The user may return from any category to the selected meter display by pressing the buttons on
either Line 3 or Line 4.
5.16 Data Entry Rules
Numerical data will not take effect until the user has pressed the ENTER button. Arrow key

exceptions to these rules.
Numerical entries will indicate their present value until the user enters a new value.
Starting from the meter display on Lines 3 and 4, categories are accessible in the order specified
in Table 5-1, starting with RF Control. Press the MENU button to scroll through the available
categories. While in any menu category, press either the Line 3 or Line 4 buttons to return to the
selected meter displays. Appendix B describes each category in detail.
