Issues to remember
Know your serial numbers.
Note the Colour and Size of the cables for easy
reference.
Use the Dry Aid Kit every night.
Minimize the chances that the cables are pulled/ stretched.
Careful with that ear hook.

Issues to remember
Avoid sand/ dirt
Clean with slightly damp cloth
Keep dry + use dry pack provided
Avoid sources of ESD Plastic slides, Balloons
Computer/ TV screens
Avoid medical treatments inducing currents Diathermy or neurostimulation
Electroconvulsive Therapy
Monopolar electrosurgical instruments must NOTbe used on the head or neck of a CIuser. Use
Bipolar electrosurgical instruments instead. Do not use Ionizing Radiation therapy directly over
