Parameters:
The screen initially displays
Starting a Scan
Press the INC key to start a scan. The receiver searches every possible channel.
A full scan takes about 8 seconds and the receiver displays the quietest frequency once the scan has completed.
Accepting the Frequency
Press the DEC key to load the selected frequency into the receiver.
Discarding the Frequency
Press the MENU key to discard the selected frequency. The receiver exits to the
discarding the frequency.
Blocking Frequencies with RF Interference
Press the INC key to restart the scan. However, when the scan restarts, instead of performing an entirely
new scan, it averages the current and previous scans. Frequencies that are temporarily occupied are
remembered in the final selection, allowing the receiver to block frequencies that contain intermittent RF
interference.
Starting a New Scan
Repeatedly press the MENU key until you have stepped all the way around the menu back to the
Receiver Frequency Scan

Best Practice: Scanning for a Low Noise Frequency

The easiest way to remember the proper way to scan is to push the keys from right to left:
1. Repeatedly press the MENU key until
2. Press the INC key to start the scanning process. Ensure the transmitter is 'OFF' before starting the scan.
3. Press the DEC key to load the selected frequency into the receiver. The menu advances to the next item.

Best Practice: Finding the Quietest Frequencies for Multiple Transmitters

1. Turn all transmitters 'OFF' and perform a couple of scans.
2. Accept the quiet channel by pressing the DEC key.
3. Turn 'ON' the first transmitter and tune it to this channel.
4. Place the transmitter at least 20 feet (6 meters) away from the scanning receiver.
5. Perform another pair of scans.
NOTE: At any time in this page, the MENU key may be pressed to exit. This will also clear out any change and
revert to the previous selection.
Since the most recently selected frequency is now occupied, the next receiver to perform a scan finds the next
quietest frequency. Repeat this procedure for each additional transmitter. This procedure assumes that all of the
transmitters will be operating in the same block.
This page allows you to scan an entire block of channels and quickly choose the quietest channel
