and press the ENTER key again. This removes
the padlock icon from the left side of the line.

Record to a Portable USB Drive
If there is a portable USB Drive inserted in the scan
tool’s USB port, the Record function saves data files
(that occur after pressing the Record key) to the USB
drive. You can then view (playback) the data files on
a personal computer (PC) that has the ConnecTech
software installed.
NOTE:
The length or number of files you can record
depends on the free space available on the USB drive.
To check USB drive free space, insert the drive into a USB
port on the PC and double-click the My Computer icon on
the Windows desktop. Right click the name of the USB
drive in the PC and click Properties on the menu that
appears. Alternatively, if you double-click the name of the
USB drive, you can view the drive contents and delete files
from the drive. For more information, refer to the Windows
User Guides and Help Systems.
To record to a USB drive, follow these steps:
1
Turn the scan tool off.
2
Insert the USB drive extension cable into the USB port
on the top of the scan tool and insert the USB drive
into the loose end of the extension cable.
NOTE:
With a DLC cable connected to the scan
tool, the USB drive will not fit into the USB port
unless you use the extension cable.
3
Follow the steps in
Record to Scan Tool Memory
on
page 40
to begin recording.
4
Notice the following items that are different when
recording to a USB drive instead of scan tool memory:
•
When pressed, the
Record
function key
changes to a
Stop
function key. Recording
continues until the USB drive is full or until you
press the
Stop
function key.
•
The screen status line displays the number of
frames being recorded, starting at the time you
press the
Record
function key.
•
After you press the
Stop
function key, the
status line displays a “Storing Data - Please
Wait” message. Do not do anything with the
scan tool or USB drive until this message is
gone.
•
To view the saved data files, use the Connec-
Tech program on the PC. For details, refer to
the ConnecTech Quick Start Guide, pdf User
Guide, and online Help System.
IMPORTANT: Do not remove the USB Drive with the
scan tool on; exit the application, turn the scan tool
off, and then remove the drive.
