SUGGESTION AND TIPS
In Order To Reach The Best Receiving
Transmitter effective receiving range depend on operation environment and condition. Maybe
in 10 meters or 150 meters.
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.
Multi- Frequency Operation
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.
