13.1
Tone Selection
The sontels have 32 different tones that can be selected by
the DIP swirtches on the sounder pcb. The tone table on
page five shows the switch positions for the 32 tones and
which tones are available for the second and third stages. To
operate the sontel on stage one simply connect the supply
voltage to the normal supply terminals (+ve and –ve for DC
units, L and N for AC units).
13.2
Pulse Tone Operation
The BExTS110D Sontel has two modes of operation,
continuous tone operation and pulsed tone operation.
To select continuous tone operation the pulse tone header
pins should not be shorted. In this mode the output tone will
be as per the tone table.
To select pulse tone operation, the pulse tone header pins
should be shorted. In this mode of operation the selected
tone pattern will pulse on and off following the telephone
input signal.
Note if pulsed tone operation is selected it is advisable not to
select any of the intermittent tones, such as tone 11.
13.3
Volume Control
Warning - High noise levels above 85dB(A)
during operation. High levels of noise may
cause hearing loss, wear suitable ear
protection when equipment is in operation.
The output level of the BEx sontel can be set by adjusting the
volume control potentiometer (see Fig 9). For maximum
output, set the potentiometer fully clockwise.
