Count-up timer (stopwatch function)
If you assign a switch and start the stopwatch with the
initial value of “0:00”, the timer runs up until the maxi-
mum of 180 minutes and 59 seconds, then re-starts at
0:00.
Count-down timer (alarm timer function)
You can select a starting time within the range 0 to 180
minutes in the left-hand minutes field, and a starting
time within the range 0 to 59 seconds in the right-hand
seconds field. Any combination of times can also be
selected.

When you operate the assigned switch, the stopwatch
now starts from the set initial value,
counting down
(“Timer function”). When the set time has elapsed, the
timer does not stop, but continues to run so that you can
read off the time elapsed after reaching zero. To make
this clear, the over-run time is shown highlighted (black
background).

The “alarm timer” is reset by simultaneously touching
the  or  buttons of the right-hand touch-key
(

), once you have halted the timer.
Note:
A count-down timer is indicated in the basic display by
a flashing colon (:) between the minutes field and the
seconds field.
Phase 2, Phase 3 and Phase 4
You will automatically be in the “normal” flight phase 1
unless you have already assigned a switch to phases 2,
3 or 4.
Both the number and name of this flight phase are fixed
permanently as “normal”, and cannot be changed. For
this reason the “normal” phase is simply concealed, i. e.
it is not displayed as phase 1.

It is also important to understand that the flight phases
have their own inherent priorities which need to be ob-
served, particularly when assigning individual switches.
The underlying scheme can be described as follows:
If all assigned flight phase switches are closed or •
open, the “normal” flight phase is active.
If only one switch is closed, then the flight phase as-
•
signed to the currently closed switch is active.
If two switches are closed, then the flight phase with
•
the lower number is active.
For example, this would be phase 2, if one of the
