7.12 Scan mode
Your AE 7500 has an automatic channel scan, which can be used to observe all
channels consecutively.
First choose the mode (AM or FM). Adjust the squelch control to the point at which
the receiver should open or activate the ASQ.
Start channel scan
•
Briefly press the
SCAN key
•
Scan starts almost immediately by scanning all the channels upwards and the
SCAN icon
will appear on the LCD.
•
Scanning is stopped at each signal worth receiving and you can listen into the
conversation.
Without any action the scanning will resume after the communication on the channels
has stopped.
Stop channel scan
•
You can stop the scan at any time by pressing the
SCAN key
a second time.
•
Pressing the transmission button will also automatically stop the scan modus.
7.13 Transmitting
Before transmitting, you should check, that no other station is transmitting. This is
done best by pressing the
MONI key
. With the
PTT key
(
P

T
o
T
alk) on the side
of the microphone you can switch between receiving and transmitting:
•
Press
PTT key
to transmit.
The TX icon is shown on the LCD during transmission
•
Release
PTT key
again to switch back to receiving.
When transmitting, you can speak from a distance of about 5-10 cm into the
microphone. The modulation amplifier of your AE 7500 is sensitive enough and
enables you in most cases to speak with even more distance, depending on how
loud your voice is. An automatic regulator ensures that your partner always hears
your signal at the same volume. After pressing the PTT button, please wait about ½
second before you start speaking. Please remember - that different from GSM
phones - you share one channel common for transmit and receive, and your
transmitter and the receiver(s) on the distant side need a certain time to switch on.

Step Key
The channel spacing in the CB range corresponds with the usual standard of the
international 10 kHz spacing, where some channel are spaced 20 kHz instead of
10kHz. You can change the frequencies with the
CHAN control
on the readio or with
the
UP/DOWN keys
on the microphone by 1 channel. With the
STEP key
you can
change the displayed frequency also in steps of 500 Hz to for finer tuning.
Example:
channel1, 26.965 MHz
•
Press the
STEP
key
•
Now you can tune with the
CHAN control
between
26.9600
and
26.9695
MHz
.
•
You also have the
CLARIFIER
for further fine tuning.
According to the regulations for CB radio the transmission frequency is unchanged.
NOTE: When stepping in 1 kHz increments, you are limited to tune within a 10 kHz
frequency range.
