In setup mode the volume can be adjusted by holding the magnet adjacent to the ashing setup
LED and removing it at the desired volume level. If min or max volume is reached, the con rmation
LED stops ashing. To alter the direction of adjustment, remove the magnet for one second and re-
apply. Saving the volume setting is performed at the control panel.
Please check with panel manufacturer for compatibility of the above setup/test modes.
