The random interval setting (RAN) on the silver model replaces the average interval setting (AVE) on the previous (dark grey) model. The RAN setting is available in combination with all other advanced functions. For example, the MotivAider can be programmed to send signals on a random interval basis with the seconds (SEC) input units setting also selected.
When you move the SET/RUN switch to RUN, the MotivAider will send the first signal at the set interval and all subsequent signals at randomly selected intervals up to (and including) the set interval. It will continue sending signals at randomly selected intervals until the SET/RUN switch is placed at SET.
To illustrate, if you set a time interval of 10 minutes, the MotivAider will send the first signal in 10 minutes followed by signals at randomly selected intervals between 1 minute and 10 minutes.
If you set a time interval in minutes, the MotivAider randomly selects from whole minute intervals, for example, 1 minute, 4 minutes, 9 minutes, etc. If you set an interval in seconds, the MotivAider randomly selects from intervals in seconds.
By the way, with input units set to seconds (SEC), you can enter any interval ranging from 10 seconds to 4999 seconds. With input units set to hours/minutes (HM), you can enter any interval from 1 minute to 11 hours and 59 minutes.
