Press MEAT button for selecting the types of meat : Beef, Burger, Lamb, Veal, Pork, Chicken, Turkey, Fish, Duck or Other 5. Press TASTE button for selecting the cooking status of the meat : Welldone, Medium, Medium Rare, Rare >> The TARGET temperature will be changed on the bottom left 6. Press the START button on top of the receiver. When the temperature at Probe 1 or Probe 2 reaches the 5 degree below the optimal temperature, it will transmit the data to the receiver. In return, the receiver will announce a short beeping sound. When the temperature reaches 30 seconds or 5 degree celcius of the optimal temperature, the receiver will announce short beep of 2 times and then when the temperature reaches the optimal temperature, it will announce a long beeping sound with flashing from the LCD. 7. Press the SOUND button to turn off the beeping sound. l User can test the function of the data transmission by pressing the Test button (located inside the battery compartment) l User can switch the temperature to Fahrenheit / Celcius switch (located inside the battery compartment) l User can switch the ID so that there is no interference of for other users within the same atmosphere. l Out of Range – when the receiver is out of range over 120’ (40 m) eye of sight, it will alert the user with a short beep every 4 seconds.
