Important:

1. The accuracy of a weather forecast, when only using

pressure trends, is approximately 70 to 75 percent.

2. The weather forecast symbols may not reflect current

weather condition. The symbols are forecasting the
future.

3. A ‘SUNNY’ forecast covering the nighttime reflects fine

clear weather.

MAINTENANCE

When handled properly, this unit is engineered to give you years
of satisfactory service.

Here are several product-care suggestions:

1. Do not immerse the unit in water. If the unit comes in contact

with a liquid, dry it immediately with a soft lint-free cloth.

2. Do not clean the unit with abrasive or corrosive materials.

Abrasive cleaning agents may scratch the plastic parts and
corrode the electronic circuit.

3. Do not subject the unit to excessive force, shock, dust,

temperature, or humidity. Such treatment may result in
malfunction, a shorter electronic life span, damaged batteries,
or distorted parts.

4. Do not tamper with the unit’s internal components. Doing so

will terminate the unit’s warranty and may cause damage.
The unit contains no user-serviceable parts.

5. Only use new batteries as specified in this instruction manual.

Do not mix new and old batteries as the old batteries may
leak.

6. Read this instruction manual thoroughly before operating the

unit.
