RE: Models similarities for Pocket Radars
FCC ID: WZK-PR-1002
Model: SR1100
Attn: Director of Certification
This letter is to confirm the following was considered lor this new FCC application of Pocket Radar device. as
referenced above. Under CFR 47 FCC Part 15.245. the radar device is electrically the same as the previous versron
of our Radar device certified in 2016 under FCC 1D: WZK-PR-1001.
The only difference in the device under certification is Bluetooth 4.0 BLE by Texas Instruments cc2540 has been
turned on in the Pocket Radar device, (refer to colocation test report in this filing). All of the BLE circuitry was already
in place on the previous version, To eliminate susceptibility from interference from the 2.4 GHz Bluetooth radio. six
more small shorting stubs were added to the radar receiver. There was already one present on the earlier board.
These stubs are all set to be a quarter-wavelength long shorted stub at the radar frequency so that they have no
impact on the transmitter. Please refer to the internal photos for details of the circuit board.
To conclude, we feel that there are no significant changes to this device to warrant further testing of the radar device.
Sincerely,
figfl/wfl
