2.4 Wireless safety 
Wireless routers incorporate a wireless radio module. Ensure the antenna is positioned at 
least one metre away from you and other people in normal operation. 
If in a hospital or health care facility, do not use the router in areas where guidelines to 
switch off mobile phones are posted. Medical equipment may be sensitive to RF energy. 
The operation of cardiac pacemakers, other implanted medical equipment and hearing 
aids can be affected by interference from wireless routers when placed close to the 
device. People with pacemakers are advised to keep the wireless router away from the 
pacemaker while it is on. 
Do not operate your wireless router in the presence of flammable gases, fumes or 
potentially explosive atmospheres. Wireless routers should not be used anywhere that 
blasting operations are taking place. 
Wireless routers operate using radio signals and cellular networks cannot be guaranteed 
to connect in all possible conditions. Therefore, you should not rely solely on any 
wireless device for life-critical communications.
