Maintenance

Always keep the instrument in its pouch when
not in use, make sure to insert the instrument
in the pouch the correct way.
Especially the humidity probe is sensitive and
should never be touched.
The LCD lens. Be careful not to scratch this
lens. Take care not to break the glass lens.
Do not subject the Dewcheck to a strong impact
or to extreme temperatures.
We suggest cleaning the lens only with a soft
dry cloth - such as a cloth made for cleaning
eyeglasses.
Clean the plastic surfaces only with isopropyl
alcohol (rubbing alcohol) and a soft dry cloth.
Never force a connector into a port if the
connector and port do not join easily. Make sure
that the connector matches the port and that
it's properly aligned and undamaged before you
attach it.
Keep the Gage away from extreme heat. Don't
leave it on the dashboard or in the trunk of a
car or near a heater. Heat can damage the
screen, the plastic case and internal parts.
Don't leave the Gage where it is extremely dusty,
damp or wet. Dust and moisture can damage
the Gage and cause it to malfunction. The Gage
is not waterproof and may not be submerged.
If the battery symbols flashes ( see chapter 3)
the batteries need to be exchanged.
Use a Phillips-type screwdriver to unscrew the
lower screw at the back of the instrument.
Lift the battery-cover up until it "clicks
remove the cover. (the "click" is quit loud but
do not be alarmed, it will not damage the cover)
Replace the batteries is indicated by the
symbols at the bottom of the battery-
compartment.
In order to save the time- and date-settings the
batteries have to be exchanged within 30 sec.,
the memory of the gauge is not affected by the
change of batteries.
