5.4 FACTORy DEFAULT RECOVERy
If the boards configuration gets into an unknown setting, it can be restored
to the factory default configuration with one of the following procedures.
Use the CAL:DEFAULT command to re initialize the settings. If that does
not work, use the hardware default jumper.
1. Power the board off.
2. Locate the default jumper and place a shorting jumper on it. See
Section 2.11 for jumper locations.
3. Power the board on. After 5 seconds the LEDs should blink as the
variables are reset. Wait until the LEDs stabilize and the board has
finished its save procedure (takes approximately 10 seconds).
4. Remove the shorting jumper and operate the unit normally.
