Crunch 2140S [28/31] Troubleshooting

Pulse Protection

Pulse (or instant-on) radar is more difficult to detect than conventional radar

because it remains “off” until activated to measure the speed of a targeted

vehicle.

When a pulse type transmission is detected, your CRUNCH detector sounds an

urgent audio warning and flashes the Alert strength indicators at their fastest

rate.

CARE AND MAINTENANCE

Your CRUNCH is an example of superior design and craftsmanship.

The following suggestions will help you to handle your detector in a proper way

so you can enjoy it for years.

Never leave the detector on the windshield or dashboard when you park your

vehicle. The temperature in the vehicle in summer can reach levels above what

is considered to be safe for this detector.

To make you less susceptible to break-in and theft, remove the detector from

your windshield or dashboard when you leave your vehicle.

Do not expose the detector to moisture. Rain dew, road splash, or other liquids

can damage the internal components and reduce sensitivity of the

detector.

TROUBLESHOOTING

If the detector does not turn on:

1. Check the power cord. Be sure all power connectors are properly

installed.

2. Check the fuse that controls power to the cigarette lighter socket. See

your vehicles owner's manual

3. The cigarette lighter socket might be dirty. Clean it with fine emery cloth

to ensure a good, clean connection.

4. Vehicle electrical problem exists.

5. Make sure that the volume control is in the ON position.

Caution: Do not place any metal object other than the cigarette lighter or a

cigarette lighter plug in the cigarette lighter socket.

If the detector gives a false alert when the vehicle hits or bumps:

1. Check the vehicle's electrical system, including main battery cable and

alternator connections.

2. Install a filter capacitor (470uF.25volts) on the back of the cigarette
