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.
