3. What's in the Box
Upon unpacking, please verify that all the following items are included:
- FOTRIC TD2 Acoustic Imager Body
- Rechargeable Lithium Ion Battery (pre-installed or separate)
- Data Cable (USB-C)
- Power Supply Adapter
- MicroSD Card (pre-installed or separate)
4. Setup
4.1. Charging the Battery
- Connect the data cable to the TD2 Imager's charging port.
- Connect the other end of the data cable to the power supply adapter.
- Plug the power supply adapter into a standard electrical outlet.
- The charging indicator on the device will illuminate. Allow the device to charge completely before first use.
4.2. Inserting the MicroSD Card
If the MicroSD card is not pre-installed, locate the MicroSD card slot (usually on the side or bottom of the device). Gently insert the MicroSD card with the contacts facing down until it clicks into place. Ensure it is inserted correctly to avoid damage.
5. Operation
5.1. Powering On/Off
- Power On: Press and hold the power button (typically marked with a power symbol) until the screen illuminates.
- Power Off: Press and hold the power button until a shutdown prompt appears on the screen. Select "Power Off" or similar option.
5.2. Navigating the User Interface
The TD2 features a 3.5-inch touchscreen for intuitive navigation. Tap icons to select functions, swipe to scroll, and use pinch-to-zoom gestures where applicable. The main screen typically displays the real-time acoustic image overlay, frequency range, sound pressure level (dB), and battery status.
5.3. Leak Detection and Sound Source Localization
The primary function of the TD2 is to visualize sound sources. As you scan an area, the device will display a color overlay on the visual image, indicating the intensity and location of sound emissions. Higher intensity colors (e.g., red, yellow) typically denote stronger sound sources or leaks.

5.4. Acoustic Image Focus
The TD2 features an acoustic image focus function that allows you to concentrate the sound detection on a specific area, reducing interference from ambient noise. This is particularly useful for pinpointing small leaks or anomalies in noisy environments.

5.5. Display Modes
The TD2 offers several display modes to suit different inspection needs:
- Single-Source Mode: Focuses on the strongest sound source detected.
- Multi-Source Mode: Displays multiple significant sound sources simultaneously.
- Hologram Mode: Provides a more comprehensive acoustic visualization, often used for complex sound environments.

5.6. Recording and Saving Data
The TD2 allows you to capture images and potentially video recordings of your inspections. Refer to the on-screen menu for options to save data to the MicroSD card. Saved data can be transferred to a computer via the data cable for further analysis.
6. Maintenance
6.1. Cleaning the Device
Wipe the device body and screen with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the microphone array or charging ports.
6.2. Battery Care
To prolong battery life, avoid fully discharging the battery frequently. Store the device in a cool, dry place when not in use for extended periods, with the battery charged to approximately 50%.
6.3. Storage
Store the TD2 in its protective case to prevent damage from impacts or environmental factors. Avoid extreme temperatures and high humidity.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery. | Charge the device using the provided power supply. |
| No acoustic image displayed. | Microphone array obstructed; frequency range too narrow; no significant sound source. | Ensure microphone array is clear. Adjust frequency range settings. Move closer to potential sound sources. |
| Screen is unresponsive. | Software glitch; extreme temperature exposure. | Perform a soft reset (refer to device settings or hold power button for extended period). Allow device to return to normal operating temperature. |
| Cannot save images/videos. | MicroSD card full or improperly inserted; card error. | Check MicroSD card capacity and insertion. Reformat the card (this will erase data) or try a different card. |
