CB radio AE 6120 VOX
Important information
Please read these instructions carefully before installing and operating your
AE 6120 VOX radio.
Please use only the original microphone on the CB radio, otherwise the proper
functioning of the VOX hands-free function can not be guaranteed.
The VOX sensitivity is preset for use in moderately loud vehicles.
If your vehicle is very silent you can increase the VOX sensitivity, and the
VOX function will trigger with softer speaking.
For optimal results mount the microphone 45 – 70 cm away and directly facing
the driver.

Installing the device
When installing your radio in the vehicle, make sure you do not damage any wiring or other vehicle components that may be hidden in the place of installation.
4.1. Installing the antenna
For the ultimate performance of your CB radio, it is crucial that you use a
high-quality antenna.
-
Only use antennas that are suitable for the frequency range of 26.565 – 27.405 MHz.
-
Connect the antenna to the antenna socket on the rear of the device with a PL259 plug.
-
For the best range, mount the antenna as high as possible to ensure unobstructed transmission in all directions.
-
The operation of standard CB radio mobile antennas requires a good conductive connection to the metal mounting surface.
-
There is special “no ground plane” (NGP) antennas for camping vehicles or trucks with plastic superstructures.
However, they do not work directly on metal surfaces. -
Do not use the radio to transmit messages without a connected antenna as the radio can be damaged or destroyed.
Operation
5.1. Turning on and adjusting volume
To turn on the radio, short press the turning knob. To turn off the radio,
long-press the knob.
To increase the volume, turn the volume knob clockwise.
5.2. Choosing the right country setting
The AE 6120 VOX radio supports all current European CB radio standards. The
factory default setting is “E”.
Procedure for switching the country setting:
- Turn off the radio
- Press and hold down the MODE button (AM/FM)
- Now turn on the radio
- Release the MODE button
- Now use the UP/DN buttons to select one of the country settings “d, EC, Po, UK, E, I2, In”
- Turn the radio off and then on again to confirm your selection. The radio uses the selected country setting from now on.
5.3. Country setting and use

12| 12| FM 36 / 4 watts
FM 36 / 4 watts
In| In| FM 27 / 4 watts
FM 27 UK / 4 watts
You can switch the country setting at any time as described above. The country setting remains active until you select a different one.
5.4. Selecting a channel
- If you short press the turning knob CH, the channel symbol will start blinking.
- Turn the knob or use UP/DN on the microphone to change the channel
- Press the knob CH again to confirm your selection
5.5. Squelch
The AE 6120 VOX radio has 2 squelch options
- Automatic squelch (ASQ)
- Manual squelch (SQ)
Each suppresses the channel noise by muting the speaker.
Squelch only unmutes the speaker for the received signal to be heard if
certain criteria are met.
5.5.1. Automatic squelch (ASQ)
Automatic squelch continuously evaluates the noise level. If a signal is
received it decreases and the ASQ unmutes the speaker.
To turn ASQ on, long-press the SQ/ASQ button the AQ symbol appears on the
display.
Use the turning knob or UP/DN buttons to select the desired
ASQ level. Press SQ/ASQ again or wait 5 seconds to confirm your selection.
ASQ has 9 configurable levels, with Level 1 being the most sensitive.
Advantage: the highest sensitivity and thus the greatest range.
Disadvantage: can be disturbed by interferences such as sunspot activity,
other electronic devices, etc., so that the speaker is activated even if no
signal is received. In this case, manual squelch or tone squelch should be
used.
5.5.2. Manual squelch
The squelch suppresses the channel noise. To set the manual squelch, short
press SQ/ASQ.
Use the turning knob or UP/DN buttons to select the desired squelch level.
Press SQ/ASQ again or wait 5 seconds to confirm your selection.
The further you turn the control, the stronger a received signal has to be to
open the squelch. Usually, the squelch is set to just barely mute the speaker.
The manual squelch can be set in 34 levels.
Advantage: Manual squelch can be set so that only close-range stations can be
heard.
