  powered on.

• SETUP Button: Enter joystick calibration mode after the radio
  transmitter is powered on.

2. Power On/Off

To power on the radio controller:

1. Long press the power button on the radio controller for 3
   seconds until it beeps three times (do re mi) then release.

2. The LED ring will turn red quickly, then remain blue.

4. Binding the Receiver

To bind the LiteRadio 2 SE with a receiver:

1. Power on the remote control radio transmitter and wait for its
   system to load completely. LED ring is solid blue.

2. Enter the receiver’s binding mode and wait for it to bind with
   the radio.

3. Press the bind button on the back of the transmitter to enter
   binding status. The LED ring will be red.

4. The LED ring will change to solid blue 5 seconds later when the
   transmitter exits binding status. If not bind successfully, repeat
   the process above.

5. Switching Protocol

Note: Switching protocol is only available for CC2500 version
radio transmitter. ExpressLRS version or Bayang version are
different protocols.

The CC2500 version supports different protocols, including Frsky
D16 FCC, Frsky D16 LBT, Frsky D8, and Futaba S-FHSS. The protocol
is indicated by the flashes of the red LED when powered on, before
the buzzer alarms.

To change protocols:

1. Power the radio transmitter on.

2. Press and hold the BIND button while powering the radio
   transmitter back on.

3. The flashes of the red LED before the buzzer alarms will
   change, according to the tables above.

Note: LiteRadio 2 SE only works with D16 ACCST 1.X Frsky
protocol. So if you use a Frsky receiver with D16 ACCST 2.X version
or ACCESS version, binding will fail.

6. Charging

The remote control radio transmitter has a built-in 1000mAh
battery.

FCC SAR STATEMENT
­This radio is designed for and classified as “General population/uncontrolled Use”, the guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons regardless of age or health.The exposure standard for wireless radio employs a unit of measurement known as the Specific Absorption Rate, or SAR, the SAR limit set 1.6W/kg. ­Body-worn operation; this device was tested for typical body-worn operations with the Front of the Transmitter kept 0mm for body worn. To maintain compliance with RF exposure requirements, use accessories that maintain a 0mm for body worn. The use of belt clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with RF exposure requirements, and should be avoided. ­The highest reported SAR value for worn on the body is 0.672 W/kg .

The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction
