Recommended separation distance
OMRON M24/7
is intended to be used in electromagnetic environment with controlled RF
disturbances. The purchaser or user of M24/7may help to reduce electromagnetic disturbances
by de ning the separation distance between the transportable or mobile RF telecommunication
equipment (transmitters) and
OMRON M24/7
, depending on the highest output power of the
telecommunication equipment.

If this table does not contain the highest output power of the transmitter, the d separation
distance [m] can be calculated by the formula, depending on the frequency of the transmitter,
where P is the rated highest output power of the transmitter [W].
1. note: in case of frequency 80MHz or 800 MHz, the formula for the higher range is
applicable.
2. note: These are guidelines. Actual conditions may vary.
