AUDIBLE ALARM Setting – when set to ON (Figure 22), provides an audible tone
whenever the unit detects a problem with itself, or with an externally connected
battery pack. In the OFF setting, the audible tone is silenced.

SENSITIVITY Setting – press the SETUP push button to advance to the Sensitivity
function. This feature adjusts how the S Type reacts to input voltage waveform
distortion and momentary power fluctuations. It allows you to adjust the sensitivity
of the S10 and S15 to LOW , MEDIUM , and HIGH (Figure 23) using the SETUP
and Up/Down Arrow push buttons. The Sensitivity adjustments have the following
value:
HIGH Sensitivity – should be used when the connected equipment is sensitive to
momentary low voltage or brief power fluctuations. In HIGH Sensitivity the unit is
very sensitive to voltage distortion and is, therefore, more likely to switch back and
forth to battery power than it would under a MEDIUM or LOW sensitivity setting.
MEDIUM Sensitivity – is the default setting suitable for most situations.
