2. Warm-Up
Allow 30 seconds for display warm-up. At the end of this period,
the cursor will appear in the upper left corner of the display
screen. With the unit in Batch mode, you are able to type charac-
ters on the screen. (See figure 2for location of mode switch In
front panel.
)
a. If the RECEIVE and LOCAL pushbutton/indicators do not
light when the power switch is turned on, press the RESET
pushbutton. If either or both indicators still do not light,
check to see if the cooling fan inside the display unit is in
operation. This can be done by listening for the fan motor
or feeling air movement near the grill in the rear of the dis-
play.
b. If the fan is not operating, turn the power switch off and check
the fuses in the rear of the display (Figure 1). If afuse is
burned out, contact your Hazeltine Representative for are-
placement.
c. If the fan is operating and if after depressing RESET, the
RECEIVE and LOCAL pushbuttons arc not lit, turn the power
switch off and carefully recheck all cable connections. Fol-
lowing this, turn the power switch on again. If after depres-
sing RESET, the RECEIVE and LOCAL pushbutton/indicators
do not light, contact your Hazeltine Representative.
d. If the cursor does not appear after the display CRT has warmed
for areasonable period of time (no more than 3minutes), de-
press the HOME key. This will bring the cursor to the "home"
position in the upper left corner of the display. If the cursor
does not appear and if the entire screen is blank, it is
possible that the CONTRAST control is not adjusted properly
.
To make the adjustment, set the CONTRAST control com-
pletely clockwise. If the cursor still does not appear, turn
the power switch off and contact your Hazeltine Representative.
e. If the Hazeltine 2000 is used infrequently throughout the day,
It is recommended that power be left on rather than continu-
ously turning the unit off and on.
