Procedure for Reusing the Same Frequency 2/2
2. Use "Code" (recommended)
This function prevents interference between channels sharing the same frequency. By performing Code settings,
receivers and transmitters can be paired, muting radio signals on the same frequency that may exist in the surrounding
area. Code setting is effective when the encryption function is not set.

Figure a. Even if the code is the same, if the power for both microphones
is ON, radio interference will not occur. (Since the stronger radio
signal takes precedence, only the microphone within the
immediate area is reproduced.)
Figure b. If power to either area is turned off when Figure a conditions
exist, Receiver 1 may mistakenly receive MIC 2 audio. (Since
the code is the same, it would be impossible to distinguish
between MIC 1 and MIC 2.)
Figure c. If different codes are set in Area 1 and Area 2, mistaken
reception will not occur even if power to the microphone
for either area is turned off. (Since microphones in both
areas differ in code, audio is muted.)

NOTE: Since the encryption function, which enhances security, also requires pairing of a transmitter with a
receiver, code setting is unnecessary if the encryption function is used.
