are completed, plug the AC
cord into an AC outlet.
6. Mis-wiring may cause the system to operate improperly.
7. If an extension does not operate properly, disconnect the telephone from the extension line and
then connect again, or plug off the AC cord of the system and then on again.
8. The TX-Z 308 is equipped with a 3-wire grounding type plug. This is for safety. If you are unable to
insert the plug into the outlet, contact your electrician to replace your obsolete outlet.
9. Use twisted pair cable for Trunk line connection.
10. Trunk Lines should be installed with lighting protectors. (Ask your dealer)
11. The aerial distribution wiring is not allowed.
