• Keyboard: Used for text input and command execution.
• Trackball: Navigate through menus and select options. The trackball has directional inputs (UP, DOWN, LEFT, RIGHT) and a central 'Boot' button (I000).

Common menu options visible on the screen include "Scour", "Dis", "GPS", "KB" (Keyboard), "SETT" (Settings), "Rx" (Receive), "Message", "TX" (Transmit), and "Radio Configure".

2. LoRaWAN Communication

The integrated SX1262 LoRa module supports various frequencies. Ensure your device is configured for the correct frequency band for your region (433MHz, 868MHz, or 915MHz). The transmit power is +22dBm.

Use the "Radio Configure" option in the menu to set up LoRa parameters.

3. GPS Functionality

The T-Deck Plus includes a GPS module. Access GPS-related functions through the "GPS" menu option. Ensure the device has a clear view of the sky for optimal satellite reception.

4. TF Card Usage

Insert a TF (microSD) card into the designated slot for data storage, logging, or custom firmware. Ensure the card is formatted correctly (e.g., FAT32) before use.

5. Audio Features

The module is equipped with a microphone and speaker, enabling audio input and output. These can be utilized for various applications, such as voice communication or sound recording, depending on the loaded firmware.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Avoid using liquids or abrasive cleaners.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: For long-term storage, charge the battery to approximately 50% to prolong its lifespan. Avoid fully discharging the battery for extended periods.
• Firmware Updates: Regularly check for firmware updates from the manufacturer to ensure optimal performance and access to new features.

Troubleshooting

Device does not power on:

• Ensure the battery is charged. Connect the device to a power source using a USB-C cable.
• Verify the power switch is in the ON position.

LoRa communication issues:

• Check if the LoRa antenna is securely attached (for external antenna versions).
• Confirm that the LoRa frequency is correctly configured for your region.
• Ensure both transmitting and receiving devices are within range and on the same frequency.

GPS signal not acquired:

• Move the device to an open area with a clear view of the sky.
• Allow sufficient time for the GPS module to acquire satellite signals (first fix can take longer).

LCD display not working:

• Restart the device.
• Ensure the device is powered on and the battery is not critically low.
