GUIDANCE AND MANUFACTURER'S DECLARATION
The Multisport Pro Precision is intended for use in the electromagnetic environment specified below. The customer or
the user of the Multisport Pro Precision 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 Multisport
Pro Precision is used exceeds the applicable RF compliance level above, the Multisport Pro Precision should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Multisport Pro Precision.
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 FREE ACTION
The Multisport Pro Precision is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of Multisport Pro Precision can help prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the Multisport Pro Precision as recommended below, according to the maximum

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.
