RF exposure information

FCC ID: XUJPADIVHD
Product name: Heavy duty/Medium duty/Light duty Vehicle Communication
Interface
Models names: HD IV

1. Introduction:
This product is Heavy duty/Medium duty/Light duty Vehicle Communication Interface
with Bluetooth (2402~2480MHz) function.

2. Output power considerations:
Worst case output power: 3.364dBm = 2.170mW (at 2480MHz)

3. Compliance criteria:
According to 447498 D01 General RF Exposure Guidance v05 the 1-g and 10-g SAR
test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm
are determined by:
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation
distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR,
Where:
f(GHz) is the RF channel transmit frequency in GHz
Power and distance are rounded to the nearest mW and mm before calculation

Calculate:

(2.170/5) * √(2.48) = 0.683 < 3 for 1-g SAR

Then SAR evaluation is not required.
