How to Restore the Default Password
Warning
To avoid electrical shock or personal injury, remove the test leads and
any input signal before removing the back case from the UUT.
If the calibration password is forgotten, the default password () can be restored with
these steps:
1. Turn the rotary switch from OFF to B.
2. Remove the back case from the UUT.
3. Remove the shield and leave the PCA in the top case.
4. Apply 6.0 V across the battery pads (XBT1) + and – on the back of the PCA. See
Figure 10.
4. Short across the  keypad on the back of the PCA. See Figure 10. The UUT should
beep (if the beeper is enabled). The default password is now restored.
5. Remove the 6.0 V supply and install the shield and back case on the UUT.
