Location

The locations determined for the handsets, charging bays and radio units during
the planning phase need to be checked against the following criteria:
• Influence on radio operation
• Ambient conditions
Influences on Radio Operation
Radio operation is affected by the following influences:
• Outside interference (EMC)
• Obstacles in the surrounding area affect the radio characteristic
To achieve optimum conditions for radio operation, observe the following points:
• Optimum radio operation depends on the radio unit ® handset line of sight.
• Walls act as an obstacle to the propagation of radio waves. Losses depend on
the wall thickness, construction material and reinforcement used.
• Do not place radio units and handsets in the immediate vicinity of TV sets,
radios, CD players or power installations (for reasons of EMC, e.g. distribution
boxes, rising power lines).
• Do not place radio units and handsets near X-ray installations (EMC).
• Do not place radio units and handsets near metal partitions.
• Observe the minimum distance requirements between adjacent radio units (see
Fig. 4.83).
• Minimum distance between handsets for fault-free operation: 0.2 m. (The
charging bays of the Office 130 can be linked using connecting strips. How-
ever, operating several phones on interconnected charging bays can lead to
malfunctions.)
• Minimum distance between charging bays with handset on-hook for fault-free
operation: 0.2 m.
