HOW THE EUT MEETS THE REQUIREMENTS OF 15.31 (e)
FOR THE UNIVERSAL ELECTRONICS, INC.
COMCASE XR8 RF4CE SERIAL DONGLE 2012, MODEL: URC-4868BC0-R

The fundamental was maximized on the Lab B test site using a normal test setup with the Set Top
Box that the EUT was connected to being connected to the AC public mains (115 Vac).

Next, the AC power for the Set Top Box was 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: 58450372,
Calibration Due Date: June 3, 2014. 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.
