Pushbuttons

Items 6-13 describe how to use the pushbuttons. These
buttons are used (in conjunction with rotary switch) to
select operating modes and set power-on options. When a
button is pushed the beeper sounds (unless the beeper
has been turned off or the Data Output mode has been
selected). A summary of pushbutton operations is shown
in Figure 1. An annunciator is displayed to indicate that a
mode or option has been selected. A quick way to reset all
the pushbuttons to their default state is to turn the rotary
switch to an adjacent function and then back to the
function you are using.
