The EHE010 is intended for use in the electromagnetic environment specified below.
The customer or the user of the EHE010 should assure that it is used in such an environment.

NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, 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 EHE010 is used exceeds the applicable RF compliance level above, the EHE010
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the EHE010.
b: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
The subject device has been tested and found to comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation.
The product generates, uses, and can radiate radio frequency energy and, if not installed and used
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation. If the product
does cause harmful interference to radio or television reception, which can be determined by turning the
product on or off, the user is encouraged to try to correct the interference by one or more of the following
measures:
a) Reorient or relocate the receiving antenna;
b) Increase the separation between the product and the receiver;
c) Consult the dealer or an experienced radio / TV technician for help.
d) Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Changes or modifications to this product not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
The EHE010 is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the EHE010 can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the EHE010 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 dinmetres (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 structures, objects and people.
