9 Handling Condition

Be careful in handling or transporting products because excessive stress or mechanical

shock may damage products.

Warranty is void if device is opened.

10 Cleaning

See instructions in Installation Guide.

11 Operational Environment Conditions

Products are designed to work for electronic products under normal environmental

conditions (ambient temperature, humidity and pressure). Therefore, products have no

problems to be used under the similar conditions to the above-mentioned. However, if

products are used under the following circumstances, it may damage products and

leakage of electricity and abnormal temperature may occur.

‒ In an atmosphere containing corrosive gas (Cl2, NH3, SOx, NOx etc.).

‒ In an atmosphere containing combustible and volatile gases.

If there are possibilities for products to be used under the preceding clause, consult with

Murata before actual use.
