normal operating mode and manual mode. Do not go to configure or calibrate mode.<br />

Hardware Configuration Lock<br />
Additional security is achieved using the hardware configuration-lock jumper<br />
shown in Figure 21 on page 34. When set to secure position, shorting the<br />
two-pin header, configuration and calibration are not permitted by the local<br />
interface or by remote communications. Pushbuttons, ValVue 2.4 and<br />
HHC 375 are locked out, except to examine configuration, calibration, and<br />
position. This is similar to Security Level 1 shown in the Pushbutton Lock<br />
Security Level table.<br />
