5.2 Status Indicators
The device is equipped with an LED indicator and a buzzer to provide feedback on its status. Specific indications (e.g., charging status, network activity, alerts) are defined by the Meshtastic firmware. Consult the Meshtastic documentation for a detailed explanation of these indicators.
5.3 Multifunctional Button
The single button on the device serves multiple purposes, depending on the Meshtastic firmware configuration. Common functions may include:
- Short press: Cycle through display modes, send a predefined message.
- Long press: Power on/off, enter pairing mode.
Refer to the Meshtastic app or documentation for the exact button functionalities implemented in your device's firmware version.
6. Maintenance
6.1 Cleaning
The SenseCAP T1000E has an IP65 rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. To clean the device:
- Wipe the device with a soft, damp cloth.
- Do not use harsh chemicals, solvents, or abrasive cleaners.
- Ensure the magnetic charging port is clean and dry before charging.
6.2 Battery Care
- Avoid exposing the device to extreme temperatures (below 0β or above 45β) during charging to prolong battery life.
- For long-term storage, charge the device to approximately 50% and store it in a cool, dry place.
7. Troubleshooting
7.1 Device Not Powering On
- Ensure the device is fully charged. Connect it to the magnetic charging cable and a power source.
- Perform a long press on the multifunctional button to attempt powering it on.
