There are four different types of timers: fix set time, interval, countdown and stopwatch.
Fix set time
A timer of the type fix set time expires periodically at the specified time at the specified days.
A timer of the type interval expires periodically after the specified interval and starts over again then. It will first be started with its configuration and with each restart of the icom Data Suite.
A timer of the type countdown will be started within an action and expires after the specified interval. It can also be paused or stopped before its expiry within an action. A paused timer continues with the count when it has been paused after a new start; a stopped timer starts again with the initial value. This type of timer allows to realise sophisticated applications like cascading alarm messages or a time-delayed start of actions like a profile change.
A timer of the type Stopwatch will be started, paused and stopped within an action. A paused timer continues with the count when it has been paused after a new start; a stopped timer starts again with zero. The timer will be reset with a restart of the device or icom Data Suite.
