Power, Contrast, and Backlight Screen
To obtain the Power, Contrast, and Backlight (PCB) screen, shown to the left, touch
the Power / Contrast / Backlight button from the Preferences Menu. Each option is
explained in the following paragraphs.
Power
Turning off the backlight can lengthen the touchpanel battery life when the
touchpanel is inactive. Two buttons, Off and Standby, located in the left column of
the PCB screen are available to conserve power. The Off button completely shuts
down the touchpanel so that no power is drawn from the ST-BTPN, ST-DSN, or
external AC power pack. The Standby button shuts down the touchpanel display so
that minimal power is drawn from the ST-BTPN, ST-DSN, or external AC power
pack. These buttons have special software identities (reserve join numbers) and can
be recreated and programmed onto any page in the project. To reactivate the
touchpanel after the Off or Standby buttons have been utilized, simply press the
touchscreen.
Contrast
Screen contrast may need to be altered because of ambient light conditions, viewing
angle, panel temperature, or personal preference. One of the two contrast buttons
located centrally in the PCB screen may be held down for continuous and smooth
adjustment of the screen.
Backlight
Screen brightness may need to be altered because of ambient light conditions or
personal preference. Three brightness buttons, Low, Medium, and High, located in
the right column of the PCB screen may be selected to assign the backlight setting.
NOTE: Display backlight requires warm-up time to reach full brightness.
Touch RETURN, after parameters have been set, to return to the Preferences Menu.

Power Management

To obtain the Timeout screen, shown to the left of this paragraph, touch the Power
Management button from the Preferences And Settings screen. Turning off the
backlight when the touchpanel is inactive can lengthen the life of the touchpanel
battery (ST-BTPN). The length of touchpanel inactivity can be specified to minimize
power utilization.
Standby Timeout is displayed in the top left corner of the Timeout screen. This
setting turns the display and backlight off when the touchpanel is inactive for the
specified time. When the touchpanel is activated, the last screen to be displayed
reappears. The specified time is displayed in minutes. A two-minute Standby
Timeout is shown in the illustration. Minutes can vary from 0 to 120, where 0
disables the timeout. Down and up arrow buttons decrease and increase the timeout,
respectively.
Power Down Timeout is displayed in the top right corner of the Timeout screen.
This setting turns off all power when the touchpanel is inactive for the specified
time. When the touchpanel is activated, the first page of the project appears or the
last screen to be displayed reappears. Selection depends on how you setup your
custom program. (Refer to "Power Up On Last Page" on page 11 for details.) The
specified time is displayed in minutes. A 10-minute Power Down Timeout is shown
in the illustration. Minutes can vary from 0 to 120, where 0 disables the timeout.
