Add Batteries to Transmitter 

(See Fig. 2.5)

Remove the rectangular battery cover from the back of the Transmit-
ter. Insert 4 “AA” Alkaline batteries taking note of proper polarity of
positive and negative contacts (Negative end of the battery should make
contact with the “spring”).

Charge Lithium Polymer Rechargeable “Bahoma” Cell

gnets) connector (patent pending). The

Bahoma connector system uses strong plated magnets to hold the
battery onto the charger and onto the Micro9 Butterfly receiver. These
magnets are also used as electrical conductors. The terminals of the
Bahoma cell are protected from shorting to each other by a plastic
safety guard.  

(See Fig. 1)

On the front of the transmitter, slide the 3 position switch to the mid-
dle position to put the transmitter into it’s “Charge” mode. The LED
inside the charger door will be  blinking rapidly. Slide the hinged
clear polycarbonate plastic charger door downwards to unlock it, and
then lift it open. Attach the Bahoma cell to the corresponding magnet-
ic terminals. The Bahoma cell will “click” into place on the charger by
magnetic attraction and with good electrical contact.  The LED inside
the charger will now glow brightly.  Close the clear charger door, and
slide it up to shut it with a small click.  Your cell is now charging,
and when the bright LED goes out, the cell is fully charged and ready
for use.  Charge time is about 60 minutes typically. The charger of the
Butterfly Transmitter is set to charge at about 20mA.

Important Notes about Lithium Polymer Batteries

The lithium polymer rechargeable battery should not be used if it has
become swollen or has been physically damaged, crumpled, or cut.
Always use the supplied charger built into the transmitter. Always
charge the LP30 cell with the clear charger door closed. The supplied
lithium polymer cell can provide you with many discharge cycles
when used properly, but eventually it will require replacement.
Replacement cells are available from your dealer or from Plantraco
directly at www.plantraco.com. Always dispose of used or damaged
batteries appropriately

If you need to dispose of a damaged Lithium Polymer cell, you can
make a solution of about 2 cups of water and 1 cup of table salt in a
disposable container outdoors.  Put the damaged cell in this concen-
trated salt water solution and leave it outside overnight.  The damaged
cell may then be disposed of in the garbage safely.

Replacement cells are always available from your dealer or from the
plantraco website
