Notice
Transmitter should be more than 20cm from Receiver, when the distance is less than
20cm, Receiver’s wireless signal receiving part will take protect action to shut down the
receiving of wireless signal, then audio may be intermittent, which is normal;
When using auto IR sync, please stay within one meter, otherwise the signal may be too
weak and the sync will not be successful;
The antenna will aect the working distance. Please protect the antenna and avoid any
man-made damage;
When using this product in a short distance, it is recommended to set RF strength at
‘LOW’ to reduce the power consumption;
For smartphone shooting, customers need to purchase a TRS-TRRS audio cable;
Do not expose the device in rain or humid environment, otherwise there will be a danger
of short circuit;
