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 radio near flammable liquids or nearby explosive devices.

During normal use, the radio will subject you to radio 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 inside vehicles or aircraft with the whip antenna, always operate the radio
with a suitable external antenna!

• DO NOT hold the transmit (PTT) key in when not actually desiring to transmit.

• DO NOT allow children to play with any radio equipment containing a transmitter.

• 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 offense under the Road Traffic Regulations.

• In order to prevent corrosion, the radio should be rinsed with tap-water after use in sea-water.
Wipe dry using a clean, lint-free cloth.

Nickel-metal hydride Batteries Handling Precaution

• Never dispose of Ni-MH batteries in a fire or expose to high temperatures.

• Do not connect the positive (+) and negative (-) terminals of Ni-MH batteries together with

electrically conductive material, including lead wires.

• Do not transport or store Ni-MH batteries with their uncovered terminals.

• Do not strike or drop Ni-MH batteries. Sharp impacts or concussion to batteries may result in

leakage, heat generation and bursting.

• Never disassemble, modify or reconstruct Ni-MH battery packs.

• Ni-MH batteries contain a strong colorless alkali liquid. The alkali is extremely corrosive and

will cause skin damage. If any liquid from a Ni-MH battery comes in contact with a user's eyes,
they should immediately flush their eyes with clean water enough and consult a doctor. The
strong alkali can damage eyes and lead to permanent loss of eyesight.

Ni-MH

This radio contains a Ni-MH battery!
DO NOT dispose worn out Ni-MH batteries with domestic waste. Consumers are

obliged by law to return Ni-MH batteries at the end of their service lives to the
public collecting points set up for this purpose or point of sale.

Section 1

General Description

1.1 Introduction

This Operation Manual, 029.HB.04E, contains instructions and descriptions for
application and operation of the Dittel’s FSG 5W hand-held VHF AM transceiver
with 1,040 operating channels.

The Maintenance/Overhaul Manual 029.HB.HB.12 contains a detailed circuit de­scription, repair instructions, alignment procedure, testing instructions, and a de­tailed Illustrated Parts List.

1.2 Equipment Description

The basic model FSG 5W is the heavy-duty water- and dustproof version of the
proven self-contained portable hand-held AM transceiver FSG 5 with extended fre­quency range. It operates throughout the VHF band 118.000 to 143.975 MHz with
25 kHz channel spacing, thus providing 1,040 communication channels in every
single unit, being down compatible to ICAO Annex 10. The channel selection is
done by turning two knobs (MHz- and kHz-knob) and by reading the frequency dis­play (5 digit liquid crystal display), which are conveniently located on the front
cover.

A one-Watt transmitter (approx. 3.6 Watt PEP) and a highly sensitive and selective
receiver make long-range communication links possible, depending on the location
and antenna in use.

The ultra low current consumption (e.g. 17 mA drain in standby) makes 15 to 24 hrs
of operation with 10% to 5% in transmit mode from one standard battery charge a
reality. The solid aluminum case is dust- and waterproof, enabling the transceiver of
being used even under rough environmental conditions (-20°C … +60°C/

-4°F…+140°F).

Well-selected accessories are available for body-worn, hand-held, portable, mobile
and ground station operation even in noisy environment. If desired, dynamic stan­dard or dedicated microphones, headsets, helmet sets, voice operated PTTs and
battery chargers can be connected by means of a waterproof general-purpose con­nector on top of the case.

Internal circuits used in the FSG 5W are a combination of high quality components,
sophisticated design and new electronics technology.

The design of this tiny package was enabled by a high degree of circuit integration
(21 integrated circuits versus 14 transistors). Electrically, the FSG 5W consists of
nine sections: receiver, transmitter, modulation processor, speaker amplifier, volt­age regulator, frequency synthesizer, frequency selector, frequency display, and a
battery test circuit.

Two coding switches activated by two knobs on the front cover perform the
generation of the 12-bit frequency code. One switch generates the megahertz-part
of the code (26 steps between stops from 118 to 143 MHz) and the other switch
generates the kilohertz-part (40 steps from 000 to 975 kHz). The selected
frequency is shown in five digits (e.g., frequency of 135.925 MHz is shown as

FSG 5W

OPERATION MANUAL

‘135.92’) in a liquid crystal display (LCD) on the front cover. The LCD is lighted by
LEDs when pressing the ‘LAMP/BATT. TEST’ button on top of the case.

The FSG 5W also offers a transmit sidetone output as standard. Receive/sidetone
audio volume is adjustable in five steps. Accessory like voice operated PTT keys
can be supplied via the accessory socket with switchable 12 VDC from the radio’s
battery.

1.3 Modes of Operation

The transceiver may be operated in either of two modes; transmit or receive, as
selected by the Press-to-Talk (PTT) switch of the transceiver:

Transmit Mode - When the built-in or accessory PTT switch is depressed, the
transceiver will operate in the transmit mode.

Transmission will occur on one of the 1,040 channel frequencies according to the
indication of the frequency display, determined by the setting of the two frequency
switches.

Receive Mode - When the PTT switch on the radio is released, the transceiver will
operate in the receive mode. Reception on one of the channel frequencies, as se­lected by the frequency switches, will occur. The setting of the 'VOL' control deter­mines the audio level produced from the internal loudspeaker and/or the external
headphone. When the 'VOL' control is adjusted in the clockwise direction, the audio
level will increase.

NOTE:

In certain operating conditions, an external microphone-loud­speaker, a headset, or a voice operated PTT switch may be con­nected to the accessory socket of the transceiver.

In this case, the PTT switch of the external equipment operates the
transceiver via the accessory lead and connector.

When the connector of an external microphone or headset is
connected to the transceiver accessory socket, the internal
loudspeaker and microphone are disconnected and the VOLUME
control will control the audio level applied to the external
microphone-loudspeaker or headphone, as applicable.

Connection of only a headphone (without microphone) does not
disable the built-in microphone and loudspeaker.
