Input Sensitivity Adjustment
The X

offers five (
)
) input gain settings

The adjustment runs in
$(
dB steps from

!(
dB
*
This wide range of adjustment allows the X

to accept input
voltages from

V
*
Adjustment is made by installing a jumper across the
associated input voltage/pin location
*
Refer to the illustration on the reverse side of
this document prior to setting the input sensitivity

To change a frequency
,
simply remove the resistor SIP and replace it with
the appropriate SIP value to achieve the desired frequency

Any combination of the available
frequency SIP’s may be used
