Paging Level
The ZX3 module has controls for adjusting the audio level of each zone
independentl
y.These serve as master level controls that allow for overall
zone control. Setting the initial volume to half is a good starting point. If
the speakers have their own level control, then the installer will have to
determine the proper setting for each speaker depending on the
a
pplication. Each level control includes an LED indicator above it to
indicate if the zone is active.
Music Level
The UTI312 has two background music input level controls. Once the
page level has been adjusted, set the music level control to the desired
background music level.
Tone Level
The Tone Level control sets the level for Tone Trigger 1 and 2,
pre-announce tone, confirmation tone, and code call tones.
Night Ring Level
The Night Ring Level control sets the level for the Night Ring tone.
Limiter Threshold
Because everyone doesn’t speak at the same level, the UTI312 includes a
limiter threshold control that prevents loud voices from booming out of
the paging system’s speakers. The limiter restricts the input signal to a
preset level regardless of the input level. To set the limiter, follow the
directions below.
1. Turn off the limiter by rotating the control fully counterclockwise.
2. Hold the telephone handset in a normal position and speak in a
normal v

y into the mouthpiece. Adjust
the limiter control until the limiter active LED starts to
come on.
The ZX3 module level controls can be adjusted without disturbing the
limiter adjustment.
