Whistler XTR-280 - Manual (Page 3)

Mounting Guidelines
• Mount the unit as low as possible near the
center of the windshield.
• Do not mount your unit behind wipers,
ornaments, mirrored sunscreens, etc. These
obstructions have metal surfaces which can
affect radar and laser signals and reduce
critical warning time. (Regular tinted glass
does not affect reception.)
• Some windshields have an Instaclear ™ or
Electriclear ™ type coating, which affect radar
signals. Consult your dealer or the owner’s
manual supplied with your vehicle to determine
if your windshield has this coating.
• Avoid placing unit in direct contact with wind
shield.
• To reduce the possibility of theft, conceal your
unit when not in use.
Windshield Mounting
• Install the two suction cups and rubber bumper
onto the bracket by fitting them into their holes.
• Press the suction cups onto the windshield at the
location you have chosen.
INSTALLATION
• Slide the detector onto the bracket until it locks into
place.
• If necessary, the unit may be leveled by bending the
windshield bracket.

unit’s power jack.
• Plug the large end into the vehicle’s cigarette lighter.

Battery Charging
External/Home Battery Charger - The home
battery charger (optional with the 1788R) pro-
vides approximately 10 hour recharge time for
Ni-MH batteries. Simply observe the battery
polarity when installing the batteries into the
charger and plug the home charger into a con-
venient outlet.
Internal/Power Cord - While traveling, plug
your included power cord into your detector
and into your lighter socket to slowly charge the
rechargeable batteries. This will also provide
power to the detector. The display will show an
asterisk, i.e., when the unit is
charging the batteries. The asterisk will flash
during charging and go out when charging is
complete.* N
