5.2 Using the RScreen App (Mobile Device as Display)
The RScreen app allows you to use your iOS or Android phone/tablet as an additional display for the content being transmitted by the G70.
- Download the App: Search for "RScreen" on your device's app store (Apple App Store or Google Play Store) and install it.
- Connect to Transmitter's Wi-Fi: Plug the transmitter into your HDMI output device and power it. On your phone/tablet, go to Wi-Fi settings and connect to the network named "RScreen-xxxx" (where xxxx is a unique identifier). The default password is "12345678".
- Open RScreen App: Launch the RScreen app. It should automatically detect and connect to the transmitter, mirroring the content.
Within the RScreen app, you can access various settings:
- Display Mode: Choose between "Fluent" (prioritizes smoothness) or "HD" (prioritizes image quality).
- Receiver Manage: Specify devices and manage connections/disconnections.
- Channel Switching: If you experience dropouts, select a Wi-Fi channel with fewer access points and a stronger signal (indicated by a longer green bar) for optimal performance.
- Upgrade: Check for and install the latest firmware updates.

6. Troubleshooting
If you encounter issues with your TIMBOOTECH G70 Wireless HDMI system, please refer to the following common solutions:
- No Signal/Display:
- Ensure both the transmitter (TX) and receiver (RX) units are properly connected to their respective HDMI ports and are receiving power via USB-C.
- Verify that the display device is set to the correct HDMI input source.
- Check all cable connections for looseness or damage.
- Signal Drops or Buffering:
- The system has a range of 165 feet (50 meters) in open areas. Performance may be affected by solid walls or other obstructions. Try reducing the distance between the TX and RX units.
- Use the RScreen app's "Channel Switching" feature to select a Wi-Fi channel with less interference (look for channels with longer green bars).
- Ensure there are no other strong 5.8Ghz wireless devices operating nearby that could cause interference.
- App Not Connecting to Transmitter:
- Confirm your mobile device is connected to the "RScreen-xxxx" Wi-Fi network provided by the transmitter.
- Double-check the Wi-Fi password (default is "12345678").
- Restart the RScreen app and try connecting again.
- Audio Sync Issues:
- While the system is designed for low latency (0.1 seconds), minor audio sync variations can sometimes occur, especially with multiple receivers. Ensure all devices are within optimal range and consider adjusting display settings if available.
- New Receiver Not Pairing:
- Ensure the new receiver is powered on and connected to a display.
- Long-press the function button on the transmitter for 5 seconds to initiate re-pairing mode.
