DIGITAL THERMO SENSOR (MODEL NO. W044) OWNER'S MANUAL Thank you for purchasing the new generation electronic thermo sensor. Designed and engineered with the state-of-art technology and components, this instrument will provide accurate and reliable measurement of outdoor temperature and humidity, and a 433MHz RF communication with your weather station. Read this manual carefully to full explore the features and functions of the new product. Name and Functions of Switch and Buttons: CH Select Channel 1,2,3 TX Force transmission of RF signal C/F Select the reading between C and F BATTERY INSTALLATION Lift off the bracket stand, loose the 4 screws with a small screwdriver, insert 2 pcs AAA batteries according to the polarity indicated. Replace the cover and tighten the 4 screws. SETTING UP THE WIRELESS THERMOMETER: • For the first installation, always insert batteries to the home unit and then the remote sensor. • Set Channel 1 for the first remote sensor. Set channel 2 and channel 3 for the additional 2nd and 3rd sensors. • Press the Tx button on the back of remote sensor to verify the RF reception. C/ F SELECTION Press “C/F“ to select degree C/ degree F on the LCD display. LOW BATTERY INDICATION Low battery indication is available for the remote sensors. Replace the batteries and follow the setup procedure as mentioned in this instruction manual if the low battery indicator is shown. BATTERY DISPOSAL Replace only with the same or equivalent type recommended by the manufacturer. Please disposal of old, defective batteries in an environmentally friendly manner in accordance with the relevant legislation. NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user authority to operate the equipment NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. SPECIFICATIONS Range of temperature measurement: Remote sensor : -20 C to +60 C (-4 F to +140 F) Channel : 3 Transmission : up to 30M (100 ft.) open area, RF434 MHz Resolution : 0.1 degree for temperature, 1% for humidity Batteries : AAA x 2 pcs

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. *: On a standard radiated emission 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 / 607756. Test Setup: EUT distance = 3m Pre -Amplifier Receiver Turn Table Computer Ground plane

Application No.: HM156767 Date: 21 June 2006 FCC ID: L5CW044TX-F Circuit Description The 434.02 MHz crystal oscillator drives the base of Q2 the final/buffer amplifier. The modulation provided by IC. The output of Q2 has the matching network consisting of L6 and C1 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source There is no external antenna. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3 Volt (“AAA” size battery x 2) primary battery. Operation Descriptions The transmitter is a RF wireless thermo-hygro operating at 434MHz band. The transmitter is powered by a 3V battery (“AAA” size battery x 2) and the transmitting frequency is crystal controlled. The operation is achieved by different combinations of form pulse modulating signal on the 434MHz carrier frequency. Remarks: The transmitter is a Trigger transmitter. The EUT continues to transmit while Trigger is being pressed. It is Pulse transmitter, Modulation by Data Code; and type is Pulse modulation.
