1.5.1  Replacement battery

Battery location: On the circuit board inside the TPC product.

Battery specifications: CR2032 3V lithium battery

Disassemble the battery: Remove the adhesive tape securing the battery; gently push the positive terminal to disengage the battery, and the battery will automatically pop out.

Install the battery: First, insert the battery into the positive terminal clip; then, gently press the other end against the plastic clip. Check whether both plastic clips and the metal positive terminal clip are securely in place.

During installation, please take care to avoid a short circuit between the positive and negative terminals of the battery.

1.5.2  Touch calibration

Enter TPC In the system settings interface, press and hold on a blank area. 3 The touch calibration process will begin in seconds.

TPC Calibration: Use a stylus or finger to lightly press and hold the center point of the crosshair cursor. When the cursor moves to the next point, lift it. Repeat this action until the message "New calibration settings have been measured" appears. Click the "Confirm Calibration" button to save and exit the calibration program.

Place your finger lightly and accurately on the center of the crosshair cursor and hold it for at least one second as the target moves across the screen. Repeat this action.

1.5.3  Three-proof film

Applying a moisture-proof, dust-proof, and corrosion-resistant film to the TPC can effectively prevent erosion caused by dust, oil contamination, and other contaminants generated during production; therefore, if necessary, this protective film can be used to safeguard the TPC. This article uses the 1271Gn model as an example for explanation; the film application process for other TPC models is similar.

l Required tools: TPC compatible IP-rated protective film (available through screen suppliers), dust-proof cloth, anti-static eco-friendly cleaner, and roller.

l operating steps ：

1) Clean the screen. Use a dust cloth to wipe away dirt from the front panel to prevent bubbles when applying the screen protector. If the TPC surface is heavily contaminated, use a cleaning agent to help clean contaminants in the crevices around the edges.

2) Remove the factory-installed PET protective film and clean any residue to prevent bubbles from forming during application.

3) Peel off a corner of the backing film on the right side. Align the right side of the film with the right side of the TPC. With your left hand, slowly peel off the backing film, and with your right hand, apply even pressure to gently push the film onto the screen from right to left

4) After applying the film, use a roller to press the adhesive backing firmly to prevent air bubbles.

l matters need attention ：

1）Before applying the IP67/3A protection film, you must remove the factory-provided PET protective film.

2）The three-proof film is a consumable; if you notice the edges are lifting or bulging, you will need to reapply a new film.

3）When replacing the waterproof film, lift the waterproof film from the lower right corner of the front panel; be careful not to scratch the sealing adhesive film.
