The Gain selector switch sets the microphone sensitivity maximum at “0

If a loud voice distorts the output sound, decrease the sensitivity by setting
the switch to the “−3 dB” position or less with the supplied screwdriver.
Note: The Input sensitivity setting switch is factory-preset to "0 dB."

• Holding down the Test mode ON/OFF switch for 1 second or more with
the supplied screwdriver causes the test signal to be transmitted. (This
condition is referred to as the Test mode.) Press this switch again to
return to the usual condition.
Note: Do not press the switch too strongly with a sharp-pointed object,
as this may cause unit failure.
• Once the power is turned off, the test mode will be released the next time the power is turned on.
• While in test mode, the receiver does not output audio signals even if it receives the radio signals from the
wireless microphone.
• For the test signal operation, refer to the S-D7000 Digital wireless system’s Setting software instruction
manual supplied with the S-D7802 Digital wireless receiver.
