Recommended separation distances between portable and mobile RF communications equip-
ment and the IH25/1
The IH25/1 is intended for use in an electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or the user of the IH25/1 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the IH25/1 as recommended below, according to the maximum output
power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer.
Notes:
1. At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
2. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorp-
tion and reflection from structures, objects and people.
Electromagnetic environment—guidance
The device uses RF energy only for its
internal function. Therefore, its RF emis-
sions are very low and not likely to cause
any interference in nearby electronic
equipment.
The device is suitable for use in all estab-
lishments, including domestic establish-
ments and those directly connected to the
public low-voltage power supply network
that supplies buildings used for domestic
purposes.
