18. ADJUSTMENT
When the time-axis synchronization (POC) is programmed to "on", the gaps between the pens may change over
time, resulting in error between their time-axis. This adjustment is for correction of these changes. It is
recommended to adjust them once a year for maintaining the time-axis synchronization.
