Before You Begin To ensure proper functioning of the RF Thermo Clock, please follow this set up procedure. • Insert batteries for main unit ( Refer to instructions for battery installation ). • Place the main unit as close as possible next to the remote unit and insert batteries for the remote unit. • Position the remote unit and main unit within effective transmission range, which in usual circumstances is 20 to 30 meters. Note that the effective range is affected by the building materials and where the main and remote unit are positioned. Try various setup for the best results. Batteries Installation Batteries installation of the clock • Insert 2 "AA" batteries in polarity (+) and (-) as indicated • Close the battery cover • The low battery icon will show in the clock window when your batteries need replacing Batteries installation of wireless transmitter • Insert new batteries into transmitter • Insert 2 "AA" size batteries in proper polarity (+) and (-) as indicated • Close the battery door Warning : Do not mix old and new batteries Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel cadmium) batteries. Do not touch any other buttons or settings on your clock. It will automatically receive the remote temperature.

The clock attempts to receive the RF temperature signal for 5 minutes. The clock refreshes the RF temperature every 3 minutes. Check IN / REMOTE Temperature The indoor temperature is displayed on the IN temperature field and the remote temperature will be displayed on the REMOTE temperature field. If the RF temperature signal is not received within 5 minutes after power up of the receiver (or pressing the reset button), blank "---" will appear in the outdoor temperature window of the clock. In this case, press the HR/SYNC button of the clock. The clock will attempt outdoor temperature reception for another 6 minutes. After the remote temperature shows in the lower LCD panel, place the remote transmitter outside in a shaded, dry area to protect it as if under an umbrella. Try relocating the clock or the transmitter if the clock does not display the outdoor temperature after 6 minutes. Maximum and Minimum IN / REMOTE Temperature The maximum and minimum recorded temperature readings will automatically be stored in the memory. Press the Max/Min button once to display the INDOOR maximum and minimum record. Press the button again to show the REMOTE maximum and minimum record. The respective indicators, IN and REMOTE will be displayed. To clear the memory, press CLEAR when the maximum and minimum temperature records are shown, it will clear the record of the shown temperature field. To Set Calendar Press SET one time, upper LCD show year "2002" and blinks. Press + or - button to set year. Press and hold + or - will accelerate setting in faster speed. Press SET again, upper LCD changes to 1 M 1 D and blinks, press + or - button to set month and date. Press and hold + or - will accelerate setting in faster speed. To Set Time Press SET again, time digits blink, press + or - button to set time in minutes. Press and hold + or - will accelerate setting in faster speed. To Set 12HR / 24 HR Time Format Press SET again, upper LCD shows 12H and blink, press + or - button to select 12H or 24H. Press SET again to go back to current time display or if no button is further pressed for few minutes, the clock will go back to normal time display automatically. To Set Daily Alarm Time When the clock is at normal time display, press + or - to set your desired alarm time. Press and hold + or - will accelerate setting in faster speed. To Activate Alarm Function 1. Slide the SNZ/ALARM ON/OFF switch to ON position, the sign will appear on the time display. The alarm function is activated. 2. When the alarm sounds, press the Snooze/Light button. The alarm will sound the same time of the next day. 3. To deactivate the alarm function, slide the SNZ/ALARM ON/OFF switch to OFF position. To Activate the snooze alarm 1. Slide the SNZ/ALARM ON/OFF switch to SNZ position. The sign and Zz will appear on the time display. 2. When the alarm sounds, press the Snooze/Light button. The alarm will sound again in approximately 5 minutes. You may repeat this function for 10 minutes. 3. To deactivate the snooze alarm, slide the SNZ/ALARM ON/OFF switch to the OFF position. Cen…

Technical Description of the Circuit: The circuit is a RF thermometer transmitter part, the MCU TM8712 will measure the temperature and code the data. Afterward, the data is transferred to the RF circuit which is a SAW stabilized Colpitts Oscillator ( Constructed by Q1, L1, L2, C1, C2, C3, C4, C5, R1, R3 and X1 ) every 3 minutes, when the Data pin output HIGH level to the oscillator, the oscillator is turned on and output 433.9MHz RF signal, when the Data pin output LOW level to the oscillator, the oscillator is turned off and this ON & OFF process modulate the code data into 433.9MHz with ON OFF KEYING.. Also there is an antenna matching network ( Constructed by C7, C8, L3 and L4 ) after the SAW stabilized Colpitts Oscillator, this network suppress harmonic and spurious also match the Oscillator to the antenna.
