When using auto IR sync, please stay within one meter, otherwise the signal may be too weak and the sync will not be successful;

In the case of stereo/mono mode switch, please preset the mode before using to avoid the transient interference caused by switching during usage;

The antenna will affect the working distance. Please protect the antenna and avoid any man-made damage;

The working distance will be affected by the surrounding environment. Please try to keep the environment open without interference during usage, and close the WIFI of the device itself;

When using this product in a short distance, it is recommended to set RF strength at ‘LOW’ to reduce the power consumption;

For smart phone shooting, customers must separately purchase a TRS-TRRS audio converting cable,and pay attention to set the mobile phone mode to 'Flight Mode' to avoid incoming call interference;

(It does not support the original recording system of some android systems, the third-party APP is recommended to be used in this case);
