Figure 7.2 Service tasks
Instrument disassembly
—
Use a TX10 torx screwdriver
to remove all four screws from
the case bottom; set aside the
screws. Hold the case bottom near
the upper screw holes;
carefully begin to lift the
case top to separate it from
the case bottom. Continue to lift the case top straight up to remove it and to
avoid unintentionally loosening the sensors.
Complete any needed service, then replace the case top.
Speaker dust barrier replacement
—
Use your finger or needle-
nose tweezers to peel off the
dust barrier; discard the used
barrier.
Scrape lightly across the
paper to the barrier's edge;
gently lift to expose a
portion of its adhesive back.
Peel the barrier from the
sheet.
Guide the new barrier — adhesive side down — onto the case
top, positioning it over the speaker.
Place your thumb over the dust barrier, press and hold for five
seconds to seal the adhesive.
Sensor water-barrier assembly replacement
Note . The sensor water-barrier assembly consists of two parts: the filter and its gasket. Replace both items at the same time.
Inside the case top, grip the
gasket and underlying sensor
filter with the needle-nose
tweezers; peel to remove.
Remove any remnants of
the adhesive, filter, or
gasket.
Clear away any dirt, dust,
or debris.
Place the filter sheet on the work surface.
Using tweezers, scrape lightly across the paper to the filter's
edge; gently lift to expose a portion of the adhesive back.
Grip the filter lightly with the tweezers and peel it from the
sheet.
