When transmitter closed or transmitting power not high enough ,
Squelch can restrain noise . Squelch setting should be ensure
the receiver don’t have a big noise when turn off transmitter .
When receiving environment is bad , higher squelch setting will
be reduce receiving range.
Closed squelch or setting squelch too low will be causing big noise.
High noise will damage hearing and overload loudspeaker.
Be Careful To Damage Hearing And Equipment !
Ensure squelch keep turning on.
Ensure AF output level adjust to be lowest before setting squelch.
Not allow to change squelch during transfer.

In Order To Reach The Best Receiving
SUGGESTION AND TIPS
Transmitter effective receiving range depend on operation environment and condition. Maybe
in 10 meters or 150 meters.
Multi- Frequency Operation
When receiving condition is not good , receiver should connecting two separate antenna by the
antenna cables.
Receiver and transmitter should be keep at least 5 meters distance which can avoid wireless
signal of receiver over modulation.
Receiving antenna should keep at least 50cm distance with steel plate or wall and adjust the
antenna with V shape.
Every channel from A to J all including anti-interference pre-set frequency (fixed frequency ).
Select the available frequency from frequency data (factory frequency range ).
Setting frequency between 1 to 14 in frequency range (check page 10).
Each transmitter should keep at least 20 meters distance to avoid transmit interference.
Please using ENBAO recommended multi-frequency equipment application.

18
Receiver And Transmitter Sync Connection Method
Step1: Turn on receiver , keep closing transmitter.
Step2:Select one channel in main interface, press rotary button to confirm selection.
Step3:Long press transmitter power switch button and short press receiver W.Sync button.
Receiver will display Sync that means connecting , then transmitter indicator light keep lighting
that means connecting successfully
Step 4: Others channels can follow above steps to finish connection.
SYNC METHOD
Setting Frequency
Step1:Turn on receiver and all transmitters.
Step2:Long-press W.sync button in the receiver , receiver display sync connecting (such as
page 12), after connection , transmitter indicator keep lighting that means sync connecting
successfully.
