factory and BATT status mode (main menu).
BATT: battery status, function reset settings
Battery level display. Battery voltage appears on LCD display. When the voltage is 4.4V, the
value flashes and you can hear warning sound. This means the battery voltage is deficient.
When battery voltage value shows 4.0V, the value blinks fast and warning sound keeps strong.
This indicates battery voltage is too low and batteries cannot be used. Please turn off the
transmitter and replace batteries. If rechargeable Ni-Mh or Ni-Cd batteries are used, please
charge the batteries with proper charger.
Function reposition. In case the parameters are messed up or if you don't know how to set
up, please turn off the power, press and hold MENU Left key (<). Then turn on the power and
you will hear “beep” sound after two seconds. Release all keys and all parameters will go back
to factory default values.

frequency might be duplicated. In this case, you may choose the auto frequency function. First
turn off the power, then press and hold MENU Right key (<), and turn on the power. The display
will show hopping data. Release the key and the hopping data will stop. The digit shown on the
display is your frequency. Bind the transmitter with the receiver through binding keys.
