Description
The AT422 has a built in feature of two "coins to start" settings, plus two "time per coin" settings. For example, a location could program the vacuum feature for $.75 for 4 minutes and another function for $2 for 4 minutes. If the end user would begin using the vacuum feature and later switch to the hot air dryer feature, the IDX AT422 would automatically recalculate the remaining time to the higher priced feature.
