3.7 RPM4-E-DWT Direct Function Keys
3.7.1 Summary
Note
Table 4 provides a brief summary of RPM4-E-DWT direct function key
operation. It may be useful to keep a copy of this summary near the
E-DWT-H, especially when first becoming acquainted with its operation.
Local operation of RPM4-E-DWT is through the front panel keypad. To minimize multi-
layered menu structures, the keypad numerical keys also provide direct access to the most
commonly used functions. The function accessed is labeled on the bottom half of the key.
Direct function keys are active whenever RPM4-E-DWT is in its MAIN RUN screen. Table 4
summarizes the operation of the direct function keys.
