Direct channel 9 access

Transmitting and correct use of microphone
With the transmission button (Push To Talk) on the side of the microphone you can
switch between receiving and transmitting:
Press PTT button to transmit.
The display shows TX .
Release PTT button again to switch back to receiving.
Before transmitting the first time, make sure that the MIC gain potentiometer above
the mic socket is in the full clockwise position. When the transmission PTT button is
pressed, you can speak from a distance of about 5-10 cm into the microphone. The
modulation amplifier of your AE 5090 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.
It is best to test the best distance from the microphone for yourself with the help of
another station.
Bar graph switching between POWER and MOD
During transmitting, You will normally see the bar graph of the S-meter in the
display as indicator for Your transmitter output power.
Alternatively You may now switch with the MOD-PWR button to Modulation
display instead of Power display. The display shows MOD now.
This will show your modulation volume in the display and will help to check and
adjust the microphone.
You can toggle with the switch between MOD and POWER display
MIC Gain setting
For dynamic microphones, the full clockwise position of the MIC gain knob above
the mic socket will be optimised. If You should use amplified microphones, or if You
speak with a very loud voice or in high surrounding sound environment, we
recommend to readjust the potentiometer more to counter clockwise positions.
