command has the higher priority and will override the DIP switch settings. The unit will default back to the DIP switch settings when
the power is cycled. (Excluding No. 7 of DIP switch1)
■ Basic format
The serial command employs a common format to the commands of both from a control device to this unit and from this unit to a
control device, and the format is categorized into 3 patterns as follows:
When no parameter:
"$" as a starting character, command, the control code, "CR" and "LF", as the termination character.
When a single parameter:
"$" as a starting character, command, colon, 1st parameter, the control code, "CR" and "LF", as the termination character.
When the two parameters:
"$" as a starting character, command, colon, 1st parameter, colon, 2nd param
• All of $, CR, LF, : (colon) are fixed single byte, and the command part is fixed 3 bytes.
• The length of the parameter part is basically single byte. As an exception, only the 2nd parameter is 2 bytes for the volume setting
command.
• If a command containing a failure in the command part or format is transmitted to this unit, $ER1[CR][LF] is returned from this
unit.
• If a command containing a failure in the parameter part is transmitted to this unit, $ER2[CR][LF] is returned from this unit.
• When a timeout error occurs on the receiving timer (30 seconds) between each byte, $ER3[CR][LF] is returned.
Note:
• When commands are successively transmitted, keep 300 ms or more between successive commands that are transmitted to this
unit.

Troubleshooting
Symptom
No reception
Cause/solution
Does the POWER LED light?
>>
Check the connection between the receiver and the amplifier.
Check the power of the amplifier is turned on
Is the power of the microphone turned on (Is a battery loaded)?
>> Turn on the power of the microphone (load a battery) to put it
into the transmissible state.
Does the reception LED indicator MIC1 or MIC2 light?
>> If the microphone is not normally receivable, the reception LED
indicator does not light.
The audio output of LINE IN is not provided.
>> Is audio output of the device connected to LINE IN ready to be
provided?
No sound generated
No audio output of the microphone or LINE IN is provided.
>> Is n’t the page mute signal input provided to this unit?
If the page mute signal input is provided, the audio output from this
unit is muted. The 3 LEDs of this unit light yellow while the page
mute function is activated.
Is the volume setting equipped in this unit set to the lowest level?
>> The volume of the microphones MIC1 and MIC2 and LINE IN
equipped in this unit can be adjusted by K-STD14 and through
external communication control.
The volume of the mixing output fluctuates.
>> When the microphone override function is active, an audio input
to the microphone (MIC1 or MIC2) attenuates the audio level
provided to LINE IN.
Audio interrupted
Is n’t the feedback blocker activated?
Adjust the speaker output to the lower level so as to avoid the
feedback.
