Users Manual

• Institute of Electrical and Electronic Engineers (IEEE) C95.3-2003 Edition.

To control exposure to yourself and others and ensure compliance with the general

population/uncontrolled environment exposure limits always adhere to the following procedures:

Guidelines:

• User awareness instructions should accompany device when transferred to other users.

• Do not use this device if the operational requirements described herein are not met.

Instructions:

• Transmit no more than the rated duty factor of 50% of the time. To transmit (talk or send data),

assert the PTT input pin. To receive calls, un-assert the PTT input. Transmitting 50% of the time,

or less, is important because this radio generates measurable RF energy exposure only when

transmitting (in terms of

measuring for standards compliance).

• Transmit only when people are at least the recommended minimum lateral distance away, as

shown in Table 1, from a properly installed according to installation instructions, externally-

mounted antenna.

NOTE - Table 1 lists the recommended minimum lateral distance for bystanders in an

uncontrolled environment from transmitting types of antennas (i.e., monopoles over a ground

plane, or dipoles) at several different ranges of rated radio power for mobile radios installed on a

vehicle.

Table 1. Rated Power and Recommended Lateral Distance for quarter-wave, unity gain, ground

plane antenna:

Rated Power of Recommended Minimum Lateral

DTXM-260-0BS6I Radio Distance from Transmitting Antenna

6 watts 11 inches (28 cm)

Antennas

• Install antennas taking into account the recommended minimum lateral distances listed above.

These antenna installation guidelines are limited to antennas with appropriate ground planes. The

antenna installation should additionally be in accordance with:

a.) The requirements of the antenna manufacturer/supplier.

b.) Instructions in this manual including minimum antenna cable lengths.

c.) Antennas other than those shown in Table 1 must be tested with the DTXM module

for RF exposure compliance in the environment in which it is to be used per the FCC’s

OET Bulletin 65, Edition 97-01 or Industry Canada RSS-102.

• Use only a VHF quarterwave antenna or equivalent antenna or other antennas as described

above. Unauthorized antennas, modifications, or attachments could damage the radio and may

violate FCC regulations.

Approved Accessories

• This radio has been tested and meets the FCC RF exposure guidelines when used with the

Ritron accessories supplied or designated for this product. Use of other accessories may not

ensure compliance with the FCC’s RF exposure guidelines, and may violate FCC regulations.
