Ω , and “MY CABLE” cable type. This indicate a successful Soft Reset. This
action will perform firmware housekeeping and reset the TDR to factory default settings. To see
more about when to use the Soft Reset refer to the ENTER key instructions or consult the
Operating Manual.
Note: If the TDR’s menu cursors stop responding or the measurement screen does not open
correctly 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. However, the battery menu’s
remaining operating time will be reset. This will need 2-3 re-charges for the smart charger to
recalculate the battery’s operating time. 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.
