Product-Related Safety Precautions
WARNING

WARNING
CAUTION
CAUTION
Conduct soundings in a safe environment and in accordance with all
applicable restrictions and regulations.
Do not use the radiosonde in an area with power lines or other
obstructions overhead. Make sure that you check the area for such
obstructions before using the radiosonde.
Do not use the radiosonde without consultation and cooperation with
local and other applicable aviation authorities.
Do not modify the unit. Improper modification can damage the
product or lead to malfunction.
Do not use the radiosonde for any purpose other than for soundings.
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. It is possible to damage the product,
however, 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 an ESD workbench is not available, ground yourself to the
equipment chassis with a wrist strap and a resistive connection
cord.
VAISALA________________________________________________________________________ 9
User's Guide ______________________________________________________________________
- If you are unable to take either of the above precautions, touch a
conductive part of the equipment chassis with your other hand
before touching ESD sensitive components.
- Always hold component boards by the edges and avoid touching
the component contacts.
Lithium Battery-Related Precautions
CAUTION
Do not place the lithium battery in fire or apply heat to the battery.
Do not pierce the battery with nails, strike the battery with a hammer,
step on the battery, or otherwise damage the outer casing.
Do not subject the battery pack to strong impacts or shocks.
Do not expose the battery to water or salt water, or allow the battery to
get wet.
Do not disassemble or modify the battery. The battery contains safety
and protection devices which, if damaged, may cause the battery to
generate heat, rupture or ignite.
Do not leave the battery in direct sunlight, or use or store the battery
inside cars in hot weather. Doing so may cause the battery to generate
heat, rupture, or ignite. Using the battery in this manner may also result
in shortened life expectancy and loss of performance.
Never short circuit, reverse polarity, disassemble, damage, or heat the
battery over 100 ºC (212 ºF). If an exposed lithium battery does not
start on fire, it will burn even more violently if it comes into contact
with water or even moisture in the air.
DO NOT THROW WATER ON A BURNING BATTERY. A fire
extinguisher must be used.
