Skip the description in the RDR 2000 manual on how to enter calibration mode. The MX20 allows a single
button push to enter calibration mode. The MX20 MUST be in Install mode to calibrate the radar head.
Follow the instructions below.
1. Turn the MX20 on.
2. After boot-up is complete, key-in the install sequence 1, 4, 6, on the menu keys.
3. Press the FN key until one of the options is RADAR. If the RADAR option is not available, see the
section on "Configuring Radar".
4. Press the "smart key" corresponding to the RADAR option. You will now switch to the Radar page.
5. Press the STBY key to put the radar unit into standby mode. This may take up to twenty seconds.
6. Once the MX2O is in standby mode, one of the menu options will be "Test". Press the TEST key.
7. Once the MX20 is in Test mode, press the ENTER key to switch to the "Setup" page.
8. On the "Setup" page, press the key labeled CALB to enter calibration mode. This will take a couple
of seconds.
9. The MX20 will flash all faults briefly to indicate calibration mode has been entered. If this fails, turn
power off and try again.
At this point, follow directions in the RDR 2000 Installation Manual starting with "400 Hz Ref Gain" section.
Selection of calibration parameters is done by adjusting the gain setting according to the values in the RDR
2000 Installation Manual. On the MX20, the "smart keys" labeled "Gain" are used to adjust the gain setting
and select the parameter to be calibrated. Follow the RDR 2000 Installation Manual instructions for
calibrating the selected parameters.
