the DT770.

For more information, refer to the instructions that came with your projector or monitor.
Connecting the Tethered Pen
You must attach the pen to the DT770 by connecting the pen’s tether to the DT770’s connection
panel. This tether provides the power to the pen and the pen indicator.
1. Connect the pen’s tether to the Pen Tether port.
2. Thread the tether through the cable management clips on the underside of the DT770 to
ensure that the tether is tidy and appropriately positioned for when you use the pen.
NOTE: You can thread the pen’s tether towards the bottom or the side of the DT770.
CAUTION
Connect the DT770 to your computer using either the USB cable or the
RS-232 cable. Don’t connect both cables.
