Channel scan function
Before using the wireless microphones, you should use the channel scan
function to check for interference and the frequencies of channels that are
already in use, so that they may be avoided when selecting groups and
channels.
To activate this function, select the group you wish to scan and press the
CH, the plus (+) and the minus (–) buttons simultaneously. The reception
channels within the selected group will be scanned automatically.
The RF lamp lights up whenever signals above 15dB µ are detected in the
frequencies within the wireless channels receivable on Sony receivers. The
scanning will also stop on any frequency containing a tone signal of
32.768kHz, provided the RF signal is stronger than the set muting level.
Whenever the scanning stops on a particular frequency, that particular
frequency is being used.
To restart the scanning process after it has stopped on a particular
frequency, press the CH, the plus (+) and the minus (–) buttons
simultaneously.
Notes
• Once the channels in a group have been scanned twice, the scanning stops
automatically. If you want to stop the scanning process, press any button.
• If the interference is very strong, the scanning may stop on a frequency
that differs from the actual interference frequency.
