HOW THE EUT MEETS THE REQUIREMENTS OF 15.31 (e)
FOR THE UNIVERSAL ELECTRONICS, INC.
UEI FREESPACE USB DONGLE MODEL: URC-4501BJ0-R-B

The fundamental was maximized on the Lab D test site using a normal test setup with the power
supply of the laptop connected directly to the AC public mains (115 Vac).

Note: The EUT gets its power from the laptop.

Next, the power supply of the laptop was then connected to the Staco Energy Products Variable
Auto Transformer Model: 3PN1010. The Variable Auto Transformer allows the Vac input to be
varied.

The AC input was then dropped to 85% (97.75 Vac) and raised to 115% (132.25 Vac). The actual
AC input was measured using a calibrated Fluke Multimeter Model: 87, Serial Number: 956410240,
Calibration Due Date: May 28, 2010. The fundamental was then verified again to see that the
amplitude did not change.

Test Result: The EUT does NOT change amplitude at the fundamental when the AC input voltage is
varied between 85% and 115% of the input nominal rated supply voltage.
