Notice
Due to 2.4G wireless characteristics, please keep face to face when use it, and don’t turn your back to the
receiver, otherwise it is easy to generate breakpoints, which is a normal phenomenon
Don't block the antenna position to avoid any poor signal generated
Please attention that it can not realize STEREO function when in one-trigger-one mode
3.5mm TRS-TRS Audio Cable is suitable for Canon, Nikon and other cameras with low sensitivity
3.5mm TRS-TRS Audio Output Cable with Impedance is suitable for Sony, Panasonic, Fujifilm and other cameras
with high sensitivity(3.5mm TRS-TRS Audio Output Cable with Impedance is recommended to be used if there is
sound explosive in recording )
When using on mobile phone, please turn off WIFI and Bluetooth to avoid 2.4G wireless interference
This product belongs to high-precision instruments, please avoid falling, collision or pounding
Do not use this equipment in the vicinity of heat source or interference source, such as radiator, oven, refrigerator
