Polycom recommends that standard acceptance procedures be followed prior to operating 
this equipment in proximity of life-support systems. 
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. 
Avoid areas with potentially explosive atmospheres include 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 marked with signs, but not always. 
Electromagnetic Interference and Compatibility
Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately 
shielded, designed, or otherwise configured for electromagnetic compatibility. 
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your handset in any facility 
where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment 
that is sensitive to external radio frequency (RF) energy. 
Pacemakers
The Health Industry Manufacturers Association recommends that you maintain a minimum separation 
of 6 inches (15 cm) between a handheld, wireless-radio product and a pacemaker. These 
recommendations are consistent with the independent research by, and recommendations of, Wireless 
Technology Research. Persons with pacemakers should: 
• ALWAYS keep the handset more than 6 inches (15 cm) from their pacemaker when the
handset is turned on
• Not carry the handset in a breast pocket
