Safety and General Information - 7
facilities that may be using equipment that is sensitive to external 
RF energy.
Aircraft
When instructed to do so, turn off your phone when on board an 
aircraft. Any use of a phone must be in accordance with applicable 
regulations per airline crew instructions.
Medical Devices
Pacemakers
Pacemaker manufacturers recommend that a minimum separation 
of 6 inches (15 centimetres) be maintained between a handheld 
wireless phone and a pacemaker.
Persons with pacemakers should:
• ALWAYS keep the phone more than 6 inches (15 centimetres) 
from your pacemaker when the phone is turned ON.
• NOT carry the phone in the breast pocket.
• Use the ear opposite the pacemaker to minimise the potential 
for interference.
• Turn OFF the phone immediately if you have any reason to 
suspect that interference is taking place.
Hearing Aids
Some digital wireless phones may interfere with some hearing aids. 
In the event of such interference, you may want to consult your 
hearing aid manufacturer to discuss alternatives.
Other Medical Devices
If you use any other personal medical device, consult the 
manufacturer of your device to determine if it is adequately 
shielded from RF energy. Your GP may be able to assist you in 
obtaining this information.
