The
Low Battery Indicator flickers a “battery icon” when the
battery power is low and the ON/OFF Button is depressed. Replace
the

The
SENS Range Switch inside the battery compartment has 3 positions:

With the switch in
the High position, the LD-8’s sensitivity
is highest (for listening to small leaks). With the switch
in the Low position, the LD-8’s sensitivity is lowest
(for listening to loud leaks). |

The Out of Range Indicator flickers a “ ” icon
when the sound level display exceeds 99. Move the SENS Range
Switch to Medium or Low to re-scale the two-digit display to
a lower range. Each SENS Range Switch position is 10X higher
or lower in sensitivity then the adjacent position. |
