By long-pressing the LCD illumination toggle key ( 13 ) [
DW / B
], the LCD back-light color
is switches between orange and blue.
7) Modulation selection [ Mode ]
The MX-8 can operate in AM or in FM modulation. However, some versions, e.g. MX-8 c opera-
te in FM only.
If the unit accepts also the modulation type AM on the actual channel, you can toggle it by pres-
sing the key ( 7 )
[ Mode ]
between the modulation types AM and FM. The selected AM mode
will be indicated by the symbol "AM". If the unit does not accept the modulation type AM on the
actual channel, you will only hear a receipt tone, but it remains on the modulation type FM.
If the unit is set to AM on the actual channel, and you select another channel, on which the
AM mode is inhibited, the modulation changes automatically to FM mode. If you select once
more another channel, on which the AM mode is allowed again, the modulation switches
automatically to back to AM mode.
With the model type "
MX-8 uk Multi Norm
", you can toggle between the EU band and the
UK band, which is indicated by symbol "EU" or "UK", by pressing the key ( 7 ) [
Mode
] If the
actual model type of the MX-8 is the "MX-8-uk", you can only work in FM mode. By pressing
the key ( 7 ) [
Mode
] you can toggle the unit between the EU band and the UK band, which
is indicated the symbol "EU" or "UK". When being switched on af ter a disruption of the sup-
ply source the unit works on channel number 9 in the UK band. The CB band EU consists of
the 40 CEPT channels. The CB band UK consists of 40 channels starting from 27.60125 MHz
to 27.99125 MHz. It is permitted only in Great Britain. After switching it off, the unit stores the
last channel of the actual band and also of that band, which is actually not in use, as long as
the power source remains connected.
8) Version Selection
The MX-8 type distributed in Great Britain is called "MX-8-uk Multi Norm". The three different
versions "8000uk", "4040" and "8040" can be switched by the end-user .
To enter the version selection mode keep pressing the Priority Channel 9/19 key ( 14 )
[ CH9/19 ]
while turning the radio on. Release the key ( 14 ) when one of the three digit s

will start blinking in the display . No other symbols will be present in the display . The
digits represent the different versions ( 4: 8000uk, 1: 8040 and 2: 4040. When you see a digit
blinking in the display you can select a version by pressing shortly the Channel 9/19 key ( 14
)
[ CH9/19 ]
until the desired digit appears in the display. Every pressure increases the num-

Great Britain only. In other countries the version "8000uk" is not allowed.
> In the position "4040" the unit works only on the 40 CEPT channels, but it allows on every

AM 1 W. In the following countries the unit is allowed to be used on every channel in both
modulation types FM and AM: Belgium, France, Italy, Netherlands, Portugal and Spain.

To transmit, depress and hold the key ( 4 ) [
PTT
] on the microphone ( 1 ). On the LCD, the
symbol "TX" appears, and the bar meter at the bottom of the display shows the relative trans-
mit signal strength. For best quality , speak normally at a dist ance of 2 - 4 inches. S peaking
too loudly will cause distortions and make the signal dif ficult to understand. While the set is
in the transmit mode there is no key entry possible and the receiver is muted. On completion
of the transmission release the PTT key ( 4 ) and the set will revert to receiving mode.
10) Call tone
If you press the transmit key ( 4 ) [
PTT
] and the call key ( 5 ) [
SIGNAL
] on the microphone
( 1 ) at the same time, a call tone will be transmitted and can be heard only by the p artner sta-
tion, provided it is switched on the same channel and the same modulation type.
11) Priority Channel 9 / 19 [ CH9/19 ]
The MX-8 contains the priority channels 9 and 19. Priority channel 9 is selected by pressing the
key ( 14 ) [
CH9/19
] once. To set priority channel 19, press the key ( 14 )
[ CH9/19 ]
twice. When
a priority channel is set, the channel and the frequency will blink in the display and all function
keys including the rotary channel selector are disabled. Only transmission and activation of the
VOX function are possible.
To return to the previous channel, press the key ( 14 )
[
CH9/19
] once, if priority channel 9 has been selected, or twice, if priority channel 19 has been
set. Once returned to regular mode, all functions will be enabled again.
12) Channel scanning [ SC / KL ]
If this function is active, the unit looks for occupied channels. As this function does not work with
open squelch, set the squelch control ( 8 ) [

which is indicated by the extinction of the scan symbol "
SC
".
To stop scanning, press the scan key ( 8 ) [
Scan
] once again. Scanning also be stopped by
pressing the channel selector ( 2, 3 ) or PTT (4) key, or by turning the rot ary channel selec-
tor ( 9 ). Then, the scan symbol "SC" will disappear from the display , and the actual channel
will be that one, on which the channel number was just st anding at the moment of deactiva-
tion of the scan function.
13) Dual watch function [ DW / B ]
This function allows you to montitor two channels concurrently. Before activating this function
make sure that the squelch is closed on free channels.
