GLOSSARY OF TERMS
REFERENCE
Motor on Axle Mixing: Used to control either the Front and Rear throttles together or independently, giving you Dig and Burn
functions. These functions are mostly used in Rock Crawling.
MPH: Miles Per Hour.
Operating Voltage: The safe voltage that the transmitter or receiver can operate within. Exceeding the minimum operating
voltage can result in loss of power to the device(s). Exceeding the maximum operating voltage can result in damage to the
devices(s).
Output Power: The power (in Milliwatts) that your transmitter transmits a signal. Output power is defined by government
guidelines and differs by region.
Over Voltage Alarm: The Over Voltage Alarm will sound if the transmitter battery voltage is greater than 9.6 volts. To clear this
alarm, turn the transmitter OFF and replace the transmitter battery with one that when fully charged does not exceed 9.6 volts.
Parallel (Crab) Steering: Used with Four Wheel Steering, both front and rear wheels pivot right and left together.
Parallel Trim: A Trim technology that when selected, the servo End Points move in equal amounts as the Trim when you use
the Trim Switches. This results in balanced servo travel without the need to manually readjust the End Points.
Point Auxiliary: Used to program Auxiliary Channel 3 or Auxiliary Channel 4 to move the servo to up to 6 different points along
its travel, then cycle through those Points. For example, if your model requires a separate 3-position or more switch to operate
a feature, the Point Auxiliary function can be customized to control this.
Point Setting: Locates the actual point in the servo travel that you want a specific programming setting to occur. This setting
can vary depending on the actual programming setting the Point setting is controlling.
Power Switch: Turns the transmitter ON and OFF.
Push-Button Rotary Dial: The Push-Button Rotary Dial (also referred to as the Up Key, Down Key, or Enter key) is used along
with the BACK/CANCEL Key to facilitate transmitter programming. It allows you to quickly and easily navigate the various
Programming and System Menus and switch between the Top Screen and the Telemetry Screen.
Push-Button Switch: The transmitter features two separate Push-Button Switches in different locations (Sw1 and Sw2). Each
Push-Button Switch is programmable and will perform a different function depending on what function is assigned to it.
Receiver Battery Voltage Fail Safe: Used to set a custom voltage that the Receiver Battery Fail Safe function will Activate at.
When your receiver battery voltage drops to the programmed voltage, the throttle servo will move to the predetermined position
programmed using the Fail Safe function. If this occurs, recharge or replace your receiver batteries.
Receiver Voltage Display: Displays the current voltage of the receiver battery on the Telemetry Screen.
Release Setting: Determines how quickly the Brake moves from Neutral to the percentage value determined by the Stroke
setting when the Anti-Lock Braking function is Active.
RPM: Revolutions Per Minute.
RPM Display Monitor: Displays the current RPM on the Telemetry Screen from the RPM Sensor in graphical format.
Servo Monitor Display: Displays the output levels of the four different channels in bar graph form, allowing you to monitor servo
operation in a virtual manner.
Servo Reversing: Used to electronically switch the direction of servo travel. For example, if you move the steering wheel to the
right, and the steering servo moves to the left, you can use the Servo Reversing function to make the steering servo move to
the left.
Servo Speed: Used to slow down the transit speed of the servos. Servo transit speed can be slowed in both the Forward and
the Return to Center directions.
SHR Servo Operating Mode: Using this setting with Digital servos will increase the servo's response time, even above the
manufacturer's stated specification. Do not use with Analog servos!
SSR Servo Operating Mode: If you're using Airtronics SRG Digital servos, you can use the SSR setting for the fastest response
time. This results in the ultimate feel and response, making you feel more in control of your model than ever. Use only with
Airtronics SRG Digital servos!
Steering Program Indicator: Indicates on the LCD Screen up to four different programming options that are currently
programmed to the Steering channel. The Steering Program Indicator will only be displayed if a Steering channel Programming
Value is programmed.
Steering Trim Display: Displays the current position of the Steering Trim Switch on the Top Screen.
Steering Wheel: Proportionally operates the model's right and left steering control. The Steering Wheel features a foam grip for
increased comfort, control and feel. In addition, the Steering Wheel spring tension and travel limits can be adjusted.
Steering Wheel Tension Adjustment Screw: Used to adjust the spring tension of the steering wheel to best suit the feel of the user.
Step Auxiliary: Allows you to program the Auxiliary 1 servo or Auxiliary 2 servo to move a defined amount when toggled ON
and OFF using a Push-Button Switch.
