CAUTION:
The MDW 9040 handset is a radio transceiver device. It is recommended that 
the handset not be placed within 6 inches of a pacemaker.
It is recommended that standard acceptance test procedures be followed prior to 
operating this equipment in proximity of life-support equipment. Until more is 
known, the FDA suggests that people with pacemakers may want to take some simple 
precautions when using or carrying digital wireless telephones. They should ensure 
that there is ample distance between the digital wireless telephone and the 
pacemaker—by not placing the phone next to the pacemaker implant (for example, in 
a shirt or a coat pocket directly over the pacemaker implant) when the phone is on and 
ready to receive a call and by holding it to the ear opposite the side of the body where 
the pacemaker is implanted when using the phone. They should consult their 
physicians or medical device manufacturers to determine if additional precautions are 
necessary.
Hearing Aid 
Compatibility
Most electronic equipment, such as equipment in hospitals, is shielded from RF 
energy. RF energy from wireless telephones, however, may affect some electronic 
equipment.
Although the TransTalk wireless telephone is compatible with inductively coupled 
hearing aids, a physician or hearing aid manufacturer should be consulted to 
determine if a hearing aid is adequately shielded from external RF energy. The 
operation of inadequately shielded medical devices may be adversely affected when a 
portable wireless telephone is operating in close proximity. Use of an optional 
headset would solve this problem.
