The MUON command allows inserting a silence between two playback phrases. The command can be input
when the NCR signal on the target channel is at a “H” level.
Set the silence time length after inputting this command. It can be set for each channel. The MUON
command allows specifying multiple channels at one time. Setting any bit(s) from CH0 to CH3 to “1” plays
silence on the corresponding channel(s).
Channel settings
Channel
CH0
Setting this bit to “1” inserts a silence on channel 0.
CH1
Setting this bit to “1” inserts a silence on channel 1.
CH2
Setting this bit to “1” inserts a silence on channel 2.
CH3
Setting this bit to “1” inserts a silence on channel 3.
Be sure to set the channel setting bits( CH0-CH3).
As the silence length (M7–M0), a value between 20 ms and 1024 ms can be set at 4 ms intervals (252 steps in
total).
The equation to set the silence time length is shown below.
The silence length (M7–M0) must be set to 04h or higher.
