Storage precautions

Do not store the device anywhere it may be exposed to water or in conditions of high humidity.

When the device is not in use for an extended period of time, bring it indoors and store it in some location with a temperature range of -20°to +70°C (-40°to 140°F) .

Cleaning the NAV 350

Use a damp soft dry cloth to wipe the device’s casing (not the display screen). Never use organic solvents such as benzene or paint thinner to clean the device. Use of these solvents can cause deformation or discoloration.

Use a soft, clean, lint-free cloth to clean the display screen. Moistened LCD screen wipes could also be used as required.

Troubleshooting the NAV 350

Recalibrating the screen

If while using the device, you discover tapping an item doesn’t bring up the appropriate response, it means your device has lost its calibration. Recalibrate the screen.
