Bit 10 (backlight color) is effective when using an NT30.
The PC status control bits remain unchanged if the NT30/30C status is changed
with the screen attributes or memory switches, which means that the statuses of
the PT status control bits do not match the actual status of the NT30/30C. For
example, the buzzer may sound even though the setting for continuous buzzer
bit 13 is OFF.
In this kind of case, control the NT30/30C by using the PT status control bits.
S Screen Display (Bit 15)
The screen display bit is used to display and clear the screen to prevent burn-in
on the CRT. Set bit 15 to 0 (OFF) to clear the screen. The backlight will also go
OFF at the same time.
When the screen has been cleared, the last displayed screen can be redis-
played either by turning bit 15 ON, or by pressing a touch switch. The backlight
will also light at the same time.
S Instead of turning bit 15 ON, a screen can be displayed by specifying its screen
number. For details on screen switching, see Switching the Screen Display
(page 197).
S If the screen is cleared and bit 15 is ON, turn bit 15 OFF and then back ON
again.
S Continuous Buzzer (Bit 13), Short Intermittent Buzzer (Bit 12) and Long
Intermittent Buzzer (Bit 9)
The continuous buzzer sounds continuously without interruption.
The short intermittent buzzer sounds for 0.5 seconds at 0.5 second intervals.
The long intermittent buzzer sounds for 1.0 seconds at 1.0 second intervals.
If 1 (ON) is specified for more than one of the three buzzers at the same time,
the buzzers will sound in accordance with the following order of priority:
Set bits 4 to 0 to 0 (OFF).
