Guidance and manufacturer's declaration – electromagnetic immunity
The IH 60 is intended for use in the electromagnetic environment specified below.
The customer or the user of the IH 60 should assure that it is used in such an environment.

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from struc-
tures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment
due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the
IH 60 is used exceeds the applicable RF compliance level above, the IH 60 should be observed to verify normal operation. If abnormal per-
formance is observed, additional measures may be necessary, such as re-orienting or relocating the IH 60.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the IH 60
The IH 60 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the IH 60 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the IH 60 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 metres (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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from struc-
tures, objects and people.
