6 Using the wireless receiver 2-2-2. Channel scanning For an interference- free operation, a cleaner channel might be necessary if the current one receives too much interference. To operate the scanning: 1 Press ▼(down) or ▲(up) button to make the frequency icon appear on the bottom. 2 Hold SET button until this icon flashes to denote readiness for setting. 3 Press ▼(down) or ▲(up) button to find and locate a clear, interference- free channel. 4 After a channel is chosen, press SET button or wait 5 seconds to store the setting. 2-2-3. Squelch (SQ) setting When interference is encountered try reducing the sensitivity of the receiver, thus less susceptible to interference. To operate the squelch setting: 1 Press ▼(down) or ▲(up) button to turn to the squelch setting page. 2 Hold SET button until this icon flashes to denote readiness for setting. 3 Press ▼(down) or ▲(up) button to select a new squelch level between 01 and 10. The default level is 01. 4 After a level is chosen, press SET button or wait 5 seconds to store the setting. Since increasing the squelch level will also reduce the reception distance, it’s recommended to choose the lowest level that can eliminate the interference. If this still does not solve the problem it means this frequency is not suitable. Adjust the squelch back to its default level (LE-01) and use the scan function to locate a clear, interference-free channel.
