1、Setting barcode are made by Code128-type B.
2、The part with “*” means factory default settings.
（1）Scanning：After scanning the barcode “@SET” to enter setting mode, if not within 20 seconds
scanning the next setting command , exit setting mode automatically
（2）In setting mode ,can scan . Scanning: related set of barcode. In this step, the bar code command can
4 / 27
scan one or more Settings
（3）Scanning：scan “@END”.
（4）Some functions can be set directly. such as “pairing”, “discharge pairing”

Notice☆:1. For the setting of the non-quick setting command, it is necessary to scan into the setting
command first, and then scan the corresponding parameter setting instruction and finally
scan the saving and exit setting instruction.
3. If in setting state, scanned the setting bar code, the system will identify as invalid barcode, low sound
alarm, invalid alarm belongs to the normal situation.
4. To set the type of barcode
4.1 Pairing ★

/ Discharge pairing
Notice☆:1、The pairing effective time is 20 seconds from the start of the receiver's power-on (the LED is
flashing). After 20s, the LEDs are always on and cannot be paired. (This method is for a
receiver without a button)
2、Press buttons on the receiver, the receiver will automatically enter the matching state, during
this period can be paired normally. (with button this way for receiving).
3、 2.4G stops flashing after pairing is successful, and 433 stops flashing after 20S is turned on.
