Precautions for use
Pacemakers
Pacemaker manufacturers warn that the distance between the voice box and the
pacemaker of the heart must be at least 6 inches (15.3 cm), otherwise the voice box
can interfere with pacemakers.
People with pacemakers should consider the following:
●
Always keep a distance (at least 6 inches) between the voice and pacemaker
when the voice box is on.
●
Do not carry your voice box near your chest.
●
Use the voice box in the ear that is furthest from the pacemaker.
Please turn off your voice box if you feel there is interference, and consult your doctor
as soon as possible.
Emergency calls
Like any voice box, this voice box works with radio signals that can not guarantee
connection in all conditions. Therefore, you should never rely solely on a voice box
for essential communications like medical emergencies. To make or receive calls, the
voice box must be switched on and in a service area with adequate signal strength.
To make an emergency call, enter the local emergency number in standby mode and
press the call button.
