Humidity Indicator
==================

HUNTER's interior is kept dry by an internal store of silica gel
desiccant, kept in a muslin bag. The dryness of HUNTER's interior is
essential to its correct operation, and is indicated by a humidity
indicator in the corner of the display window.

The colour of the indicator should be checked at intervals.

.. Warning::

   THE HUMIDITY INDICATOR MUST ALWAYS BE BLUE

If it takes on a pinkish colour, the unit must be returned to HUSKY
Computers promptly to avoid corrosion of internal parts. If the colour
changes immediately after an accident involving water or high humidity,
a fault has occurred in the sealing, and there could be water inside the
unit.

If you suspect that water has entered the interior, you **MUST** take
the following action:

#. Remove the battery
#. Return HUNTER to HUSKY Computers, or authorised agents.
