Radio Frequency Exposure
LIMIT
According to §15.247(i), systems operating under the provisions of this section shall be operated in a
manner that ensures that the public is not exposed to radio frequency energy levels in excess of the
Commission's guidelines. See § 1.1307(b)(1) of this chapter.

Remark:
1. The maximum output power is 29.66dBm (923.90 mW) at 2437 MHz (with numeric 2 antenna gain.)
2. DTS device is not subject to routine RF evaluation; MPE estimate is used to justify the compliance.
3. For mobile or fixed location transmitters, no SAR consideration applied. The maximum power
density is 1.0 mW/cm

even if the calculation indicates that the power density would be larger.
*Note: Simultaneous transmission is not applicable for this EUT.
