Program description:

Timers

Switching between “count-up” and “count-down”

Stopwatch mode (count-up timer)

If you assign a switch to any of the timers, and then
program it to start running at the initial value “0:00”,
it will count “up” until max. 999 min. and 59 sec., at
which point it will start again at 0:00.

“Timer” (count-down timer)

Use the left-hand

SEL

fi eld in the “Timer” column to

set a start time within the range 0 to 180 minutes, and
use the right-hand

SEL

fi eld to set a start time bet-

ween 0 and 59 seconds.

(Pressing

CLEAR

= “0” or “00”.)

Procedure:

1. Select the

SEL

fi eld using the rotary control,

2. Brief press on the rotary control,

3. Set the pre-set time in the highlighted min. / sec.

fi eld using the rotary control (not pressed in),

4. A brief press on the rotary control concludes the

process.

When the assigned switch is operated, the timer
starts from this pre-set initial value and counts back-
wards (“timer function”). If necessary, pressing

CLEAR

in the basic display resets the timer to the

starting time. When the pre-set time has elapsed,
the timer does not stop; instead it continues running
so that you can read off the over-run, i. e. the time
elapsed after zero.

Count-down timers

are identifi ed in the basic display

by a fl ashing colon (:) between the minutes and the
seconds fi elds.

“Alarm” timer

In the “Alarm” column you can defi ne a time within the
range 5 to 90 seconds in 5-second increments. At the
set time before zero you will hear an audible signal,
eliminating the need for the pilot constantly to check
the screen.

(Pressing

CLEAR

= 0 s.)

Audible signal sequence:

90 sec. before zero: every 10 seconds

30 sec. before zero: triple tone

20 sec. before zero: double tone

10 sec. before zero: every second

5 sec. before zero: every second, at higher fre-

Press

with the timer stopped to reset the “Ti-

mer”.

Notes:
• An example of “Operating the timer via the C1

stick” can be found on page 170.

• If you alter the function of a timer, the new mode

only becomes active when you stop the timer and
reset it by pressing

CLEAR

• If you have set up multiple flight phases, the ap-

propriate flight phase name appears on the screen
in place of the GRAUPNER/JR logo.

• A “Flight phase timer” assigned to a flight pha-

se in the »

Phase settings

« menu appears in the

vacant line above the GRAUPNER/JR logo. For
more details of this please read the section on the
follow ing pages describing the »

Flight phase ti-

mers

« menu.

Resetting

stopped

timers

Provided that you have already

stopped

the timers,

pressing the

CLEAR

button in the basic display re-

sets them to their starting value.

Note:
If the “Auto timer reset” function in the »

Base setup

model

« is set to “yes”, then all timers (except the mo-

del time and battery time) are automatically reset to
the appropriate starting value when the transmitter is
switched on.

Typical application:
The “stop watch” and “flight timer” are both to be star-
ted simultaneously using the C1 stick as soon as the
user-defined switching point is exceeded.

In the »

Control switches

« menu (see page 94) the

two control switches “G1” and “G2” are already pre-
configured, with switching points at -75% for “G1” and
+75% for “G2”. Simply move the C1 stick to the positi-
on at which the timers are to be switched off.

“Top: stop watch” and “Centre: fl ight timer”.

Activate the switch assignment point in the “Upper”
line, then move the C1 stick beyond the switching
point in the direction of switch “on”. On the right of
the screen you will now see “G1” or “G2”, depending
on the direction of the movement. Move the C1 stick
back to the starting point, and repeat the assignment
in the “Centre” line:

The stopwatch will now stop when the stick is below
the switching point, and resume running above the
switching point. In contrast, the flight timer, which also
started running when the set switching point was ex-
ceeded, can only be stopped by pressing the

ESC

button. It can then be reset to the starting value by
pressing

CLEAR
