I cannot use the Android TV dongle's remote control to control Android TV system or my projector? How can I fix it?

● QS01 Android TV dongle

Please update the Android TV system to fix the issue.

If the issue remains, please follow the steps below to do troubleshooting:

1. Power cycle the projector and wait for 5 mins then check if the issue is
    still up.

2. Check if the Android TV dongle (QS01) is installed in the specific HDMI
    port. If not, please fit in the dongle and check again.

3. Check if “BenQ HDMI Media Streaming (QS01)” is “ON” in the OSD
    menu. If not, please turn it ON and power cycle the projector.

4. Check if you can call out the “OSD menu” with “Menu” key of the projector
    keypad. If you can’t, please contact BenQ for further assistance.

5. Check if you can see “All Projector Settings” on the home screen. If you
    can’t, please contact BenQ for further assistance.

6. Press and hold “OK” to pair the remote control.

● If the remote control flashes RED lighting: Please long press the “OK” button
    on the remote control to pair it with the Android TV dongle when the pairing
    page pops up.

● If the remote control flashes BLUE lighting: Please check whether the status
    is “Connected” or not (check the status under “Android TV setting > Remote
    & Accessories”). If not, please unpair the remote control, and pair the
    remote control with the Android TV dongle again. You may refer to this
    video for more details about remote control pairing:

7. Check if the “Prime Video” button on the remote control is working or not. If
    not, please contact BenQ for further assistance.

8. Check the “Source” button on the remote control work or not. If not, please
    contact BenQ for further assistance.

2. If your remote is not connected to the BenQ QS02, please restart your
    projector to enter the Bluetooth pairing process, and go to Step 3 if your
    remote successfully connects to the BenQ QS02 after rebooting.

3. Press and hold the Play/Pause button on your remote if your remote is
    connected to the BenQ QS02.

4. Then, press the Navigation and OK buttons to go to Settings > Device
    Preference > Display & Sound > HDMI CEC  > CEC, and turn on CEC if it
    isn't enabled already. Restart your projector to complete the process.

5. If the problem persists after the above steps, please disconnect other
    devices connected to the projector and keep only the QS02.
