3. Avoid using the same power supply outlet for computers, telexes, and other office
equipment. Otherwise, Hybrid IP-PBX operation may be interrupted by the induction noise
from such equipment.
4. Please use 1-pair telephone wire for extension connection of (telephone) equipment such
as standard telephones, data terminals, answering machines, computers, Voice
Processing Systems, etc., except PTs (e.g., KX-T7600 series).
5. The power switch of the Hybrid IP-PBX must be off during wiring. After the wiring is
completed, turn the power switch on.
6. Mis-wiring may cause the Hybrid IP-PBX to operate improperly.
7. If an extension does not operate properly, disconnect the telephone from the extension line
and then connect again, or turn the power to the Hybrid IP-PBX off and on again.
8. The Hybrid IP-PBX is equipped with a 3-wire earthing type plug. This is a safety feature.
If you are unable to insert the plug into the outlet, contact your electrician to replace your
obsolete outlet. Do not defeat the purpose of the earthing-type plug.
9. Use twisted pair cable for trunk connection.
