While in Normal Mode, please press and hold the CHANNEL/+ button for three seconds until you hear the ticking sound and all the data show dashes.

The display will re-receive the signal from the transmitter. Once the signal

is reacquired, all the data will be displayed.

You can also reset the transmitter.

After the transmitter is powered on, if the indicator light blinks every 16 seconds it means the outdoor unit is working properly.

After the transmitter is powered on and working properly, the display has

to be re-plugged in to re-receive the transmitter signal. It usually takes 1-3 minutes to receive the data, do not operate the keys or power off until the

transmitter data is received.

1. Please remove the batteries of the transmitter and the display.

2. Please unplug the display from the power supply.

3. Please put batteries in the transmitter.

4. Please plug in the power of the display.

5. Please put the batteries in the display after the display lights up and the data show dashes.

Also, you can replace the batteries in the transmitter with new ones.
