EPM 300(C)
6. Recommendations
EPM 300 and EPM 300C has an internal antenna. The described area should not be covered
by metal or other shielding material. It is recommended to hold EPM 300(C) below this an-
tenna area.
Signal strength of radio signals decreases with increasing distance between transmitter and
receiver. The transmission range also depends on the materials used in the building.
The transmission range is reduced by:
increasing the distance between transmitter and receiver
shielding by metal or massive walls
mounting transmitter or receiver on the floor or close to the floor
high humidity in materials
devices generating RF interferences such as computers, audio & video equipment
or electronic gear controls for lamps. A minimum distance of 0.5 m should be kept.
