Up to here, the [CLEAR] key can be used. Pressing [CLEAR] key
clears the selected number, and selection can be retried from the
beginning. If [ENTER] key is pressed, the diagnosis of only the
selected number is executed, and the result is displayed.

If any key is pressed while the result display is blinking, the screen
returns to the initial Test Mode Menu screen. Where visual check
is necessary such as a still picture check, or when an error oc-
curred, use [PREV] key for repeated checking. To go to the next
step, press [NEXT] key.

If the diagnosis of selected number does not exist, the initial screen
is restored when [ENTER] key is pressed.

6-2-2. All Items Check

Press any key other than numeric keys when Model No. is dis-
played to activate the all items check mode. In the all items check
mode, RAM check is simplified. In concrete, only the skipped
blocks such as 0-ff, 500-5ff, a00-aff, f00-fff, 1400-14ff, ... (ad-
dresses) are checked. Check is executed from the top item of the
diagnosis check items list sequentially. In a checking where visual
check is not necessary, check progresses to the next item auto-
matically unless an error occurs.
In case of an error or visual check is necessary, press [PREV] key,
and the item concerned is repeatedly checked. To go to the next
item, press [NEXT] key.
