The transmitter is now in SILENT mode and the display shows the Preset menu.
3. You can either select one of the Preset Subchannels from the Preset menu (section 3.6.1) or set the
carrier frequency in 25-kHz increments in the Frequency menu (section 3.6.2). The spacing between
Preset frequencies prevents any mutual interference.
A Preset comprises one or two Groups of carrier frequencies. Group numbers are shown under the
"GRP" label. Carrier frequencies are also called "Subchannels" whose numbers are indicated below the
"CH" label. The spacing between these frequencies is wide enough to prevent any mutual interference
(intermodulation). Presets make it much easier to design a multichannel system. They save time because
you do not need to calculate your own carrier frequencies and help you avoid intermodulation problems.
Each Preset has a one or two-character "NAME" relating to the country where the respective carrier fre-
quencies are allocated (e.g., "AT" for Austria, "US" for the USA, or "UK" for Britain). The Preset names
are sorted alphabetically.
When designing a multichannel system, make sure to use Subchannels within the same Group only.
Using Subchannels of different Presets and/or Groups simultaneously may cause intermodulation.
Some Presets may be approved in more than one country. To check which Frequency Group(s) is (are)
approved in your country, visit www.akgfrequency.at or contact your local regulation authority.
1. Push the jog switch briefly. The "NAME" label and the name of the currently active Preset will start
flashing.
If no Preset has been stored in memory, the 2nd line of the display shows "-- -- --".
2. To select the next Preset, turn the jog switch briefly to the right.
To select the previous Preset, turn the jog switch briefly to the left.
3. Having selected the desired Preset, push the jog switch briefly.
The "GRP" label and the number of the currently active Frequency Group will start flashing.
4. To select the next higher Frequency Group number, turn the jog switch briefly to the right. The high-
est number available will be followed by "00".
To select the next lower Frequency Group number, turn the jog switch briefly to the left. "00" will be
followed by the highest number available.
5. Having selected the desired Frequency Group, push the jog switch briefly.
"CH" and the number of the currently active Subchannel start flashing. Each Subchannel represents
one factory-preset, intermodulation-free carrier frequency.
6. To select the next higher Subchannel number, turn the jog switch briefly to the right. The highest num-
ber available will be followed by "00".
To select the next lower Subchannel number, turn the jog switch briefly to the left. "00" will be followed
by the highest number available.
7. Having finished your settings, push the jog switch briefly. This brings up the following screen:
9a If you want to save the selected carrier frequency, push the jog switch briefly. The setting will be saved
in memory and the display will change as follows:
9b If you'd rather not save the selected frequency, briefly turn the jog switch to the left or right.
This brings up the following screen:
