The touchpanel battery life can be lengthened by turning off the backlight 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-BTP, ST-DS, or
external AC power pack. The Standby button shuts down the touchpanel display so
that minimal power is drawn from the ST-BTP, ST-DS, 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. Consult your dealer. To
reactivate the touchpanel after the Off or Standby buttons have been utilized, simply
press the touchscreen.

personal preference. Three brightness buttons, Low, Medium, and High, located in
