Electronic devices
Most modern electronic equipment is
shielded from RF energy.
However, certain electronic equipment
may not be shielded against the RF
signals from your device.
Pacemakers
The Health Industry Manufacturers
Association recommends that a
minimum separation of six (6”) inches
be maintained between a phone
and a pacemaker to avoid potential
interference with the pacemaker.
These recommendations are consistent
with the independent research by
and recommendations of Wireless
Technology Research.
If you have a pacemaker:
• Always keep your ZenFone 4 more
than six inches (15cm) from your
pacemaker when turned on.
• Do not carry your ZenFone 4 in your
breast pocket.
• Use the ear opposite the pacemaker
to minimize the potential for
interference.
• If you have any reason to suspect
that interference is taking place,
switch off your ZenFone 4
immediately.
Hearing aids
Some digital phones may interfere
with some hearing aids. In the event of
such interference, call ASUS Customer
Service to discuss alternatives.
