palm.  Hold the battery wires with two fingers up and away from the battery.  This will prevent water from entering the connectors.

Swing your arm in a hard, downward motion with an abrupt stop, 10 times to remove any excess water from the battery.  It is important to get as much water out of the battery as possible.  Excess water in the battery increases the chance of the battery overheating, which shortens its lifespan, and could lead to an unsuccessful flight.

Hold the battery by the tape around the battery wires and place the battery in the battery bag.  Continue holding the tape on the wires, and grab the sides of the battery (outside the bag).  Hold the battery horizontal with the "TOP" label facing away from you.  Turn the battery completely around in a counter-clockwise direction (towards you) 4 times.  A good, tight braid should be formed in the wires.  Wrap the wires under and around the battery lengthwise.  

Stuff the battery into the battery compartment on the radiosonde.  It will be a tight fit.  The “TOP” label should be facing up.

Take the wires on the sonde and twist the black wire (big connector) around the red wire in a clockwise direction 4 times; again, a tight braid should be formed.  Connect the wires on the sonde to the battery.  CONNECT THE BLACK WIRE FIRST.

Stuff the wires inside the battery compartment between the battery and the outside of the sonde.  Again, it will be a tight fit.  It is important to get the wires fully inside the compartment.  Now that the battery is connected, ALLOW A MINIMUM OF 5 MINUTES FOR THE BATTERY TO WARM-UP.  

Tape the battery compartment flap shut with the two remaining pieces of tape that you saved earlier.  If necessary, regular tape can be added if the tape supplied with the sonde is not long enough.  Take the sonde to the RRS workstation and prepare the software.  This can be done while the battery is powering up.  When transporting the sonde, it is recommended that you carry it by the plastic ring.

Further detailed instructions on radiosonde preparation can be found in NWSM 10-1401, Appendix N.
