ON/OFF key – Press once to turn the TDR on. This will restore all the
previous settings from the last time it was turned off. Press once to turn the TDR
off.
Soft Reset
Step 1. With the TDR off, press and hold the ENTER key.
Step 2. Press the ON/OFF key for 1 second and release.
Step 3. After 2 seconds release the ENTER key.
Note: If the TDR’s menu cursors stop responding, the measurement screen
does not show correctly, or any other failures to perform correctly occur, the
TDR’s firmware may need to be reset. The Soft Reset (similar to rebooting a PC)
function performs several housekeeping functions and restores the TDR to
factory default values. It will NOT erase saved traces or changes to the Cable
List. The low battery icon’s operation is not affected. It will still appear and blink
to warn about a low battery condition. See figure 1-3.
