(Paperless conference system, paperless office system) Conference control system generally uses wireless touch screen to realize several kinds of control of the venue equipment. In actual use, in many cases, the control fails due to the weak signal. Therefore, in the event of a fault, the power supply of the wireless device should be checked first, and if the battery voltage is too low, the transmitted signal is too weak, eventually leading to failure.

(Paperless conference system, paperless office system) Common fault analysis and maintenance methods for conference control systems are as follows:

Symptom 1: The master does not execute the command

Fault analysis: 1. The signal sent by the touch screen is not received; 2. The power management of the host is dead or not powered;
  Maintenance method:
  For wireless devices:
  (1) Check if the receiver receives the signal sent by the touch screen;
  (2) Check if the cable from the receiver to the main control unit is plugged in.
  For wired devices:
  (1) Check if the connection line of the touch screen to the main control unit is plugged in;
  (2) After turning off the system power for a few seconds, restart it;

Symptom 2: Some devices do not have infrared remote control

Fault analysis: 1. The infrared emitter of the device is not aligned with the infrared receiving port of the device; 2. The infrared receiving of the device is easily affected by the fluorescent tube (the remote controller of the device is not working at this time); 3. The device is Infrared data is artificially lost or modified;
  Maintenance method:
  1. Please check whether the paste position of the infrared emitter is moving; 2. Please turn off the interference source next to the device; 3. Re-infrared.

Symptom 3: Infrared learning is unsuccessful or successful but cannot be remotely controlled

Fault analysis: 1, may be a special infrared remote control code; 2, infrared remote control will be affected by the surrounding environment, especially by the influence of light reflection and the impact of infrared emitting objects.
  Maintenance method: 1, you can choose "special code" to try; 2, you can properly adjust the distance between the remote control and the learning window to try, if necessary, shading to prevent radiation and external infrared light source interference.

Symptom 4: Touch screen panel control is not working

Fault analysis: 1. If device selection occurs: the whole area control such as projector control and environmental control is not working properly, which may be the reason for the panel device being incorrect. 2. If there is an infrared remote control or device selection, etc.: If a function fails, it may be that a certain function module of the host is dead;
  Maintenance method: 1. Reset or contact the dealer; 2. Press the reset button on the front of the control panel or ask the professional company for repair.

Symptom 5: The touch screen suddenly turns black or restarts during operation

Fault analysis: The touch screen battery is too low;
  Repair method: Charge the touch screen immediately;

Symptom 6: Cannot turn the light on or off

Fault analysis: the module inside the relay does not pick up or disconnect;
  Maintenance method: 1. If the phenomenon occurs only occasionally, you can slightly tap the module in the relay to pull it in or off; 2. If it occurs frequently, notify the maintenance personnel to go to the site for inspection.

Symptom 7: Unable to adjust the brightness of the light

Failure analysis: program error or equipment damage;
  Maintenance method: contact the manufacturer for repair;

Symptom 8: Computer software cannot be controlled

Fault analysis: 1. The communication cable is disconnected or not connected. 2. The computer communication port is not set correctly.
  Maintenance method: 1. Check the communication cable for good condition; 2. Select the correct communication port and select other parameters in the data settings.
