A10-RX User Guide
Basic Operation
Frequency Selection
The A10 Digital Wireless System operates in the UHF frequency band from 470 to 694 MHz.
The A10-RX can tune across the entire range of the system.
Because the A10 digital RF transmission is inherently immune to intermodulation multiple A10
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.
Manually Setting Channel, Sub Channel, Frequency
To simplify frequency selection, frequencies are divided into channels and sub channels. The
specic frequencies corresponding to channels and sub channels depends on the setting of the
TV Channel Mapping (Main > Settings > TV Ch Map). Three options are available, 6, 7, and 8
MHz spacing, X, Y, and Z respectively. These three settings generally correspond to three main
geographic regions, the Americas, Australia/New Zealand, and Europe, respectively. For more
information, see Channel Assignments by Region.
• Channel - corresponds to broadcast television channels used in a geographic region.
Depending on the selected channel mapping, channels cover 6, 7, or 8 MHz.
• Sub Channel - channels are divided in 400 kHz increments called sub channels to speed up
frequency selection. The number of sub channels depends on the channel mapping selected.
• Frequency - specic frequencies within the receivers tuning range can be selected in 25
kHz increments. When a selected frequency does not correspond with a channel/sub channel
mapping, an asterisk character (*) is shown in the display adjacent to channel/sub channel
assignment below the frequency shown.
To change TV channels:
1. Use the Left button to highlight the TV Channel.
2. Press the Centre Menu to select the TV channel.
3. Select the sub channel until the desired sub-channel is selected.
ª Remember, for a given channel / sub channel, the actual frequency will change depending on
the TV Channel Mapping setting.
See the Frequency Tables in this guide for a complete list of frequencies corresponding to the
channel and sub channel selections.
Frequency Scanning
The frequency scanning tool uses the radios in the A10-RX to measure and display RF activity
within the system’s tuning range. This allows a user to nd frequencies with low RF activity
suitable for system operation. The scan tool operates over the full 224 MHz bandwidth of the
receiver. Enter the scanner from the Selection Menu Main > Scan.
ª Audio from channel 1 and channel 2 is muted when the scan tool is active.
To initiate a scan, press the >> button. The scan will start, working from lower frequencies
to higher frequencies. The cursor can be seen to move along the screen denoting the current
position of the scan. The scan can be stopped by pressing the Left button.
Selecting the > button allows the user to manually step through in 400 kHz steps at a time.
Selecting the << button allows the user to automatically scan backwards, and similarly selecting
the < button allows the user to manually step lower in frequency in 400 kHz steps.
