2.3. Description and Method of Exercising the EUT
The JBL Radial Micro is an Speaker System. Its function is play music from an Apple IPOD or another
digital music source. The EUT was exercised by playing pink noise (track name: EIA Noise 250 sec -15dB
stereo) stored in the IPOD with volume set to maximum via the included remote control. It fails by not
answering remote control commands or skipping mode during immunity tests or inability to amplify music
inputs.
