Setting Sound Masking Level
This figure shows that the format of the panel for configuring masking. Z1 stands for
zone 1 and it is currently set to mute.
The initial value of Mute is displayed. To adjust the level, use the up
and down arrows while this screen is displayed.
Settings within the recommended ranges (see page 3) should
optimize speech privacy without excessive distractions. Generally,
set masking volumes toward the high end of the recommended
range and adjust according to site conditions and user preferences.
If possible, measure the results with a sound level meter and check
for the achieved sound pressure level. Adjust as necessary or judge
by listening in the area.
Setting Audio Input Levels
This figure shows the format of the panel for configuring the volume for input A. The
example shows Input A is level 6.
The system has one input for paging or music. If no paging and/or
music from the input is desired, set the audio volume level to mute.
The audio input levels are set in a similar way as the masking. Use
the arrows on the front panel to move left and right to find the input
A field. The input is enabled and level set using the up and down
arrows.
Lock/Unlock the Front Panel
If the configuration app was used to set the masking level, the app
could have locked the front panel. To unlock the front panel, hold
the left and right buttons for 5 seconds. The front panel display will
indicate that the panel has been unlocked. To lock the front panel,
repeat the process, hold the left and right buttons for 5 seconds.
If using the configuration app, the front panel will automatically
unlock when adjusting the masking level.
