NOTE
When the system is first turned on from new, only the City or Highway icon will show on
the screen because the Show Compass and IntelliMute functions are set to off at the
factory. See pages 14 and 16 to turn these functions on.
NOTE
In some vehicles, power is supplied to the cigarette lighter even while the ignition is off.
If this is the case with your vehicle and you have turned the SmartPower off, you should
turn off or unplug your detector when parking for lengthy periods. Cobra recommends
leaving SmartPower at the factory setting, which is on. See page 18.
