Accessory socket cover Figure 1: CP810 Sound Processor parts Processing unit The processing unit, which is the brain of your processor, converts sound signals for transfer to your implant.
Getting to know your processor The processing unit allows you to perform the following functions: • Turn your processor on and off. • Change your program (e.g. from Everyday to Noise). • Turn the telecoil on and off. • Lock and unlock processor buttons. You can change microphone volume and sensitivity using the remote assistant. If your processor has an Advanced user interface, you can also change volume or sensitivity using the processing unit. For more information, see Advanced userinterface.
Getting to know your processor The Standard Battery Module consists of a battery holder and a battery cover. 1 2 3 Figure 4: Battery holder with zinc air batteries (1), tamper resistant battery cover (2) and battery lock (3) To prevent children from detaching the battery cover from the battery holder, you can use the Cochlear™ Nucleus® CP800 Series Tamper Resistant Battery Cover. You can also lock the standard battery module or the rechargeable battery module to the processing unit.
Getting to know your processor Coil magnet A magnet holds the coil in place over your implant. Figure 6: Coil magnet If your coil falls off often, or if you experience discomfort, you can change the depth of the magnet in the coil. You can also use a stronger or weaker magnet. For more information, see Adjusting and replacing the coil m agnet. Microphone protectors The processor microphones capture sound, which is processed by the processing unit for transfer to the implant.
Getting to know your processor Processor options Depending on your listening needs, your clinician can enable the following options on your processor: • SmartSound™ technologies to improve your hearing. SmartSound is a suite of four input sound processing technologies. These technologies are applied to four available programs: Everyday, Noise, Focus and Music. For more information on these programs, see Changing programs.

Wearing your processor Your processor is designed to fit neatly and comfortably behind your ear. You can also wear the processing unit behind the ear and attach the battery module to the body. This provides greater comfort and flexibility for both adults and children. You can change the processor coil cable, coil magnet and earhook for optimal comfort (e.g. if the coil cable length is too short, you can easily change the cable to a longer one).
Wearing your processor Attaching the coil and coil cable If the coil is not attached to the processing unit, or the coil cable is not attached to the coil, you need to attach them before placing the processor on your ear. Attaching the coil cable to the coil To attach the coil cable to the coil: 1. H old the coil in one hand 3. and the coil cable plug in the other hand as shown. 2. Align the coil end of the coil cable plug with the coil.
Wearing your processor The coil functions properly only when the coil cable is fully inserted into the processing unit. To check if the coil is receiving sound signals from the processor, you can use the in-built coil sensor on the remote assistant. For more information on how to use the coil sensor, see Checking the coil. If you attach the coil to the processing unit when your processor is turned on, your processor may turn off. If this occurs, turn your processor back on.
Wearing your processor Changing the earhook Earhooks are available in different sizes. If your earhook becomes loose, you should replace it. To change the earhook: 1. Hold your processor and the earhook as shown. 2. Rotate the earhook to pull it away from the processing unit. • 3. Hold the new earhook in one hand and your processor in the other hand as shown. 4. Attach the earhook by pushing the lower end of the earhook onto the processing unit. Avoid twisting the earhook as it may become loose.
Wearing your processor If adjusting the depth of the magnet is not sufficient, you can replace the magnet with a stronger or weaker magnet. Adjusting magnet depth To adjust magnet depth: 1. Place the thumb and index finger on the magnet as shown. 2. Turn the magnet in a clockwise direction to increase magnet strength, or in an anti-clockwise direction to reduce strength. Changing magnet strength To change the magnet to a stronger or weaker one: 1. Place the thumb on the top 2.
Wearing your processor 3. Hold the new magnet between the thumb and index finger as shown. 4. Hold the coil in the other hand. 6. Turn the magnet in a clockwise direction until it is in position. 5. Insert the magnet gently into the magnet slot on the topside of the coil. The side with the star should face upwards. The magnet fits easily. Do not overtighten the magnet, or force it to turn if it becomes difficult to turn during insertion or removal.
Wearing your processor To change the coil cable to a longer or shorter one, do the following: Remove the coil cable from the processing unit as shown. 1. Place the thumb and index 2. finger over the finger grips on the processor end of the coil cable plug as shown. Gently pull the coil cable plug away from the processor. You may damage the coil cable, coil cable plug or the processing unit if you pull on the cable, or twist the cable plug. Remove the coil cable from the coil as shown. 1.
Wearing your processor Attach the new coil cable to the coil as shown. 1. Hold the coil in one hand and the coil cable plug in the other hand as shown. 2. Align the coil end of the coil cable plug with the coil. 3. Push the coil cable plug firmly into the coil until it clicks into place. Using the Snugfit™ for a secure fit The Cochlear™ Nucleus® CP800 Series Snugfit™ helps hold the processing unit in place more securely than using the earhook alone.
Wearing your processor Attaching and removing the Snugfit To attach the Snugfit to the processor: 1. Hold your processor in one hand as shown. 2. Hold the Snugfit between the thumb and index finger of the other hand and gently squeeze on the wings. This helps fit the Snugfit more securely on the processor. 3. Gently slide the Snugfit upwards until the base of the Snugfit is aligned with the base of the processing unit.
Wearing your processor Changing the way you wear your processor The Cochlear Nucleus CP800 Series LiteWear option provides greater comfort and flexibility in the way children and adults wear the processor. It allows the battery module to be attached to the body. The processing unit is worn behind the ear and is connected to the battery module by the Cochlear™ Nucleus® CP800 Series LiteWear Cable. You cannot use the LiteWear cable with the Compact Rechargeable Battery Module.
Wearing your processor Locking and unlocking the tamper resistant battery cover To prevent children from removing the battery holder from the battery cover, you can lock the tamper resistant battery cover of the Standard Battery Module to the battery holder. To lock the tamper resistant battery cover: 1. Insert the battery holder into the battery cover as shown. 2. Using a screwdriver, gently rotate the lock in a clockwise direction until it is positioned horizontally.
