Turning The System On - Radio Shack TRS-80 Preliminary User's Manual

TURNING THE SYSTEM ON

Turn on the Video Monitor by pressing the POWER button. Turn on
the TRS-80 Keyboard by pressing the POWER button on the back
(next to the POWER Jack); the red LED just to the right of the
Keyboard should light up and the screen should show READY.
Adjust C (contrast) and B (brightness) controls on the front of
the Monitor for the sharpest display. Set Brightness so the
background is gray and the words are white. Do not set Brightness
too high.
If Monitor does not show READY, press the Keyboard's POWER
switch off, wait 10 seconds, and then turn it on again.
(Pressing the power switch slowly can cause the machine to
"get confused". Turn it on with a quick push.)
Now type in P. . and hit ENTER. This is a test to see that the
m
Computer powered-up properly. The display should read:
P . M .
3533
If the number is not 3583, turn the Keyboard's POWER switch off,
wait 10 seconds, and then turn it on again. Repeat the test and
verify that the number is 3583.(It's good practice to perform this
simple test whenever you turn on the TRS-80. Always type
ENTER before performing the test.)
NOTE: There is a Reset button inside a door at the left
rear of the Keyboard assembly. This Reset button can be
used to unlock a looping program or if the TRS-80 does
not turn off a cassette or in other such abnormal program
situations.
