Wiring Precautions
Be sure to follow these precautions when wiring:
• Do not wire the telephone cable in p ar allel with an AC powe r so urce , su ch as a computer,
fax machine, etc. If the cables are run near those wires, shield the cables with metal tubing
or use shielded cables and ground the shields.
• If the cables are run on the floor, use protectors to prevent the wires from being stepped
on. Avoid wiring under carpets.
• Do not use the same power supply outlet for computers, fax machine, and other office
equipment to avoid induction noise interruption when using the MBX IP.
• The power and battery switches must be OFF during wiring. Af ter wiring is completed, the
power switch may be turned ON.
• Incorrect wiring may cause the MBX IP System to operate improperly.
• If an extension does not operate properly, disconnect the telephone from the extension
line and then re-connect, or turn the System power OFF and then ON again.
• Use twisted pair cable for connecting CO lines.
