Battery Chemistry Switch
This switch allows the ESC to detect voltage. When the
switch is in the OFF position, low voltage cutoff (LVC)
is disabled. You will know you have reached LVC when
the motor power decreases while the boat is in operation.
li-po: move the battery chemistry
switch to the ON position
Ni-MH: move the battery chemistry
switch to the OFF position.
Tip: The ESC programming card
(DYNM3821, sold separately) allows the consumer to
adjust low voltage cutoff and other ESC programming.
At the factory, the ESC is programmed at High Cutoff.
High Cutoff: The Ni-MH cutoff voltage is .9 volts per
cell and the Li-Po cutoff is 3.3 volts per cell. High Cutoff
allows ample power in reserve after cutoff for returning
the boat to shore.
low Cutoff: The Ni-MH cutoff voltage is .7 volts per
cell and the Li-Po cutoff is 3.0 volts per cell. Low Cutoff
allows longer run times, but leaves less power in reserve
after cutoff for returning the boat to shore.
Transmitter Battery Installation
This transmitter requires 4 AA
batteries.
1. Remove the battery cover from the
transmitter.

Antenna Tube Installation
1. Carefully feed the end of the longer receiver
antenna through the grommet inside the hull.
2. Pull the antenna wire out of the grommet
towards the outside of the boat, then slide the
antenna through the antenna tube.
3. Insert the tube into the grommet, then fit the
cap onto the tube.
4. Apply clear tape to the antenna, grommet
and hull in the boat to keep the antenna from
moving.
Arrange the shorter antenna in the hull at a right or near
90 degree angle to the antenna in the tube. Attach the
antenna inside the hull, away from all electrical wiring and
components, using clear tape.
The outer end of the antenna must be installed above the
waterline of the boat to get the best reception of your
transmitter's signal.
