Min Max
Low 138 MHz 153 MHz 25 kHz 600
Mid 154 MHz 162 MHz 5 kHz 1600
High 162 MHz 174 MHz 6.25 kHz 1920
Channel to Frequency Calculation
Channel * Channel Step + Min Frequency = Frequency for Channel
Examples:
- Low Band Channel 20
- 20 * 0.025 +138 =138.5 MHz
- Mid Band Channel 300
- 300 * 0.005 + 154 = 155.5 MHz
Frequency to Channel Calculation
(Frequency – Min Frequency) / Channel Step = Channel for Frequency
Examples:
- Low Band 151.5 MHz
- (151.5 – 138) / 0.025 = Channel 540
- High Band 172.5 MHz
- (172.5 – 162) / 0.00625 = Channel 1680
Section 6: FCC RF Exposure Limits
This device complies with the MPE requirements by providing a safe separation distance of 30 cm
between the antenna, including any radiating structure, and any persons when normally operated.
CAUTION:
The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter. This device is approved with emissions having a source-based time-
averaging duty factor not exceeding 50%.
Operating at a lower duty cycle than 50% will allow proportionately shorter exposure distance than
30 cm.
