Juniper Systems Allegro Desiccant Kit - Manual

Why Install a Desiccant Pack into the Allegro?
The Allegro is waterproof when the battery and PC card doors are
properly closed. However, the unit is built with a micro-pore filter
in the wall of the Allegro, which allows for a balance of atmospheric
pressure between the inside and outside of the case. This can allow
the passage of atmospheric gases, comprised mostly of nitrogen and
oxygen as well as the minor elements such as carbon dioxide and
water vapor.
In higher humidity environments, water vapor may collect inside
the case to a level sufficient to cause condensation inside the case
when the Allegro is subjected to colder conditions. This condition
appears as fog inside of the touchscreen covering the display. Placing
a desiccant pack in the Allegro case can reduce the possibility of
condensation on the inside of the touchscreen.
Included Items
When you order a desiccant pack, you
receive two desiccant packs in a small, air-
tight, resealable plastic bag. Each desiccant
pack is shipped with two small pieces of
Velcro. The first piece is attached to the
desiccant pack, and the other is attached to
the first piece of Velcro.
