Dim/Dark Modes

Dim/Dark Mode reduces illumination of the display.
• Briefly press and release the Dark button to reduce
illumination to a Dim setting.
• Briefly press and release the Dark button a second
time to engage Dark Mode. In Dark Mode, the
display appears a bit dimmer than Dim mode and
will go completely dark for as long as a signal is
being detected and for 20 seconds after, then the
display returns to the dimmer illumination. Dim
Modes can be engaged during an alert.
• Briefly press and release the Dark button a third
time to restore full illumination to the display.
