Preparing RS41 Unwinder
To start using the RS41 unwinder, first detach the unwinder stick
(number 1 in
Figure 6 on page 22 ) from the unwinder body. The stick is
attached between two plastic clips in the unwinder hook (number 2).
Detach the stick from between the plastic clips and pull it out from the
unwinder bottom plate (3).
If the unwinder stick is tightly attached to the bottom plate, it is a good
idea to slightly twist the unwinder stick before pulling it out. When you
pull the unwinder stick out, make sure that the string unwinds and that
it is not tangled. Also make sure that the string does not unwind too
much. See
Figure 7 on page 23 for a suggestion of how to keep the string
from unwinding too much.
In the unwinder body, the unwinder string runs under a round plastic
clip (4) on the bottom plate. This will keep the string attached to the
unwinder, and the radiosonde attached to the balloon.

To prevent the string from getting tangled in the clip, make sure the
round plastic clip (number 4) is level with the unwinder bottom plate. If
the lip is bent, bend it gently back to level position but be careful not the
bend it above the bottom plate.
