Product Related Safety Precautions

The Humidity and Temperature Transmitter HMT100 delivered to you

has been tested for safety and approved as shipped from the factory. Note

the following precautions:

CAUTION Do not modify the unit. Improper modification can damage the product

or lead to malfunction.

ESD Protection

Electrostatic Discharge (ESD) can cause immediate or latent damage to

electronic circuits. Vaisala products are adequately protected against

User's Guide ______________________________________________________________________

8 ___________________________________________________________________ M210701EN-D

ESD for their intended use. However, it is possible to damage the product

by delivering electrostatic discharges when touching, removing, or

inserting any objects inside the equipment housing.

To make sure you are not delivering high static voltages yourself:

- Handle ESD sensitive components on a properly grounded and

protected ESD workbench. When this is not possible, ground yourself

to the equipment chassis before touching the boards. Ground yourself

with a wrist strap and a resistive connection cord. When neither of the

above is possible, touch a conductive part of the equipment chassis

with your other hand before touching the boards.

- Always hold the boards by the edges and avoid touching the

component contacts.

Recycling

Recycle all applicable material.

Dispose of batteries and the unit according to statutory regulations. Do

not dispose of with regular household refuse.
