You might be looking at the wrong manual. The shield icon next to the red LED is on the 15T WP (WaterProof) version. The WP version has no calibration button.
Here is the manual for the 15T WP:

The manual has absolutely no instructions for calibration! However, the 12T WP manual does, so you might try that:
