NEC 110 - Manual (Page 5)

Potentially Explosive Atmospheres: Turn off your radio
product, prior to entering any area with a potentially explosive
atmosphere, unless it is a radio product type especially qualified for
use in such areas (for example, Factory Mutual Approved). Do not
remove, install, or charge batteries in such areas. Sparks in a
potentially explosive atmosphere can cause an explosion or fire
resulting in bodily injury or even death.
Batteries: All batteries can cause property damage and/or bodily
injury, such as burns if a conductive material such as jewelry, keys, or
beaded chains touches exposed terminals. The conductive material
may complete an electrical circuit (short circuit) and become quite hot.
Exercise care in handling any charged battery, particularly when
placing it inside a pocket, purse, or other container with metal objects.
Cleaning and Drying Considerations: Using a leather carry
case may help protect the surfaces and help prevent liquids (e.g., rain)
from entering into the interior of the radio product. This product is not
waterproof, and exposing the unit to liquids may result in permanent
damage to the unit.
If your Wireless Telephone interior gets wet, then do not try to
accelerate drying with the use of an oven or a dryer as this will
damage the Wireless Telephone and void the warranty. Instead, do
the following: 1. Immediately power off the Wireless Telephone. 2.
Remove Battery Pack from Wireless Telephone. 3. Shake excess liquid
from Wireless Telephone. 4. Place the Wireless Telephone and Battery
Pack in an area that is at room temperature and has good airflow. 5.
Let the Wireless Telephone and Battery Pack dry for 72 hours before
reconnecting the Battery Pack and/or powering on the Wireless
Telephone. If the Wireless Telephone does not work after following the
steps listed above, contact your dealer for servicing information.
CAUTION
The areas with potentially explosive atmospheres referred to
above include fueling areas such as below decks on boats, fuel or
chemical transfer or storage facilities, areas where the air contains
chemicals or particles, such as grain, dust or metal powders, and
any other area where you would normally be advised to turn off
your vehicle engine. Areas with potentially explosive atmospheres
are often but not always posted.
