3)Set service menu item 22 to either OFF [“Ch” goes off after 10 minutes] or ON [“Ch” keeps flashing] (factory default: OFF). Even if set to ON, “Ch” goes off when the “ON/OFF” button on the operation panel is switched off.

4)Set service menu item 23 to ON to stop the beep when the “ON/OFF” button is switched off but to resume flashing “Ch” when the “ON/OFF” button is switched back on unless the wash tank is refilled (factory default: OFF). Press the power switch (GFCI) or turn off the external power supply to stop both the beep and “Ch” indication.

Set service menu item 23 to OFF to stop both the beep and “Ch” indication once the “ON/ OFF” button is switched off.

If service menu item 23 is set to ON, “Ch” keeps flashing even if service menu item 22 is set to OFF.
