Operating the A20-RX
The A20-RX is easy and quick to setup.
Country
The country of operation determines the available Bands and Frequencies. The country setting also determines the TV channel
mapping of preset frequencies in the UHF band. It is important to set the country before transmitting and receiving RF. Country
should be reset anytime you change your location to another country.
To Set Country:
1.
Enter the Menu.
2.
Select Settings to enter the Settings sub-menu.
3.
Select Country.
4.
Use the Left and Right buttons to locate the current country of operation.
5.
If the country is not listed, use the ‘Other’ option.
6.
Press the Center button to select the country and return to the Settings sub-menu
Modulation
Modulation can be set to Standard (Std) or Long Range (LR) per receiver channel. Set Modulation in Menu > Settings > Modulation.
Compared to Standard Modulation, Long Range Modulation has better sensitivity. This increased sensitivity results in better range in
challenging RF environments.
The Modulation setting must match between the A20-Mini or A10-TX and the A20-RX in order for the transmitted signal to be
received.
SpectraBand
The A20 Digital Wireless System incorporates SpectraBand technology. This allows operation across a frequency range of 470 -
1525 MHz making it possible to find available frequencies wherever you are.
To Set Band:
1.
Press the Center button to enter the Menu.
2.
Select Frequency.
3.
Select Band.
4.
Use the Left and Right buttons to find the band of frequencies to operate within.
5.
Press the Center button to select the Band.
6.
After selecting the Band, Set is highlighted. This is to confirm the change of Band. Changing Bands interrupts audio and
changes the frequencies assigned to Rx channels
Select Set to confirm the selection or select the back arrow to cancel the Band change and return to the Frequency me
nu.
Frequency
Because the A10 and A20 digital RF transmission is inherently immune to intermodulation, multiple A10 and A20 Digital Wireless
systems can be used simultaneously on nearby adjacent frequencies without worry of intermodulation interference. Systems can be
used together when separated by at least 400 kHz. When operating in the 902-928 MHz Band, it is recommended to separate
channel frequencies by at least 1 MHz.
