Battery insertion and removal Three useful tips: • The positive (+) side of the battery is always the smooth side. You can recognize the negative (-) side by the colored ring. • Always keep spare batteries with you. • If you think you cannot change the battery by yourself, ask someone to help you: a family member, friend or your hearing instrument specialist.
Low battery indicator Your hearing system may be programmed to inform you when the battery should be replaced for best system perfor- mance. You may hear an intermittent series of beeps and/or experience low amplification power or volume. Change the battery when either of these occurs.
Caution: Keep batteries and instruments away from the reach of small children. Batteries can be harmful if swallowed. If swallowed, consult a physician or a hospital immedia- tely. Change the batteries when any of the following occur: - Volume becomes softer or weak. - You hear a battery signal beep.
Battery compartment door lock Your instrument is equipped with a battery compartment door lock to prevent the unintentional removal of the batteries. To lock the battery compartment, open the compartment door to the first stop. Push the slide to the right with a suitable tool.
Inserting and removing your CENTRA BTE Make sure that your hearing instrument is turned off. Hold the earmold between your thumb and index finger and insert it carefully into your ear canal. You may find it helpful to pull your ear slightly upward or to the back.
Turning your CENTRA BTE ON and OFF Via the battery compartment Your CENTRA hearing system turns on automatically when a battery is inserted and the compartment door is completely closed. To turn OFF Press the battery compartment in the rear down to the first stop to turn the hearing instrument OFF.
Via the push button To turn your hearing instrument OFF, press and hold the pro- gram button for approximately 2 seconds. To turn your hearing instrument ON again, press and hold the program button for approximately 2 seconds. Please note that when you turn your hearing instrument OFF using the program button, you must wait approximately 10 seconds for the instrument to reset before you can turn it back ON again using the program button.
e2e wireless for CENTRA hearing systems Unique to your CENTRA hearing system is the e2e (ear-to-ear) wireless technology. This wireless functionality..automatically adjusts both of your hearing instru- ments simultaneously to different listening situations..allows use of accessories including the ePocket (bi-directional remote control) function.
During the use of the wireless link while the instrument is operated in telephone coil mode, pulsing noise may be heard due to pick-up of the transmission signal by the hearing aid telephone coil. Please use remote control in telephone coil mode only with a distance greater than 10 cm.
Using the program button button of your hearing aid or by attaching an audio shoe. Each time you press the program button, your hearing sys- tem switches to the next program, confirming each change with a beep. The number of beeps you hear coincides with the selected program: one beep for the first program, two beeps for the second program etc.
Telephone coil: When you hold a telephone receiver to your CENTRA hearing instrument, the telephone program Auto- Phone is automatically activated by the magnetic field of the receiver. Ask your hearing instrument specialist about these functio- nalities and he will program your CENTRA hearing system to your individual needs.
Using the directional microphone system Your CENTRA hearing system has a directional microphone system, which can be programmed to your individual needs. It can be set to an automatic mode so the CENTRA hearing system automatically adjusts the microphone system from omni-directional to directional mode and back, depending on the hearing situation.
Using the volume control Rotate the wheel upwards to increase volume. Rotate it down to decrease volume. For manual adjustment, rotate the wheel-shaped volume control with your index finger to select the desired listening volume (up for louder, down for softer). If your hearing system is equipped with a warning tone for volume control limits, once it is heard, adjusting the volume control further in that direction will have no effect.
Audio input Your hearing system is equipped with audio input capability. This enables the connection between the hearing system and accessories such as an FM system, tape recorder, television-, or an infrared device. It can be useful for adults in difficult lis- tening situations and for children in classrooms.
Before the audio shoe can be attached to the hearing system, the following steps have to be fulfilled: 1. Open the battery compartment. 2. Open the audio shoe cover. 3. Close the battery compartment. Attaching the audio shoe Removing the audio shoe With the audio shoe attached, the battery compartment switch is disabled and the hearing system can only be switched off with the push button.
Using the telephone telephone receiver away from the hearing instrument, it will automatically return to the previously used hearing program. You can also select the telephone program manually by using the program button. The telephone program can be set to microphone mode or telephone coil mode.
Note: Magnets can pose risks to electronics and magnetic storage mediums when placed in close proximity. Take care not to set magnets near computers, color monitors, television sets, floppy discs, credit cards, video/audio tapes, and other elec- tronic equipment. Keep magnets away from the reach of children. If swallowed, consult your physician.
Maintenance and care Your new CENTRA hearing system is a highly sensitive system. Proper care and handling will ensure the best possible performance. Earwax may accumulate on your earmold. If not cleaned regu- larly you can damage the hearing system or cause health pro- blems.
Important notes • Never expose your hearing system to extreme temperatures or high humidity. Do not store it in direct sunlight. Do not wear it when taking a shower or when applying hairspray. • As with all electrical, non gas-encapsulated systems, the hearing system must not be operated in explosion- endangered rooms.
