Beeper Volume – The “Volume” Parameter
2.8.6.2 Beeper Volume – The “Volume” Parameter
Important: When you adjust the volume using this parameter, the change is
saved to memory.
To access the “Volume” parameter:
• In the “Parameters” menu, position the cursor on the “System” option, and
press <F1>.
• Position the cursor on the “Volume” parameter, and enter a value from 0 to
15. The higher the value, the louder the volume.
• Press <F4> to save the change.
2.9 The Display
Terminals with liquid crystal displays (LCDs) are equipped with backlighting to
improve character visibility in low light conditions. The 7035 and 8260 terminals
have LCDs as a standard feature. The 8260 is also available with an
electroluminescent (EL) display. The 8255 can be ordered with a vacuum
fluorescent display (VFD) or a LCD. If the ambient light is low, the backlight will
turn on after a key is pressed, after a scanner decode, or after data is received from
the host. The backlight will remain on for a configurable duration. Refer to
“Backlight” on page 125 for details about specifying how long the backlight will
remain on.
2.9.1 Adjusting The Display Contrast
Note: Contrast can only be adjusted on terminals with liquid crystal displays.
There are two ways to adjust the contrast – by pressing the <BLUE> key in
combination with <F1> and <F2> or by assigning a contrast value at the
“Contrast” parameter.
