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 (150MHz-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-512MHz) mobile rated
power (25 watts) installed in a vehicle. Table 2b) lists the recommended minimum lateral distance for
occupational/ controlled use.
