Circuit Description The 24MHz crystal oscillator drives the base of Y2. The modulation provided by AC6969A. The output of AC6969A module (U1) has the matching network consisting of L1、L2 and L3 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source The antenna consists of a 2.4GHz Onboard antenna There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3.7 Volt primary battery Feature: Frequency Range: 2402MHz-2480MHz Modulation Type: Bluetooth: GFSK, π/4-DQPSK, 8DPSK; BLE 1M: GFSK Antenna Type: Onboard antenna Crystal: 24MHz

Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. Measurement Result For worst case: Frequency (MHz) Maximum Tune-up power # Calculated Distance (mm) Calculated Value Threshold (1-g SAR) SAR Test Exclusion (dBm) (mW) 2402-2480 4.5 2.82 5 0.9 3 Yes Note#: the maximum tune up power was declared by the applicant. Result: No Standalone SAR test is required
