Lift the click lock of the battery compartment and open the weatherproof battery cover. 3. Install 2 pcs of size AAA batteries according to polarity markings at the bottom of the battery compartment. 4. Once batteries are installed, push and hold the ìRESETî button for 3 seconds to send registration signal to the receiving unit. The LCD of the receiving unit will show the current temperature. 5. Once registration is complete, check that the rubber seal is in the cover groove, then close the battery cover tighly. Precautions a. Do not clean the units with abrasive or corrosive compound. It may scratch the plastic parts and corrode the electronic circuits. b. Do not subject the units to excessive force shock, dust, temperature or humidity, which may result in malfunctioning, shorter electronic life span, damage battery and distorted parts. c. Do not tamper with these unitsí internal components. Doing so will invalidate the warranty on the unit and may cause unnecessary damage battery and distorted parts. d. Do not subject the units to excessive exposure to direct sunlight. Although remote has splash proof design. Never immerse it in water or expose it to heavy rain. e. Always read the users manual thoroughly before operating the unit.

Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigate all operating modes, rotated about all 3 axis (X, Y & Z) to obtain worst position, manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarization. The emissions worst-case are shown in Test Results of the following pages. *:OATS [Open Area Test Site] located at HKSTC with a metal ground plane on filed with the FCC pursuant to section 2.948 of the FCC rules, with Registration Number: 90657.
