C550 menu structure
1 Display brightness
1 = Dim (ideal for night time driving)
2 = Medium
3 = Bright (ideal for daytime driving)
2 Dark mode
Dark mode switches off the display until there is an alert. One discreet LED will remain
illuminated so you know the C550 is operating correctly.
During an alert, the display will function as normal. If you press any button when Dark mode
is on, the display will function as normal so you make the necessary adjustments. The
display will switch off again after a few seconds.
3 Whisper mode
Whisper mode keeps the audio muted when you are under the speed limit. If you go above
the speed limit during an alert, normal audio will resume until you slow down again.
Whisper mode will include your speed tolerance setting. For example, if you have a speed
tolerance setting of 10%, Whisper mode will be active until you are going 10% above the
speed limit during an alert.
Note: If the speed limit at a stored location is not known, Whisper mode will not function and
the alert will be heard as normal.
4 Custom alert distances
Custom alert distances allow you to individually adjust the warning distance for each type
of alert. If you don’t want to receive warnings for any particular type of alert, you can set the
Custom alert distance to OFF.
