Wireless Barbecue Thermometer includes a Receiver that receives the temperature signal from a
Transmitter using two stainless steel probes to detect meat or barbecue chamber temperatures.
A. Transmitter unit (MAV238)
The transmitter unit displays the measured temperatures and sends it to receiver unit
Features and specifications:
1. LCD Display
a. 1-line LCD display toggles the measured food / barbecue temperatures from two channels
(probes).
b. Uses probe to measure meat or oven temperature. (See accessory section for the selected
probe type).
c. Displayed Temperature unit is ˚F / ˚C, user selectable. Default
temperature unit is ˚F. Optional design on PCB to allow the
change of default temperature unit to ˚C.
d. Antenna icon shall show up when the unit is transmitting RF
data to receiver unit.
e. Battery Low indication: LCD displays “Lo” on most right two
digits for 2 seconds and probe temperature reading (3 seconds
each)alternatively when the battery low level is detected.E.g.
T1(if any) → “Lo” → T2(if any) → “Lo”and then repeat.

2. LED light up when the unit is transmitting RF data to receiver unit.
3. Probe sockets
a. Equipped with 2 probes Max.
b. Both probe wires can resist temperature up to 716˚F / 380˚C is specification of the wire
only.Temperature sensor with maximum 300˚C is used inside the probes.Temperature
above 572˚F (300˚C) will not be displayed properly as this is the temperature limits of the
sensors.
NB: Temperature sensor inside the probe might be damaged if the probe is exposed to
temperature above 572˚F (300˚C) for a long time.
4. RF link Re-Sync / ˚F↔˚C
a. Press and hold the button for 2 sec will re-synchronize with the Receiver unit if there was a
loss link.
The Transmitter and Receiver shall be linked in pair before Ex-factory. In normal case
the user does not require to pair the unit even though the battery is replaced.Unless the
user purposely wants to pair the Receiver to another Transmitter, or ID lost on Receiver
due to whatever reasons, user may follow the pairing procedure to link the Transmitter
and wanted Receiverin pair again. (refer to user guide for pairing procedure in detail)
see receiver section 2C for Rx pairing procedure.
b. Short press the button will select displayed Temperature unit ˚F / ˚C.
5. Power button – Press and hold for 2 sec to turn ON or OFF of the unit.
6. Equipped with Wire Stand to let the transmitter stand on desktop or it can be reversed as a
hanger.
7. Low Battery detection: 2.70V +0.15 / -0.1V
8. Power: DC 3V (2 x AAA size Batteries)
9. Water-resistanthousing design IPx4.O-ring is applied to the battery compartments for water
resistant.
10. Specifications (Transmitter):
a. Temperature measurement range:32°Fto 572°F (0˚Cto +300˚C).
i. If temperature below 32˚F (0˚C), “LLL” will be displayed.
ii. If temperature above 572˚F (300˚C), “HHH” will be displayed.
b. Temperature reading resolution: 1°F (1˚C)

c. RF center frequency: 433.92MHz
d. Operating Distance >500ft (150m) line of sight.
e. Wireless data transmission interval:12 seconds.
f. Data modulation scheme: GFSK
g. Operating Voltage = 2.6V – 3.3V
h. Battery life ≥ 12 months
i. Operating Environments:
Temperature = 32to122 °F (0to50°C)
