EUT Description
Model: DD-005
Description: Battery Powered, wireless positioning and duress alarm for prison guards
Firmware: NA
Software: NA
Serial Number: NA
Additional Information:
Unit is incorporating Bluetooth Low Energy technology with frequency range of 2402-2480 MHz.
For Conducted testing an unassembled device with RF connector was utilized and it was powered up with
DC power supply of 6.0 V. The regular radiated emissions test device work with batteries


EUT Operation during Tests
The production sample of Model DD-005 transmits once every second on 3 channels, with each
transmission taking 184µsec, or 0.000184 seconds. Total transmission time, on each channel, per
second is 184µsec or 0.000184 seconds. This results in a duty cycle of 0.018%.

Calculating SAR exclusion per KDB 447498.


1) 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,25 where

• f(GHz) is the RF channel transmit frequency in GHz
• Power and distance are rounded to the nearest mW and mm before calculation26
• The result is rounded to one decimal place for comparison
• 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below

Per formula above:

0.101 𝑚𝑊
           X√2.402 = 0.031306742
 5 𝑚𝑚


This unit is exempt from SAR testing.
