CARING FOR YOUR TRANSMITTER The transmitter is a valuable object and should be treated with care. Here are some things you can do to prolong the life of your device:...
Page 24
CAUTION • Turn off your transmitter when it is not in use. Remove the battery if the device will not be used for several days. • When the transmitter is not in use, keep it in its case in a dry location out of reach of children and pets.
WARNINGS WARNING The transmitter and batteries can be dangerous if swal lowed or used improperly. Swallowing or improper use can result in severe injury or even fatalities. In case of ingestion, contact a physician immediately and the 24 Hour National Button Battery Ingestion Hotline at (202) 625-3333.
Page 26
• Risk of explosion if battery is replaced by an incorrect type or recharged. Dispose of used batteries according to the instructions. • The device is made of modern non-allergenic materials. Nonetheless, in rare cases skin irritation may occur. If you notice skin irritation in or around your ear or ear canal, contact your hearing care professional.
Page 27
WARNING • Please note that when using the transmitter, you must allow regular ventilation of the ear. If the ear is not adequately ventilated, there may be a slightly increased risk of infection or disease in the ear canal. We therefore recommend that you remove the device and ear-set from your ear when you go to bed, to allow the ear canal to be ventilated.
Page 28
• Do not use the transmitter in mines or other areas with explosive gases. • Do not wear your transmitter during radiation, X-rays, MRIs, CT or other medical treatments and scans. The emissions from these procedures as well as from other types of radiation, such as that in a microwave oven, can damage your device.
Page 29
WARNING Interference with active Implants • In order to show caution, we advise to follow the guidelines recom- mended by manufacturers of defibrillators and pacemakers regard- ing use of cell phones: • If you wear an active implantable device keep the Wireless Hearing Aids and Hearing Aid Accessories such as wireless remote controls or communicators at least 15 cm/6 inches away from the implant.
Page 30
CAUTION • Your transmitter has been tested for interference according to international standards. Nevertheless, it is possible that unforeseen interference may occur in the device due to electromagnetic radia- tion from other products such as alarm systems, room surveillance equipment and cell phones. •...
ADVICE NOTE • In most cases, using the transmitter infrequently will not permit you to gain full benefit from it. • The use of the transmitter is only part of hearing habilitation and may need to be supplemented by auditory training and instruction in lipreading.

(Benefits) The use of wireless transmission allows convenient and syn- chronized control of hearing aid functions. The DREAM wireless hearing aids share input information between the two partner hearing aids. In so doing, the wearers would experience the following additional user bene- fits (only when wearing binaural DREAM hearing aids).
Page 36
Coordination of compression – The DREAM hearing aids maintain the intensity level difference between ears (inter-aural level difference, ILD). In some situations where speech is presented to one side and noise the other side, this coordinated action could enhance the relative loudness of the speech sounds to the noise background and improve speech under- standing for some wearers.
