ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to 
electronic circuits. Vaisala products are adequately protected against 
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 with a wrist strap and a resistive connection cord to the 
equipment chassis before touching the boards. When neither of the 
above is possible, at least 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.
WARNING
Use only batteries of the same type as originally installed on the 
system.
CAUTION
Do not make changes to the wiring. Incorrect wiring can damage the 
device and prevent it from operating correctly.
CAUTION
Risk of damage to the equipment if the battery is replaced with an 
incorrect type.
