•
On a free channel NO basic receiver noise should be audible in the speaker
(Squelch = ON).
•
To check the receiver's squelch circuit, set squelch switch (
2
) to 'SQ OFF' posi-
tion. On a free channel, basic receiver noise with constant volume should be
audible (only at an interference free location).
•
For receiving normal communication, the squelch switch (
2
) should be in the
"SQ" position. Receiver noise, weak signals, and interference signals are
blocked, the power consumption of the radio is reduced.
•
If the squelch switch (
2
) is set to the 'SQ OFF' position, maximum receiving radio
range is obtained and very weak signals can be received satisfactorily, but with
noise content.
•
To change the operating frequency, adjust with MHz- (
7
) and kHz-switches (
8
)
the desired new frequency readable on the display (
6
).

Operation in the Transmit Mode
To operate the transceiver in the transmit mode, proceed as follows:
•
Please, keep radio discipline. The channel must be clear before transmit-
ting.
•
Verify that the display (
6
) shows your desired operating frequency.
•
Hold the transceiver
FSG 5W
in the left hand, with the microphone area (
10
) as
close as possible to the upper lip.
This technique is necessary because the noise cancelling feature of the micro-
phone favors sound close to the microphone and discriminates against sounds
away from the microphone.
•
Depress and hold the press-to-talk (PTT) switch (
9
) during transmission.
•
Speak loudly, slowly and distinctly into the built-in microphone (
10
) from a dis-
tance of 3 to 5 cm.
•
When message is ended, release the PTT switch (
9
) in order to clear the
channel.
•
The transceiver is now operating in the receive mode.
•
To change the operating frequency, set with MHz- (
7
) and kHz-switches (
8
) your
new desired frequency readable on the display (
6
).
During transmit operation a part of the decoupled RF power modulation signal is fed
as "Sidetone" to the ear/headphone output of the accessory socket (
1
). The built-in
speaker is switched OFF during transmitting. Therefore sidetone is only audible
when the radio
FSG 5W
is operated with an ear/headphone. Transmit sidetone
audio volume corresponds with the receive volume setting of the transceiver.
IMPORTANT!
The transmitter output amplifier is protected against any antenna mis-
match by a directional coupler circuit. Transmitting without any antenna
will therefore not harm the output amplifier.
Significant antenna mismatch will reduce dramatically the range of
transmission.
