Potentially Explosive Atmospheres 
Turn off your ruggedized notebook prior to entering any area with a potentially explosive 
atmosphere. 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.  
The areas with potentially explosive atmospheres referred to above include fuelling 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. Areas with 
potentially explosive atmospheres are often but not always posted.  
Blasting Caps and Areas 
To avoid possible interference with blasting operations, turn off your ruggedized 
notebook when you are near electrical blasting caps, in a blasting area, or in areas posted: 
"Turn off two-way radio". Obey all signs and instructions. 
Operational Cautions 
Antennas 
Do not use the integrated radios of any ruggedized notebook that has a damaged antenna. 
If a damaged antenna comes into contact with your skin, a minor burn can result. 
Batteries 
All batteries can cause property damage and/or bodily injury such as burns if conductive 
materials such as jewelry, keys, or beaded chains touch 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.
