From the 7CAP manual:
Adjustability:
• Count down timer: starts from the chosen time, displays time remaining. If the time is exceeded, it continues to count
below 0.
• Count up timer: starts at 0 and displays the elapsed time up to 99 minutes 59 seconds.
• Independent to each model, and automatically updates with model change.
• In either TIMER mode, the timer beeps once each minute. During the last twenty seconds, there's a beep each two seconds.
During the last ten seconds, there's a beep each second. A long tone is emitted when the time selected is reached.
• To Reset, choose the desired timer with the SELECT key (while at the startup screen), then press and hold DIAL for 1 second.
• Activation by either direction of SWITCH A-H, bySTICK (1-4) . THROTTLE STICK is convenient if you are keeping track of fuel.
• To quickly reset any timer from the home screen, cursor down until the timer blinks. Press dial to reset.
