Using this method, the backlight status (lit/flashing) can be controlled at any re-
quired time.
The PT status control area must be allocated to a word in the host, accordingly,
no special settings are required for the control of buzzer.
The bit for controlling the PT status (PT status control bit) is provided at the fourth
word (n + 3 words) from the beginning of the PT status control area.
To control the backlight status during the operation of the PT, operate the PT sta-
tus control area as indicated below.
Set 0 (OFF) or 1 (ON) for bit 8 in the fourth word (n + 3 words) from the beginning
of the PT status control area.
• To turn the backlight on: 0 (OFF) 1 (ON)
• To flash the backlight:
By turning off the screen while it is not in use, the backlight lasts for a long time
and, at the same time, afterimage on the display panel can be prevented. The
backlight is turned off automatically when the screen is turned off. If the screen
saver function is set to Display, however, it is not possible to prolong the life of the
backlight since it is not turned off when the screen is turned off.
The PT provides the following two methods for turning off the screen.
