RF Exposure Compliance and Control Guidelines and Operating Instructions
To control exposure to yourself and others and ensure compliance with the Occupational/
Controlled environment exposure limits always adhere to the following procedures.
Guidelines:
User awareness instructions should accompany the 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), push the
Push-To-Talk button. To receive calls, release the PTT button. 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 outside the vehicle are at least the recommended minimum lateral
distance away, as shown in Tables 1 and 2, from a properly installed according to installation
instructions, externally-mounted antenna.
NOTE- Table 1a) lists the recommended minimum lateral distance for bystanders in an
uncontrolled environment from the transmitting antenna for the SRM9000AC (136MHz-
174MHz) mobile rated power (25 watts) installed in a vehicle. Table 1b) lists the
recommended minimum lateral distance for occupational/ controlled use.
Table 2a) lists the recommended minimum lateral distance for bystanders in an uncontrolled
environment from the transmitting antenna for the SRM9000UW (440MHz-520MHz) mobile
rated power (25 watts) installed in a vehicle. Table 2b) lists the recommended minimum
lateral distance for occupational/ controlled use.
