Screen Lighter/Darker
You can change the contrast of the touchscreen whenever you
want. The PCWS saves your settings when you sign out.
Steps
1. Press [Contrast Up] or [Contrast Down] to adjust the screen
to your satisfaction.
Each keypress gradually lightens or darkens the touchscreen.
Notes
General
Information
You can sign in to a PCWS, change the contrast of the screen, perform necessary
transactions, and sign out. When you sign out, the contrast setting is saved in
memory. The next time you sign in at this PCWS, the touchscreen contrast adjusts
automatically.
Contrast settings are saved for each UWS; they are not global. You must set the
contrast you prefer for each PCWS you use.
If you haven’t set a preference, the PCWS uses the contrast settings of the current
screen.
Example
When Samantha signs in at PCWS, she notices the overhead light is causing a glare
on the touchscreen. She presses [Contrast Down] until she can see the screen
clearly, posts an order, and signs out. When she signs in at PCWS 10 minutes later,
the screen adjusts automatically to the contrast setting she entered previously.
