If your system has the BASIC/ APL switch, it can execute either BASIC
or APL language statements. The language used is selected only
during the power up procedure or when the RESTART switch is
pressed. Make sure your system is plugged in and turn the power on.
If the power is already on, press RESTART and wait a few seconds.
During this time, the system performs internal checks to make sure it
is operating correctly. Do
not
press any keys while these internal
checks are being made. If you inadvertently press a key, you must
press RESTART to continue.
If an error is detected during these checks, the PROCESS CHECK
indicator may come on. If the PROCESS CHECK indicator comes on,
press RESTART. The system will again perform the internal checks. If
the light comes on again, call for maintenance service.
The IN PROCESS indicator comes on whenever the display screen is
blank, which indicates that the system is doing internal processing.
ENTERING AND DISPLAYING DATA
Next, let's look at the display screen. Your display screen should look
like this:

If the READY message does not appear, press RESTART again, and
