Note: Due to structural reasons, the position of the screen is not the center of the screen,
but is offset to the right by about 81mm. This should be taken into account when
determining the location of the mounting hole; in addition, it is recommended to keep a
distance of 1 meter from the side of the screen power cord for future maintenance.

right hanging plates respectively, install M10 screw rods directly above the corresponding
holes to connect the left and right hanging plates, install an adjustable hook on the
middle of the screen to connect the middle hanging plate, and adjust the screws The

If it is really necessary to adjust the limit height due to the installation environment or site limitation,
you can use the motor positioning adjustment key to rotate the knob on the motor limiter; Just
remove the baffle at the power end to find the position of the motor
In order to ensure the accuracy and safety of the screen position, the screen must be raised and lowered
every half circle of the button to check whether the position is moved correctly! Be especially careful
when adjusting the height of the screen recovery. Excessive adjustment will cause the lower rod to jam
into the shell and cause serious consequences such as damage to the screen or falling of the lower rod!
Be careful when adjusting the unfolding height of the curtain. Always keep the curtain wrapped around
the rotating tube with 1.5 turns or more to ensure that the curtain will not fall.
