a). Tighten the clamp firmly, or the monitor stand will be shaky. For future use, don't discard the supplied Allen Key or other small parts that come with the package - store them properly.

b). The weight and size of the monitor SHOULD NOT exceed the maximum limits as found in the manual, or the arm can't support it.

c). To correctly install the screws, select one that best fits the mounting holes of the monitor arm. Neither too shallow nor too deep, or it may cause damage to the monitor arm. Besides, ensure the screw is threaded properly into the hole.

The monitor arm will bounce and move if the spring tension is not suitable. Once the monitor arm drops, turn the adjustment screw clockwise with the Allen Key, while if it raises, turn the screw counter-clockwise until it can stay in a horizontal position.

P.S. (For LDT14 & LDT45) DO NOT loosen the two screws located on the upper arm as damage may occur to the product.

The monitor arm will bounce and move if the spring tension is not suitable. To solve this problem, firmly hold the monitor arm horizontally and position the arm.

DO NOT hang anything on the handle, which should only be used to position the monitors to a comfortable viewing angle.

a). Monitor arm joints are loose.

Tighten the bolts clockwise with the Allen Key.

b). Monitor arms drop down from the pole.

Tighten the screws clockwise with Allen Key.

c). Monitors drift forward or backward.

When using a multi-monitor arm stand, keep the monitors in the safe desktop area so that they won't fall forward or backward.

b). The system may be overheating. (PLB Series not included)

Check if the unit beeps four times after pressing the button. If so, allow the unit to cool down and return to room temperature. (about 30 minutes)

c). The AC/DC end of the power cord may be unplugged/disconnect from the outlet/mount.

Check the connection to ensure the unit has power.

d). Incorrect operation.

Check if the unit beeps once after pressing the button. If so, please follow the instructions found in the manual to properly operate the mount.

2. Remote Control

a). The remote-control operating distance maybe too far or not in range of the mount.

Acceptable range should be less than 30 feet (10m).

b). The batteries in the remote control may be low or dead.

Replace the batteries.

c). The remote control may be broken.

Check to see if the indicator LED found on the remote lights when a button is pressed. If not, contact your place of purchase for a replacement.

1. Memory Setting

After adjusting the mount to desired height and angle, press the "" or "" button for 1 second and you will hear a beep, indicating that the current position has been saved to memory. The "" and
"" buttons can each store a different position.

2. Recall Memory

Press the "" or "" button and the mount will automatically get to the position saved in the corresponding button "" or "".

To solve some problems of motorized products, resetting the system is a common method.

Press and hold the "" button for 3~5 seconds. Mount will move and stop at the highest position (for wall&ceiling mounts), the lowest position (for lift stands), or 90° to the wall (for full motion mounts), that means the system has been successfully reset.

Step 1: When the mount is powered on, press the small button on the control box with a thin tool as shown (take PLB-M0544 as an example). The unit emits a beep, indicating that the control box is on standby for program coding.

Step 2: Press the "" button on the remote control, and the control box repeatedly beeps for about 10 seconds indicating that the remote control is being programmed. The process will be finished automatically until you can’t hear a beep any longer.

Note: The TV Mount can be matched with up to 20 remote controllers. To clean up the data of all the remote controllers, press and hold the code matching button for 5 seconds then release. The unit will emit two beeps confirm the successful clean up and vice versa.

Every remote controller included in the package is exclusive for the corresponding LUMI product, which means any other brand’s remote controller cannot work with LUMI’s products. Because the remote controller is independent research and development product ONLY for LUMI with a 2.4Hz radio frequency.

If your remote controller is broken, please contact your place of purchase for a replacement.

1. 5G Wi-Fi Router (the most possible reason)

If the smart phone is connected with a 5G Wi-Fi Router, the receiving device of the product cannot receive connection request data from the phone.

2. Enterprise WPA

The Wi-Fi router uses Enterprise WPA which is not supported by the receiving device of the product.

3. UPNP (Universal Plug-n-Play)

Some routers disable UPNP, so that the device cannot be searched. (Some routers disable UPNP but do not disable the multicast address and port corresponding to UPNP, so this problem will not be caused.)

4. Port Restriction

Some routers set port restrictions, that is, only common ports such as port 80 are allowed to be used, which will result in failure to search for settings and control devices.

5. AP Isolation of Public Places

Wi-Fi hotspots in public places are often set with AP isolation, which isolates all clients connected to this hotspot and cannot access each other, resulting in no device search.

6. Router Connection Limit

Some routers have a connection limit, for example, only 16 clients can be connected at most, but more than 16 terminals are actually trying to connect, which will cause the clients to keep preempting the connection and the device cannot work properly (the device can find the network but can't surf the Internet).

7. Poor Network Environment

If the network environment is very poor, or the router is too far away and the signal is too weak, it will also cause the device to fail to be added. In this case, it may be successful after several attempts.

8. Different National Standard between Wi-Fi Device and Router

The Wi-Fi device and the router do not have the same national standard, and the inconsistency of the Wi-Fi channel may cause the connection to fail.

9. Other Possible Conditions

a). The router is set to static IP address assignment.

b). The router has set MAC address restrictions, and only the specified range of MAC addresses can be connected.

c). The router is set with an internet portal, that is, after connecting to the router, a web page will pop up automatically or manually, and the user needs to enter a password to access the Internet; if the user does not enter a confirmation for a period of time, the network connection will be disconnected.
