4.2.4. KEYPAD FUNCTIONS.
(Refer to Figure 1.) Six
keys have dual functions, depending on whether the
power supply is in command entry status (waiting for a
command to be entered), or data entry status (waiting for
a number to be entered). Command entry status is
indicted on the LCD by a blinking colon and data entry
status is indicated by a blinking equal sign .

command and a number. The command label is
referred to when the unit is in command entry
status; the number is referred to when the unit is
in data entry status.
