1. Safety Information
November 2000 Page 7
W. Dittel GmbH
Section 1 Safety Information
Every radio, when transmitting, radiates energy into the atmosphere that may, under
certain conditions, cause the generation of sparks. All users of our radios should be
aware of the following warning:
Do not operate this radio in an explosive atmosphere (petroleum fuels,
solvents, dust, etc.)!
During normal use, the radio will subject you to radio frequency energy substantially
below the level where any kind of harm is reported.
TO ENSURE PERSONAL SAFETY, please observe the following simple rules:
• DO NOT transmit when the antenna is very close to, or touching, exposed parts of the
body, especially the face and eyes.
• DO NOT transmit on a busy channel.
• DO NOT press the transmit (PTT) key when not actually desiring to transmit.
• DO NOT transmit in closed aircraft or vehicles with the antenna (or part of it) inside the
cabin. This may cause malfunction of the avionics or trigger the airbag! Always operate
the radio FSG 90F(X) with a suitable outside / external antenna! Assure appropriate
lightning protection where elevated outdoor antennas are used.
• DO NOT operate the radio whilst driving. It should also be noticed that the use of a
hand held microphone while driving could constitute an offence under the Road Traffic
Regulations in certain countries.
• DO NOT allow children to play with any radio equipment containing a transmitter.
• DO NOT call radio’s SET-UP in flight or whilst driving a vehicle. Transmit and receive
are partially disabled!
• After each SET-UP check all settings of the radio and cockpit instruments for correct
function before the next flight or application!
• Always switch OFF the radio first when installing the unit into vehicles or aircraft when
removing from it!
• Always switch OFF the radio first when starting an engine or vehicle!
• When operating the FSG 90F(X) on a 24 Vdc source a suitable Voltage Converter
24 Vdc/12 Vdc of at least 4 Amps must be used!
• The FSG 90F(X) may be used exclusively for communication on the airband
frequencies.
• Unauthorized modifications and changes of the system are forbidden.
• When replacing defective parts use only original spare parts or standard parts
recommended by the manufacturer!
• In aircraft or vehicles a suitable noise canceling microphone or headset for aircraft
radios shall be used.
• A backup microphone should always be carried during any flight. Even new
microphones can fail.
• Volume is very important. Increasing speaking levels while the lips are facing the
microphone, but not straining or pushing to yelling levels will increase clarity.
FSG 90F System
1. Safety Information
Page 8 November 2000
W. Dittel GmbH
• Prior to any flight verify proper FSG 90F(X) functions by means of a short
communications test. It has to be taken into account that with a faulty antenna or
cable this COM test may absolutely turn out positive at the airfield or in short distance
to the ground station. But at distances of 2 to 6 miles a faulty antenna and/or cable
will cause communication breakdown!
• Push-to-Talk keys may stick occasionally. Therefore, observe while transmitting the
transmit (TX) symbol at the FSG 90F(X) display. This TX symbol must disappear
when releasing the PTT key. After 2 minutes continuous TX the built-in transmit time
out timer disables the transmitter in order to avoid continuous channel blocking.
Then, the whole display warns by continuous flashing. Refer to appropriate hints in
this manual.
• Replace blown fuse only against correct type with specified nominal value.
Investigate the cause.
1.1 Used Symbols
In this manual the following symbols are used:
DANGER!
describes an immediate threatening danger! Failing to observe the note
may cause death or heavy injuries!
CAUTION!
describes a special note for operation. Failing to observe the note may
cause damage of the transceiver and/or stored data may be deleted (SETUP or user programmed memory)!
IMPORTANT!
describes explanations and other useful hints. Failing to observe the note
may cause degraded performance and/or unsatisfying operation!

2. General Description
November 2000 Page 9
W. Dittel GmbH
Section 2 General Description
2.1 Introduction
This installation and operating manual IM 034.00 contains instructions and descriptions
for application, installation, presetting operation and testing, as well as interconnecting
diagrams of the multi-use FSG 90F / FSG 90F-H1 VHF/AM Transceiver System of Walter
Dittel GmbH, Luftfahrtgeraetebau, D-86899 Landsberg, Germany.
The maintenance manual MRM 034.00 contains detailed circuit description, repair
instructions, alignment procedures, testing instructions, and an illustrated parts list.
2.2 Models of the FSG 90F System
This manual refers to 2 out of 8 models available up to now.
F10194, VHF/AM Dual Mode Airband Transceiver FSG 90F
Frequency range: 118.000 to 136.975 MHz, channel spacing 8.33 kHz/25 kHz, results in
2,278 channels, or 118.000 to 136.975 MHz, channel spacing 25 kHz, results in 760
channels. 99 channel memories for combined 8.33/25 kHz mode, additional 99 memory
channels for '25 kHz only' mode, 6 Watt RF output power, 10 - 16.5 Vdc supply. The
radio fits a standard ARINC NORM rectangular opening.
IDENT.: MODEL 90F-25/8.33 (ED-23B CLASS C / CLASS E RECEIVER, CLASS 4 / CLASS 6
TRANSMITTER).
F10306, VHF/AM Dual Mode Mode Airband Transceiver FSG 90F-H1
Frequency range: 118.000 to 136.975 MHz, channel spacing 8.33 kHz/25 kHz, results in
2,278 channels, or 118.000 to 136.975 MHz, channel spacing 25 kHz, results in 760
channels. 99 channel memories for combined 8.33/25 kHz mode, additional 99 memory
channels for '25 kHz only' mode, 10 Watt RF output power, 10 - 16.5 Vdc supply. The
radio fits a standard ARINC NORM rectangular opening.
IDENT.: MODEL 90F-H1-25/8.33 (ED-23B CLASS C / CLASS E RECEIVER, CLASS 4 / CLASS 6
TRANSMITTER).
2.3 Application
The equipment is well suited for operation in powered aircraft and helicopter with
reciprocating turboprop and turbojet engine.
Ultra low power consumption in conjunction with extremely wide DC supply voltage
range, small dimensions and wide scope of accessories allow universal FSG 90F(X)
airborne applications in any powered aircraft, motor glider and Ultralight, and in glider
and balloon, for primary or (also battery supplied) backup operation.