Disadvantage: Manual setting is required. If the squelch is mistakenly set too
high, it decreases the reception sensitivity and thus the range.
5.6. AM/FM mode selector
AM or FM modulation can be selected by pressing the MODE button.
The current setting is displayed on the LCD screen.
If a channel from 41 to 80 (only available in region mode d) is set, the
device switches to FM mode regardless of the setting on the lower channels.
When you switch back to channels 1 to 40, the AM mode is restored, if it was
previously selected.
The bar graph on the display shows the signal strength (S-values) in 8 levels
during the reception.
5.7. VOX function
Long press the MODE/VOX button to switch the VOX function on or off. When the
VOX function is activated, the radio automatically switches to transmission as
soon as it detects speech. You no longer need to pick up the microphone to
transmit messages.
The active VOX function is indicated by the symbol in the display.
5.7.1. VOX sensitivity
The VOX Level is used to select the volume level above which an automatic VOX
transmission is activated.
Long press the EMG/MENU button and then use the UP/DN
keys to select the submenu “VOX L”.
1 = low sensitivity, VOX only reacts to very high volume levels
9 = high sensitivity, VOX already reacts to very low volume levels
The default value is level 6.
5.7.2. VOX delay
Long press the EMG/MENU button and then use the UP/DN
keys to select the submenu “VOX T”.
The VOX delay function sets the time after which the automatic transmission
mode is disabled if no speech is detected:
Level | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
---|---|---|---|---|---|---|---|---|---|
Time (sec) | 0.5 | 1.0 | 1.5 | 2.0 | 2.5 | 3.0 | 3.5 | 4.0 | 4.5 |
There are 9 configurable delay levels. The default value is level 4.
5.8. Emergency channel 9/19
The EMG button is used to switch through CH 9, CH 19, and back to the
previously selected “normal” channel. Simply press the button repeatedly.
5.9. Main menu
Long press the EMG/MENU button to enter the main menu.
Select your desired submenu with the UP/DN keys and confirm your selection by
pressing the turning knob.
You can make the following settings:
Display| Description|
Selection
---|---|---
KEY BP| Key tones| ON / OF
ROG BP| Roger Beep| OFF or select 1-6 tones
SCM| Scan settings| S9 = Squelch Scan T1 = Time Scan
VOX L| VOX sensitivity| selectable in 9 levels
VOX T| VOX delay| selectable in 9 levels
REGAIN| RF Gain| selectable in 16 levels
TOT SET| Time Out Timer| Cuts of transmission after 0-10 min.
RESET| Factory reset| Resets the radio
5.10. S-Meter
The S-meter shows the current signal strength. The strength is indicated by
the symbol in the lower left of the display.
The more bars are displayed, the stronger the signal.
5.11. Scan mode
Your AE 6120 VOX radio has an automatic channel search that can be used to
view all channels one after the other.
-
Long press the UP or DN button for 7 seconds. A beep tone can be heard and a dot between the 2 digits of the channel appears showing the active scan function
-
Scanning stops every time a signal is received and you can listen in on the conversation.
If no action is taken, the scanning process continues after either the communication on the channel has ended or after approx. 5 seconds of observation time, if the communication continues. -
The search process can be canceled at any time by pressing the EMG or PTT button (on the microphone).
5.12. Resetting to factory settings
To reset the device to its factory settings, proceed as follows:
- Long press the EMG/MENU button to open the main menu
- Select “RESET” from the menu. “RESETS” starts blinking on the display
- Press and hold the tuning knob until the blinking stops
- Now the radio will restart automatically
In most cases, the radio functions have now been restored.
External speaker
It is advisable to connect an external speaker depending on the ambient noise.
Typical, commercial radio speakers with 16 ohms impedance and a minimum power
of 2-4 W can be used.
WARNING: The sound output mode of the machine is BTL output, and the two
pins of the speaker cannot be connected to the ground net or the machine
shell! Otherwise, there will be a large DC current flowing through the
speaker, which will burn the speaker and components.
We recommend using the Albrecht speakers CB-150 or CB-250 for best
compatibility.
