RE: Equipment ID: BSTGZSRPV1OO
Dear Sir,
it has been brought to our attention that documents Datron provided in support of the
certification process make reference to certain accessory items not certified as part of this
filing.
To correct this oversight, Datron has removed references to these items from the affected
data sheets and will not offer them for sale until such time they are certified. 1 am
attaching me modified pages from the Service Manual to indicate the corrected areas.
Specifically, paragraph 4.1.2.1 concerning antennas and paragraph 4.1.3.1 concerning
batteries have been modified.
With reference to requirements concerning RF Radiation Exposure notices, Datron has
added a label to the exterior of the radio, warning users of the hazard. The engineering
release document showing this label, its text and placement is included with this letter.
Additionally, Datron has added cautionary text to both the user and service manuals
indicating the RF hazard. The sample document showing this text is included with this
letter. It will be incorporated when the manuals are printed for the first time.
Request for additional detail on modulation method and parts listing are also included.
Datron hopes these actions correct the areas of concern noted.
Sincerely,
(lok/

User and Installer RF Exposure Caution
Caution: This radio has been tested and complies with the FCC RF exposure limits
for occupational/controlled exposure environments. This radio is restricted to
occupational use and work—related operations, Where the operator must have
knowledge to control RF exposure conditions. When transmitting, hold the radio in a
vertical position at a distance of 25 cm from mouth, and at least 15 cm from head
and body. Do not transmit for more than 50% of the duty cycle. Transmitting for
more than 50% of the duty cycle can cause the FCC RF exposure compliance limits
to be exceeded. Only use Datron authorized accessories.
