Regarding the issue of upgrading a single remote control to operate up to 999 devices?

The number of lifters controllable by the company's dedicated lifter remote control has been upgraded as follows: a single remote control can control up to 999 lifters, with an unobstructed remote control distance of 100 meters.

Instructions for using the remote control are as follows:

1) Open the rear cover at the bottom of the remote control and insert 2 AAA batteries into the device.

2) Wait until the startup interface is displayed on the screen, then enter the corresponding number based on the code of the target lifter. First press the Cancel button: when the digits on the screen start flashing, press the Confirm button, and the digits will stop flashing.

3) Press the Down button ↓ or Up button ↑ to perform the corresponding operation on the target lifter. Press the Stop button to immediately halt the lifting movement if required.

4) To save an operation position, lower the lifter to the desired position in one continuous movement, then press the Save button to store the position. In subsequent operations, when the Down button is pressed, the lifter will automatically stop once it reaches the saved position.

5) Additional notes: After the lifter stops at the saved position, press and hold the Down button for 3 seconds to force a further descent if required. After pressing the Stop button, press and hold the Cancel button for 5 seconds to clear the saved position.

6) When entering a new device code: after pressing the Cancel button and the digits on the screen start flashing, enter the new code and press the Confirm button to activate the operation.

7) After completing all operations, press the Cancel button to exit the current page. The remote control will automatically shut down after default 5 minutes of standby.

8) To reuse the remote control, press and hold the Power button for 5 seconds to turn it on, and the startup interface will be displayed on the screen.

Notes for use:

1) After pressing the Down button to initiate a descent, you must press the Stop button before pressing the Up button to initiate an ascent; direct operation of the Up button is prohibited. The same rule applies when the lifter is ascending: direct operation of the Down button is prohibited.

2) When the screen of the remote control dims, replace the battery in time to avoid poor signal reception during operation.

3) Position saving is only valid when performed after the lifter descends from the top position and the Stop button is pressed.

4) Do not mix old and new batteries, or batteries of different types.

5) Remove the battery from the remote control if it will not be used for a long period of time to prevent battery leakage from damaging the device.
