CoMo AV Instruction Manual
Your CoMo is one of the most versatile, well featured and easy
to operate flight instrument systems.
To provide you with the most straightforward access, the manual
is divided into 8 chapters.
For rapid access the first chapter gives the important instructions:
keys, functions, settings, displays and menus.
A more detailed description of the individual instructions and
functions is given from chapter 2 on. Chapter 3 outlines the
software status.
The table of contents is found on page 9.

Explanation of
symbols:
1 CoMo AV Rapid Access
1.1 The CoMo AV Keyboard
Adjustment Group
Adjustments can be
performed by the keys
in this section. They will
be mainly used before
take-off or after
landing.
Rotary-Button
Push the Button to shift into next Flight
profile (if active). Rotation turns pages
forward or backward.
A long push on the button opens the menu
of the instrument. Rotation selects a
function, which is confirmed by a brief
push. Within the menu any adjustment can
be executed. The page-display will provide
additional information.
For easy operation the Keys (Push-
Buttons) are arranged in two groups:
The Function Group is on the right hand
side of the instrument and the
Adjustment Group is along the bottom.
The on|off-Button
in contrast to most other flight instruments
the CoMo is equipped with a real on|off-
Button. A short push will turn the CoMo on. A
long push will turn it off again.
In adjustment mode this button assumes the
"exit" function. False inputs may be reset by a
short push. Push repeatedly to leave the menu.

Logger-Function-Button
This button allows flight data to be recorded. A long push
will start/stop the recording.
In the standard version your personal logbook is activated
(date, max/min values), and in the OLC version the "OLC-
Logger" is activated. (A change of more than 15 m in altitude
will automatically start the recording).
Functional Group
The keys in this section offer direct
access in flight.
All Function buttons are located next to
the corresponding display, making
incorrect operation most unlikely.
Altitude-Function-Button
A brief push shifts to the next value
(e.g. from "alt 1" to "alt 2").
Make a long push to enter the
adjustment menu.
Page-Function-Button
Switches between all page
displays.
A long push opens the
corresponding menu.
Speed-Function-Button
Switches between different speed-
indications, according to connected sensors.
Track-Function-Button
(no function yet)
Acoustic-Function-Button
Acoustic can be set to "off", "soft" or
"loud".
A long push opens the acoustic menu for
further adjustment.
CLR-Button
In adjustment mode the Acoustic-Function-
Button converts into a Clear-Button, by
which a value can be set to "0" directly (e.g.
altitude of landing ground).

Bat. full Bat. empty
Analog-Vario-Display
(direct-vario)
The position of the needle is quickly
and precisely discernible. Shows
immediate climb- or descend-rate up
to 10 m/sec (current value shown on
display: 1,7 m/sec climb-rate)
GPS-State-Indication
This indication flashes
when the instrument is
seeking satellites. When
ever a satellite is found,
one more dot will light
up. All dots on means
that the GPS receives 6-
12 satellites.
Battery-State-Indication
The number of dots indicates the
remaining battery life (more
details on battery-life are found
on the Page-Indication "page 2")
Audio-Indication
Shows if the acoustic
function is set to "soft",
"loud" or "off".
OLC-Logger-Indication
shows if the instrument
is recording flight data
(only with built-in OLC
logger) Page-Display
in adjustment mode:
hints for operation
Profile-State-Indication
Shows which profile is activated
(one dot = profile 1).
1.2 The CoMo AV Displays
Piezo Beeper
for audio variometer.

Track-Display
Gives information about
the track (only in com-
bination with a GPS,
otherwise temperature
is displayed).
Altitude-Display
3 individually adjustable
altitude-indications are
available.
Speed-Display
In combination with a GPS the SOG
(Speed Over Ground) can be shown
– enhancing your safety.
Page-Display
Displays further information
like time, date, battery-state
(up to nine pages according to
software).
In adjustment-mode the page-
indication turns into a built-in
instruction-manual.
Digital-Vario-Display
(integrated-vario)
This gives the averaged rate of
climb (the timespan for the average
can be adjusted in the menu).

Track and the north-pointer
are only shown when the
instrument moves faster
than 1,5 km/h (the GPS is

without movement!).

1.4 on|off Switching, Operation Schema
The operation of the CoMo is very simple.
Generally there are 3 actions:
The following schema, explains all operation and setting
modes.
We differentiate between "fast" and "main menu” settings.
This is explained in more detail in section 2.1.1. for altitude
adjustment.
Switch on: Push the red on/off-Button
Note: if a GPS Module is connected, there are two options:
- a brief Push on the Rotary-Button will switch the GPS on
- a brief Push on the CLR-Button will leave the GPS off
- a brief Push on a Function-Button will choose the next
function of the corresponding display, e.g. from "alt 1" to "alt 2".
- a brief Push on the Rotary-Button will shift flightprofiles.
- Rotating the Rotary-Button will turn the page display
forward or backward.
- a long Push on any Button will switch to the adjustment
mode of a displayed function.
(Fast Setting)
- a long Push on the Rotary-Button will switch to the
adjustment menu.
(Main menu Setting)
Within the Main Menu:
- turning the Rotary-Button chooses a function or
adjusts values (selection is also possible by briefly pushing
the Page Button).
- a brief Push on the Rotary- or Page-Button will confirm
the selection of the value (display ‘OK’ confirms storage)
(Main Menu Setting).
-a brief Push on the related Function-Button confirms the value
(display ‘OK’), and the menu is departed (Fast Setting).
- a brief Push on the Exit-Button shifts one level back within
the menu. Changed values will not be retained.
Push the Exit-Button repeatedly to leave the main menu.
Switch off: A long Push on the red on/off-Button
Auto-Power-Off Function: If there is less than 15 m change in
altitude within 15 min and SOG (only with activ GPS) is less than
4.4 km/h, your CoMo will turn off automatically.
