This frequency band is reserved for distress beacons.
RF EXPOSURE
ATTENTION!
This radio is intended for use in occupational / controlled conditions, where users
have full knowledge of their exposure and can exercise control over their exposure
to meet FCC /ISED limits. This radio device is NOT authorized for general
population,
consumer, or any other use.
RADIO OPERATOR
It is the responsibility of the Repeater Operator to ensure that Maximum
Permissible Exposure (MPE) limits are observed at all times during repeater
transmissions. If this vehicular repeater is used in combination with a separate
Mobile radio transmitter, the Repeater operator must ensure at all times that no
person comes within the MPE
distance from the vehicle body to ensure compliance with the FCC/ISED RF energy
exposure limits for the general population.
The minimum lateral distance between all possible personnel and the body of the DVRS
equipped vehicle must be as specified in Table 1 (Stand-alone DVR) and Table 2 (DVR
interfaced to a Mobile Radio i.e. DVRS).
Failure to observe the MPE distance exclusion area around the antenna may expose
persons within this area to RF energy above the FCC exposure limit for bystanders
(general population).
