Why is the keypad swelling on my horiba LAQUA?

If you notice swelling of the keypad on your Horiba Measuring Instruments, it might be due to using the instrument at high elevation or another location where the air pressure differs from sea level. To address this, briefly open and then close the serial cable cover to equalize the pressure. Ensure the cover is correctly closed afterward to maintain dust and water proofing.
