Handset Operational Warnings
Certain operational environments are potentially hazardous. Please read the following text
carefully to ensure that you understand the handset’s operating conditions.
Potentially Explosive Atmospheres
Do not take your handset into 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.
Warning:
Avoid areas with potentially explosive atmospheres including fueling areas such as
lower 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 market with signs, but not always.

Your handset is powered by a removable battery that you will need to fully charge before
first using the handset and then recharge periodically.
Caution: Battery and charger compatibility
Only use batteries and chargers compatible with your handset. For more information, see
