MARC carts offer a safety beeping option, which is heard while MARC is moving in autonomous mode. This
beeping, similar in sound to a traditional forklift, is a double-beep active while in motion to warn workers
nearby that the cart is in motion. Note the volume is increased and decreased using the volume buttons
that control the audible system notifications and both are adjusted together. Warning beeps can be
enabled or disabled using the single button, and current status is displayed on the button as shown to left.
To turn the beeping on, press and hold the button for 3 seconds till you hear the double-beep tone. The
icon will turn green to indicate is has been activated. To turn of the beeping, press and hold the button for
more than 6 seconds until the triple-beep sound is heard. The icon will turn grey to indicate beeping has
been turned off.
The volume (+) button increases the volume in increments of 10%, and the volume (–) button decreases
volume in increments of 10%. When in the main screen showing the programmed location buttons, tap the
battery level button on the lower right to access the second screen with the volume adjustment buttons.
Powered Assist manual drive buttons allow the user to operate the cart manually. The buttons will move
the cart in the direction shown when pressed. Use caution, as during manual movements the safety
features of the cart are disabled
. When in the main screen showing the programmed station buttons, tap
the battery level button on the lower right to access the second screen with the manual drive buttons. For

the cart, but the issue should be addressed as soon as possible. For more information, see Troubleshooting
on page 37 . Press the battery level indicator button to return to the main screen.
