Battery Location: On the circuit board inside the TPC product

Battery Specification: CR2032 3V Lithium Battery

Battery Removal: Remove the securing adhesive above the battery, gently pull the positive terminal clip, and the battery will pop out automatically.

Battery Installation: First place the battery into the positive terminal clip, then gently press the other end down until it fits under the plastic clip. Verify that the battery is properly seated in both plastic clips and the metal positive terminal clip.

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 triple protection film to the TPC can effectively prevent contamination and corrosion caused by dust, oil stains, and other substances generated during production. Therefore, if necessary, the TPC can be protected with a triple protection film. This section takes the 1271Gn model as an example; the film application steps for other TPC models are similar.

l Preparation Tools: Matched triple protection film for TPC (available through the TPC's purchase channel), dust-free cloth, anti-static environmentally 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 Precautions:

1）Before applying the Triple Protection Film, the factory-installed PET protective film must be peeled off.

2）The Triple Protection Film is a consumable. If edge lifting or bubbling is detected, it should be replaced with a new one.

3）When replacing the Triple Protection Film, peel it up from the bottom right corner of the front panel. Be

careful not to scratch the sealed film.
