NOTE
When POWER pushbutton is pressed to ON, TI automatically
performs a self-test sequence. Upon successful completion of
self-test, TI will be in normal operating mode.
b. Press POWER pushbutton to ON and allow at least 20 minutes for equipment warm-up.
NOTE
If TI crt displays DIAGNOSTIC, PUSH A/B TRIG TO EXIT
at power on, one of the power-up tests has failed. If the error
message on the bottom line of the display is TEST 04 FAIL xx
where xx is 01, 02, 10, or 11, stored calibration data is in error.
If this error message is displayed, press A/B TRIG pushbutton
to exit diagnostic mode and perform SECTION IV. If any
other error message occurs, the failure is probably not related
to calibration. In this case, the instrument should be repaired
before attempting calibration.

(1) VERTICAL MODE CH 1 and CH 2 on.
(2) VERTICAL MODE CH 3 and CH 4 off.
