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

HARNESS INSTRUCTIONS

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.

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.

It is recommended to disconnect the red wire

TRANSMITTER ADJUSTMENTS

1. Locate the AUX channel on the transmitter.

A three-position switch or dial control is required to operate the Dig Unit. A two-position switch will not work.

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.

from one of the ESC signal harnesses and use the switches for both the front and rear ESCs.

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.

MOUNTING THE DIG

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.

ONE-TOUCH PROGRAMMING

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.

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.

PROPER FUNCTION

Please follow the steps below to ensure that your Dig Unit is adjusted properly.

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).
