3.2.1.4 KEYPAD FUNCTIONS
Keypad functions are listed in Table 3-2. 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 indicated by a blink-
ing colon
(:_:_:)
and data entry status is indicated by a blinking equal sign
(=_=_=)
.
NOTE: Keys with dual functions are labeled with both a command and a number. The com-
mand label is referred to when the unit is in
(:_:_:)
command entry status; the num-
ber is referred to when the unit is in
(=_=_=)
data entry status.
