dispense at any time, select Change Anytime. If you would like your unit to only dispense change
after a wash package is purchased, select Change After Purchase Only. Note that Change Anytime
option does not return the bill from the validator but rather dispenses change from the coin and bill
dispensers.

is 5 minutes. To be able to toggle the alarm on and off, enter an alarm code. The code can be up to
8 digits long. Once the alarm is enabled, a bell icon will be displayed in the upper left corner of the
sales screen. If you open the right (vault) side door of the unit without logging into Maintenance
Mode, the alarm will chirp, then sound after one minute. Logging into Maintenance mode will
silence the alarm. Once the doors to the unit have been closed and locked for one minute, the alarm
will reactivate.
NOTE: Please ensure that the alarm code does not interfere with any existing POS or house account
codes. Codes starting with the digits 44 will not be allowed.
