2.10.1 Overview

Required Distances between Equipment

Maintain the distances listed below between equipment in order to prevent noise, interference or the disconnection of a conversation. (The distance may vary depending on the environment.)

Equipment

CS and office equipment such as a computer, telex, fax machine, etc.

CS and PS

Each CS

Each PS

PBX and CS

Distance

More than 2 m

More than 1 m

More than 3 m

More than 0.5 m

More than 2 m

If multiple CSs cover the same area, the phone connection may become noisy or the number of possible simultaneous calls with PSs may decrease due to interference between the CSs. For details, refer

to "2.10.5 Site Survey—Testing the Radio Signal Strength".

The required distance between CSs may vary depending on the environment of the installation site and conditions in which the wireless system is used. Conduct a site survey to determine the appropriate distance.
