Ewig Industries Co LtdSmoker thermometer Prepared By: Tony WuDated: March 26, 2003 1 OPERATION MANUAL Ideal for smoking, our remote thermometer allows you to monitor cooking progress from up to 100 feet away. Before using the remote thermometer, please read the Essential Safety Information. Inside this package, you will find: 1. Receiving unit (1) 2. Transmitter unit (1) 3. Detachable 3 feet stainless steel probe sensor and wire for food temperature measurement (1) 4. Detachable 2 feet stainless steel probe sensor and wire for smoker air temperature measurement (1) 5. AAA batteries (4) (Super Heavy Duty) Receiver Features: LCD (Liquid Crystal Display): This screen shows all icons, temperature readings and time displays. CLIP: The removable clip allows you to attach the receiver to you apron or belt, so you can keep the unit with you as you move around the house or yard. STAND: The sing-out stand allows you to stand the receiver on a counter or tabletop.

METAL HOOK for hanging, or reversed to use as a stand BATTERY COMPARTMENT: Holds 2 AAA batteries PLUG IN JACK for stainless steel FOOD probe sensor PLUG IN JACK for stainless steel SMOKER probe sensor Functions of Buttons on the Transmitter: 1. TX: Before first use, press and hold to register radio frequency with Receiver (see “Getting Started” below). 2. ON/OFF: Turn the transmitter unit on or off. Installing Batteries Make sure both receiver and transmitter units have the ON/OFF switch set to OFF. Open the battery compartments on the receiver and transmitter. Insert two AAA batteries into each compartment. Getting Started Before first use, you’ll need to set the receiver to register the radio frequency signal from the transmitter. This is called the “registration procedure”. 1. Plug the stainless steel probe sensors into the plug-in jacks on the transmitter matching the FOOD and SMOKER markings. 2. Using the ON/OFF switches, first turn on the receiver (ON/OFF switch at back) (display shows “- - - “ blinking). Then turn on the transmitter (ON/OFF switch inside battery compartment – which can be open using a coin). 3. The registration procedure is complete when the receiver beeps and the LCD displays the current temperatures for both smoker and food (provided both probes are inserted) If the registration procedure fails, the readings will show “- - - “ steady. Use ON/OFF switch to reset the receiver, and press the TX button (located on the rear of the transmitter) and hold for 2 seconds. This needs to be done within 60 seconds of turning the receiver on in order for the receiver to register the signal from the transmitter. Once TX is released. It will take several seconds for the receiver to register. If you don’t hear a beep within 5-10 seconds, press and hold TX again. Cooking According to Settings Our remote thermometer features programmable cooking temperature settings for foods safety. The temperatures displayed to the left of the LCD screen will show the set temperatures. To show and set maximum and minimum smoker temperature 1. Hold Light/MODE button to select smoker mode. The lower display will show a small SMOKER icon and temperature reading Ewig Industries Co LtdSmoker thermometer Prepared By: Tony WuDated: March 26, 2003 3 2. Press SMOKER-HI/HR or SMOKER-LO/MIN. The lower display will show a small HI icon (or LO icon) and the set maximum (or minimum) temperature for the smoker (automatically exit after 5 seconds) 3. Hold SMOKER-HI/HR (or SMOKER-LO/MIN) to enter setting mode (display flashing) 4. Press SMOKER-HI/HR (or SMOKER-LO/MIN) repeatedly to set the desired temperature (hold to fast forward) 5. Press MODE to confirm and return to normal mode To show and set max food temperature 1. Press FOOD-HI/CLEAR. The upper display will show a small HI icon and the set maximum temperature for the food (automatically exit after 5 seconds). 2. Hold FOOD-HI/CLEAR to enter setting mode (display flashing ) 3. Press FOOD-HI/CLEAR repeatedly to set the desired temperature (hold to fast forward) 4. Press MODE to confirm and return to normal mode To turn on the temperature alarm 1. Press Alert/ START/STOP to activate the temperature alarms for Smoker and Food. The alarm icons will be on at the upper and lower display. 2. For smoker cooking, insert the FOOD probe into the thickest part of the meat, place meat in the smoker and close the door. Make sure the probe is not touching a bone or any heavy fat areas. 3. The receiver will beep continuously, and the alarm icon and probe temperature display will blink when one of the following conditions happens: When the actual food temperature reached and exceeded the maximum FOOD set temperature, & When the actual smoker temperature reached and exceeded the maximum SMOKER set temperature, or fell below the minimum SMOKER set temperature. Note: The SMOKER – LO alarm will not happen if the first temperature reading is originally lower than the SMOKER set minimum temperature. 4. Press the Alert/ START/STOP to de-activate the alarm. Using the Timer Function The minimum setting for the timer is 1 minute, and the maximum setting is 24 hours. Times less than 10 hours are di…

FCC ID: N9Z693200 Circuit Description The 433MHz crystal oscillator drives the base of Q8 the final/buffer amplifier. The modulation provided by IC (W74IC260). The output of Q8 has the matching network consisting of L6 and C25 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
