Operation Manual of Cochlear Implant
Wearers of cochlear implant are open to electromagnetic interference of some equipments. But
this is a temporary phenomenon, and will not damage the cochlear implant or wearers' ear.
Interfering equipments generally include:
1) Around high-voltage line system;
2) Radio signal or TV signal transmitting tower;
3) Mobile-phone signal transmitting tower;
4) Safety system of shopping center or airport.
If you continuously hear humming sound or changing tones, please take down the speech
processor and contact our after-sale service personnel.

Electromagnetic Interference
Electrostatic discharge could damage implant's electronic components or speech processor's
programs. Static electricity is very common in our daily life. Following precautionary measures
may reduce electrostatic interference.
4.1 Children's playground with plastic toys
(such as slide, crawling tunnel, colored ball pool, small air inflated castle)
Before children enter a playground, please turn off and remove their speech processor, because the
off condition will still result in static electricity and program loss.
4.2 Electrostatic experiments
Before running electrostatic experiments, please take down speech processor.
4.3 Clothes
Friction of clothes will incur static electricity. All-cotton clothes are recommended. Generally,
wearers shall wear clothes first and turn on speech processor. Before taking off clothes, please turn
off speech processor and take it down, so as to prevent accumulation of static electricity.
4.4 Getting off a car
To get off a car, wearers shall grab car door, step on ground and then lose hold of hands. Children
shall get off in the same way with the help of parents or guardians.
4.5 Touching speech processor
When touching or taking up a speech processor, electric charge built-up in human body may be

Electrostatic Protection
Wearers shall pay attention to following aspects when taking part in sports or games:
2.1 Activities without physical contact (such as tennis, golf, badminton,
jogging and cricket)
Before taking these activities, please put the connection wire of battery case inside clothes, lest it
would be hooked and the speech processor be pulled off.
2.2 Strenuous activities and those with physical contacts (such as soccer,
basketball, squash and boxing)
Wearers of cochlear implant shall try not to take part in such activities. If they have to take such
activities, please remove speech processor beforehand for safety considerations. These activities
may bump or squeeze your head. Therefore, please put on a helmet or take other protective
measures to avoid direct impingement on head part with the implant.
2.3 Water sports (such as swimming, playing at waterside and diving)
Please remove speech processor first before taking water sports. Protective devices such as
goggles shall not pressurize on the head part with implant, lest damage of the implant occurs. If
possible, please wear a safety helmet to prevent any damage to implant.
Some wearers of the cochlear implant will suffer from loss of equilibrium sense. When they are
diving under water, they may lose the direction-sense and space-sense. Therefore, wearers of the
implant are suggested diving under the direction of professionals to distinguish directions. It is
risky to dive. Please be aware that water pressure and diving equipments may damage your
implant.
02
Sports and Games
some discomfort and pain at the implant site may still be experienced. Please consult with your
physician if this is an issue.
Monopole electro surgical apparatus is strictly prohibited.
The influence of thermal healing process, nerve stimulation, electric shock, ionizing radiation,
cobalt therapy, positive electron section scan, transcranial ultrasound, linear acceleration,
high-energy electric field and defibrillator upon implant are unknown, and these treatment
methods are not suggested temporarily.
