Keep the unit away from static electricity and electrical noise
If there is a possibility of static electricity or electrical "noise" occurring where the keyphone
system is installed (due to carpets, electrical machinery, etc), measures for preventing this
should be put in place.
Install the unit where it is not exposed to harmful conditions
Be careful not to expose the system to direct sunlight, corrosive vapour, dust, regular vibra-
tion or high levels of magnetic fields generated by motors or copying machines.

Precautions for Installation

Selecting Location
Select a location having sufficient space and levels of brightness to facilitate installation.
Preventing Static Electricity
The unit should not be installed in a room with carpets. To ensure safety, discharge any static
electricity by touching the metal portion of a grounded object or the ground connection on the
system before installing or repairing the system.
In addition, for protection and reliable operation of the system, standard grounding conditions
should be met.
Cable Requirements
Select a location which minimises the length of system cables, and ensure that all cables to
and from the system are not damaged. In addition, take care to protect all cables from elec-
tromagnetic interference; for instance, by keeping them at a safe distance from cables for
other equipment.
