Refer to
Figure 1
for the following steps.
1. Using one signal harness, connect the AUX
output (usually CH. 3 or CH. 4) of the
receiver to the AUX input (Fig. 1, #1) of the
Dig Unit.
2. Using the other signal harness, connect the
Throttle output (CH. 2) of the receiver to the
Throttle input (Fig. 1, #2) of the Dig Unit.
3. Connect the signal harness from the rear
ESC to the rear output (Fig. 1, #3) of the
Dig Unit.
4. Connect the signal harness from the front
ESC to the front output (Fig. 2, #4) of the
Dig Unit.
5. Connect the LED harnesses to the LED
indicator plugs (Fig. 1, #5 & #6) of the
Dig Unit. Referring to Figure 1, the blue
LED corresponds to #5 and the red LED
corresponds to #6.
1. Use double-sided tape or tie-wraps to
secure the Dig Unit to a safe location near
the vehicle’s receiver, making sure that the
One-Touch Set-Up button is easily accessible.
2. Use tie-wraps to secure the blue and red
indicator LEDs to an easily visible location in
the vehicle.
3. Double check that the Dig Unit is located in
a place that will not pinch or damage the
wires or harnesses.
1. Locate the AUX channel on the transmitter.
2. With some transmitters, the AUX channel must
be adjusted. If your transmitter offers AUX
adjustments, the following is recommended:
a) Set HIGH ATV or EPA settings to the
maximum setting.
b) Set LOW ATV or EPA settings to the
maximum setting.
c) Make sure the AUX trim setting is set to
zero or the middle setting.
1. Turn on the transmitter’s power.
2. Before turning on your vehicle’s electronics,
make sure that your transmitter’s throttle
position and the AUX switch or dial are both in
the
NEUTRAL
position.
3.
PRESS and HOLD
the Dig Unit’s One-Touch button.
4. Turn on the power to the ESC.
5.
CONTINUE TO HOLD
the Dig’s One-Touch
button
UNTIL THE RED LED TURNS ON,
releasing the button
AS SOON AS THE
LED TURNS RED
.
6. Move the AUX switch or dial to one end
position, and hold it there until the green
status LED
TURNS SOLID GREEN
.
7. Move the AUX switch or dial to the
opposite end position, and hold it there
until the green status LED
BLINKS GREEN
.
When the green light stops blinking, the Dig
Unit is programmed.
8. Return the AUX switch or dial to
NEUTRAL
.
It is recommended to disconnect the red wire
from one of the ESC signal harnesses and use the
switches for both the front and rear ESCs.
A three-position switch or dial control is required to
operate the Dig Unit. A two-position switch will not work.

This one-of-a-kind unit requires two brushless or brushed systems and a three-channel transmitter to
operate. Refer to the Novak Web site
(www.teamnovak.com)
for a list of compatible systems and transmitters.
To benefit from all of the technical features of The Dig,
PLEASE READ ALL INSTRUCTIONS BEFORE OPERATION
Before programming Novak’s One-Touch Setup
for the Dig Unit, both front and rear ESCs need to
be set up either simultaneously or individually. Be
sure to follow manufacturer’s set-up procedures
for the ESCs carefully.
Please follow the steps below to ensure that your Dig
Unit is adjusted properly.
1. Turn on the transmitter and both speed controls power.
2. When the AUX switch is in the neutral position,
the blue and red indicator LEDs should be
illuminated, as well as the red LED and green LED
on board the Dig Unit.
a) Apply a small amount of throttle to confirm
that both front and rear speed controls are
functioning properly.
3. Position the AUX switch to the left or the right to
illuminate the red front indicator LED (Fig.1, #6).
This position should also illuminate the red LED
on board the Dig Unit. These should be the only
lights illuminated on the Dig Unit.
a) Apply a small amount of throttle to confirm
that
ONLY
the front ESC is operating.
b) Under normal operation, this is the “Front
Dig” function. This will allow the front motor
to spin (dig), while the rear motor locks into
neutral position (hill brake).
4. Position the AUX switch to the opposite direction
than the previous step. The blue rear indicator
LED (Fig. 1, #5) should be illuminated, as well
as the green LED on board the Dig Unit. These
should be the only lights illuminated on the
Dig Unit.
a) Apply a small amount of throttle to confirm
that
ONLY
the rear ESC is operating.
b) Under normal operation, this is the “Rear Dig”
function. This will allow the rear motor to spin
(dig), while the front motor locks into neutral
position (hill brake).
