device marked with the following
symbol:
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 strength 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 DB686 Honor is used
exceeds the applicable RF compliance level above, the DB686 Honor should be observed to
verify normal operation If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the D8686 Honor.
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
device and the DB686 Honor.
The DB686 Honor is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the u ser of the DB686 Honor can help
prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications device(transmitters) and the DB686 Honor as
recommended below, according to the maximum output power of the communications
device.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance 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.
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
