AR300/AL300 Operation
Setting a Group and Channel Manually
The AR300 receiver contains 320 selectable channels for N and U band, and 71
selectable channels for E band. All channels are organized into a series of groups.
Each group contains channels that are compatible for simultaneous use. When using
multiple systems, each system should be assigned to the same group in order to
maximize the number of compatible channels. Each group is designated with a letter,
followed by the group channel number (0–9) which is displayed under the “GROUP”
icon in the AR300 LCD display.
To the right of the Group and Group Channel number is the read out for the Absolute
channel number. This three-digit Absolute Channel number corresponds to the exact
channel from the entire channel plan. That Absolute Channel number is shown on the
AL300 transmitter’s LCD display.
The AL300 displays the Absolute Channel number it its LCD for a few seconds, and
then the display shuts off to preserve battery power. You can also see the transmitters
Absolute Channel number by switching the Mute on. In addition, the AL300 will also
display the Absolute Channel number briefly when the power is shut off.

again until the Absolute Channel number flashes. Then, turn the EDIT controller

infrared channel data to the AL300. Have the transmitter ready in your hand with
