Figure 6: Normal Operating Screen on Graphic User Interface
3.7.1 Watch Dog Indicator (Spinning Arrow)
The spinning arrow represents the watch dog timer within the CPU of the unit.
NOTE: The arrow should be continuously spinning at all times. If the arrow is not spinning, the transmitter
will need to be rebooted to operate properly.
3.7.2 Command Confirmation
Each time the user operates a control on the transmitter, a message will be displayed on the graphic user
interface screen confirming what is being operated.
For example, if the second paddle is moved to its 4th position in the UP direction the display will show
‘MTN2 D1 SP=4’. This translates to ‘Motion 2, Direction 1, Speed 4’.
3.7.3 Battery Life Indicator
Remaining battery life is displayed in the bottom left hand corner of the graphic user interface screen.
Battery life is displayed in 5% increments.
NOTE: If using a different battery pack than what the unit originally shipped with, the battery life indicator
will be inaccurate unless the dip switch settings are set to the correct battery type being used. See
Section 3.1.2 for details to properly set the dip switches.
NOTE: The battery display is only shown when the battery is powering the device. When the device is
powered through the optional tethered connection the battery indicator is not displayed and a plug icon is
display instead.
NOTE: The battery life indictor will only show accurate battery life when using Magnetek approved battery
packs.
3.7.4 Signal Strength Indicator
The Signal Strength Indicator shows the radio signal strength at the receiver.
The Signal Strength Indicator is only available in systems equipped for Two-Way feedback (systems
utilizing the 433 MHz frequency band do not have Two-Way feedback available). For such systems,
Signal Strength is displayed at the bottom of the graphic user interface screen.
Signal Strength is displayed in 5% increments.

NOTE: On 433 MHz systems, the signal strength indicator will show minimum signal strength regardless
of the actual signal strength (systems utilizing the 433 MHz frequency band do not have Two-Way
feedback).
3.7.5 Two-Way Feedback System
This option allows the user to view various parameters that may be important to the operation of the
equipment on the graphic user interface display screen.
Parameters such as engine RPM, the torque or speed of a drive, temperature, current, or any other useful
values can be sent from the receiver and displayed on the transmitter.
NOTE: Systems utilizing the 433 MHz frequency band do NOT have Two-Way feedback available.
3.8 JOYSTICKS AND PADDLES/LEVERS
To activate the desired motor functions, operate the Joystick or Paddle/Lever that corresponds to the
desired motion.
To activate higher speed functions for those transmitter models so equipped, operate the Joystick or
Paddle/Lever further to activate the desired speed.
3.9 ROTARY SELECTOR SWITCH
The rotary selector switch can be used to select various modes of operation.
A rotary switch can have 2 to 12 positions to select from.
3.10 AUXILIARY SWITCHES
