4.3 Alarm for the Failed Paring of Receiver and Transmitter
This wireless product can reach over 300 meters in the open distance. If
the receiver is out of range, with unusual external interference or turn off
the transmitter, the receiver may not be able to receive the data from the
transmitter. If this happens for over 1 minutes, the unit will alert you the
signal is lost by beep. Move the receiver closer to the transmitter, there
will be automatically reconnected and displays the current temperature
on the receiver.
4.4 Alarm for the Low Voltage of Receiver and Transmitter

4.1 Turn On/Off Setting
Press and hold the button on the receiver to turn on/off the receiver.
Press and hold the button /°C/°F on the transmitter to turn on/off the
transmitter.
4.2 Synchronize/Pair Transmitter and Receiver
Usually the transmitter and receiver needn't to be re-paired and
re-synchronized. For the reason we already have paired at our
manufacturing facility. Only need to plug in the probes, insert batteries, turn
on the receiver and the transmitter and wait for a few seconds, you will see
the temperature shown on both receiver and transmitter and the units are
ready to use.
However, in some unusual cases, you may need to re-synchronize and
re-pair by the following steps if the receiver and the transmitter haven't
paired.
1.The transmitter needs to re-install the battery. Then the transmitter will
enter the situation of synchronizing and the temperature display screen
will flicker at the rate of 1Hz if press the button of /°C/°F for 2 times
within 1 second.( After re-install the battery, users had better finish the
synchronize process within 10 seconds)
2.Press and hold the button SET/ST/SP and MEAT/CLEAR of the receiver
for 2-3 seconds to enter the synchronization mode. The CURRENT TEMP
shows “- - -” and keeps flashing.
3.Press the button /°C/°F of transmitter to send signal. Then waiting for
a moment, the receiver will display the temperature if the synchronization/
pairing complete. The receiver will be exit the paring mode after 60
seconds if the receiver did not get any statistics from the transmitter.
Note: The receiver and the transmitter should be put in a close distance
(within 60cm) when doing synchronization/pairing.

6. When countdown timer reaches 0:00, alarm will sound (beep 3 times in
0.5 second, stop in 0.5 second) and backlight will be on for one minute.
5. Help Hints
1. If the receiver and/or the transmitter display LLL or HHH instead of the
probe temperature, wait for probe to reach room temperature. If LLL or HHH
is still displayed or you get a false temperature, squeeze the probe jacks
harder into the transmitter and twist them back and forth so they make good
contact. If the problem is still persists, it is likely the internal probe wire has
been damaged by the moisture or heat temperature.
2. The probe and cable cannot be touched by the flame.
3. If the temperature displayed seems to read too high or the temperature
seems to increase too quickly, check to make sure the probe tip is not poking
through the food. Reposition the probe tip in the center of the thickest part of
food. Avoid touching bone or heavy fat areas.
4. Always wear the heart resistant gloves when you clearing and using the
probes. And do not to touch the probe or cable immediately just after cooking
to prevent burns or puncture.
5. Keep away probes from children.
6. The probes should be cleared well and dry out after used.
