PRE-INSTALLATION INSTRUCTIONS
'* For details, please refer to the Instructions packed
with each unit.
1. Use twisted pair cable, not straight conductors.
(1) YAZ-90-3 phone employs such components as CPU (microprocessor) and IC chips. Twisted-pair cable must be used to
prevent the unit from being interfered by line inductive noises generated by the surrounding electrical appliances and
from crosstalk and mulfunction caused by cable conductors themselves.
(2) Keep at least 30 cm (!') away from other cable, like AC power lines or paging speaker lines or telephone lines or provide
metal conduit for running cable.
