Manual draft for MAV210 Page 3 of 7 Low battery indicator for transmitter base In thermometer mode, the main unit displays the food temperature measured by the remote sensor and prompts the user about the cooking level. The user firstly selects a food type (e.g. Turkey) and a cooking level (e.g. Well done). The main display unit will automatically set the target temperature (170 °F). When the food temperature is within 10°F of the target temperature (e.g. 160°F), the main unit will beep twice and voice prompt; “ Your food is almost ready”. The unit will repeat the above two beeps and the voice after 4 seconds silence. When the food temperature reaches the target temperature, the main unit will beep 3 times and voice prompt; “Your food is ready”; The unit will repeat the above three beeps and the voice at 30 second interval for 10 minutes. The alert icon will blink simultaneously. The user can press [STOP] button to stop the voice. When unit has not received any valid data from the linked transmitter base for more than 1 minute, the RED LED will blink at 1Hz and the speaker beep once every 3 seconds to prompt the user for a RF loss link. In order to re-link up the transmitter and the receiver, the user must get the transmitter base close to the receiver and make sure not iron obstacle between them to block the RF signal. Displayed food temperature range: -10°C to +250°C (+14°F to +482°F) Displayed temperature resolution : 1°C (2°F) Low battery indicator for receiver Manual draft for MAV210 Page 4 of 7 Transmitter Features BATTERY COMPARTMENT – holds 2 AA batteries.
