3. Setup Instructions

Follow these steps to set up your Wireless HDMI Transmitter and Receiver system.

3.1 Receiver (RX) Connection

1. Connect the HDMI cable from the RX unit to an HDMI input port on your TV, monitor, or projector. Alternatively, use a VGA cable (not included) to connect the RX unit to a VGA input device.
2. Connect a USB-C power cable to the RX unit and plug the other end into a 5V/2A wall charger (not included). Ensure the RX unit is powered on.
3. Switch your display device (TV/monitor/projector) to the corresponding HDMI or VGA input channel. A blue screen should appear, indicating the RX is ready.
4. For first-time use, select the language by pressing the button on the back of the RX unit. Long-press the button for 2-5 seconds to confirm your selection. To change the language later, long-press for 10 seconds to restore default settings.

3.2 Transmitter (TX) Connection

1. Plug the HDMI Wireless Transmitter (TX) into the HDMI output port of your source device (e.g., laptop, camera, game console, set-top box). Use the provided Mini HDMI or Micro HDMI adapters if necessary.
2. Connect a USB-C power cable to the TX unit and plug the other end into a USB port on your source device or a 5V/1-2A wall adapter. The indicator light on the TX unit will illuminate.
3. Wait approximately 10 seconds for the TX and RX units to automatically synchronize. Once connected, your source device's display will be mirrored or extended to the connected display.

Note: Some HDMI output ports may not supply sufficient power to the transmitter. If the TX unit does not power on or the connection is unstable, ensure you are using the USB-C power cable connected to an external power source.

4.1 Basic Operation (Plug & Play)

The TIMBOOTECH Wireless HDMI system is designed for plug-and-play functionality.

4.3 Multiple Transmitters to One Receiver

The system supports connecting up to 8 Transmitters (TX units) to a single Receiver (RX unit). This feature is ideal for multi-presenter environments, allowing users to switch between different source devices with a single click on their respective TX units. This also provides privacy by allowing only one source to be displayed at a time.

4.4 Smartphone/Tablet Mirroring (Receiver Alone)

The Receiver (RX) unit can be used independently to stream video from your smartphone or tablet. When used alone, the RX unit supports 4K resolution. Other connection methods with transmitters support 1080P.

Connecting RX with your phone:

1. Ensure the external antenna is connected to the RX unit, and it is connected to your TV and powered via the USB cable.
2. On your phone, locate the Screen Mirroring function (e.g., 'Smart View' for Samsung devices). Select the RX unit (e.g., 'RX-BF...') as the target device.
3. For iOS devices: Go to your iPhone/iPad/Mac's Wi-Fi settings, find the Wi-Fi network named 'MiraScreen', and enter the password '12345678'. Launch a browser on your iPhone and access the IP address '192.168.203.1'. Click 'Internet', choose your router's account, and enter the password. Then, tap AirPlay Mirroring and select 'MiraScreen' as a target to auto-mirror.

6. Maintenance

To ensure the longevity and optimal performance of your TIMBOOTECH Wireless HDMI system, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the devices. Avoid using liquid cleaners or solvents, as they may damage the surface or internal components.
• Storage: When not in use for extended periods, store the devices in a cool, dry place away from direct sunlight and extreme temperatures.
• Handling: Handle the transmitter and receiver with care. Avoid dropping them or subjecting them to strong impacts.
• Ventilation: Ensure proper ventilation around both units during operation to prevent overheating. Do not cover the devices.

7. Troubleshooting

If you encounter issues with your TIMBOOTECH Wireless HDMI system, refer to the following common problems and solutions:

7.1 Connection Drops Constantly

• Power Supply: Ensure the Transmitter (TX) is receiving adequate power. If connecting to a laptop's USB port, try plugging the USB-C power cable into a dedicated 5V/1-2A wall adapter.
• Environment: Use the system in an open area with minimal obstructions. Walls, floors, and other physical barriers can interfere with the wireless signal.
• Distance: While rated for up to 165ft/50m, actual range can vary based on environmental factors. Try reducing the distance between the TX and RX units.
• Interference: Other wireless devices operating on 2.4GHz or 5.8GHz frequencies might cause interference. Try to minimize other wireless activity in the immediate vicinity.

7.2 Device Gets Hot During Use

It is normal for both the Transmitter (TX) and Receiver (RX) units to become warm during operation, especially during prolonged use or when transmitting 4K content. This is typically not an indication of a malfunction. However, ensure the devices have adequate ventilation and are not covered, which could lead to excessive heat buildup.

7.3 No Signal or Blue Screen on Display

• Power Check: Verify that both the TX and RX units are powered on and their indicator lights are active.
• Input Selection: Ensure your TV, monitor, or projector is set to the correct HDMI or VGA input channel where the RX unit is connected.
• Cable Connections: Check all HDMI, VGA, and USB-C power cables to ensure they are securely connected to both the devices and the power source/display.
• Source Device Output: Confirm that your source device (laptop, etc.) is configured to output video to the connected HDMI port.
• Reset: If a blue screen with instructions appears, try resetting the transmitter by unplugging and replugging it.
• Re-pairing: In rare cases, the TX and RX units might lose their pairing. While typically automatic, if issues persist, try restarting both units.
