Introduction This guide is intended for Hearing Care Professionals. It provides important information on hearing instruments with permanently built‑in power cells (lithium‑ion batteries). CAUTION It is important to read this guide, the user guide and the safety manual thoroughly. Follow the safety information to avoid damage or injury.
B efore and after fitting You have to prepare the hearing instruments before you can start fitting. A ssembling A power cell is installed in every hearing instrument on delivery. There is no need to insert a battery. Attach the suitable receiver unit and a suitable ear piece to the hearing instruments. The procedure is the same as for any other of our RIC hearing instruments.
Charging The hearing instruments are pre-charged on delivery. They should have sufficient power for a first fitting session. We recommend to fully charge the hearing instruments before first fitting and handover to the client. A full charging cycle takes approximately 4 hours. Follow the operating conditions in both the hearing instrument's and the charger's user guide. C onnecting You can either fit the hearing instruments wirelessly with ConnexxLink or use the CS44 connection beneath the push button: Use the included tool to lift the push button. Do not use sharp tools. Plug the CS44 cable as shown in the picture.
N oting the serial number You can find the hearing instrument's serial number beneath the push button, next to the CS44 connection. D isconnecting Depending on the charging status, the hearing instruments may switch off after being disconnected from the programming device. This safety feature avoids deep‑discharge of the power cell. To turn the hearing instruments back on: Put them into the powered charger for a moment. After removal from the charger the hearing instruments are automatically turned on. Or press the push button for several seconds.
Replacing the housing NOTICE This maintenance task must be performed by the Hearing Care Professional. Disassembling Remove the receiver unit and the axles. Insert the included tool into the front end of the hearing instrument and detach the bottom housing. You may feel some resistance since the hearing instrument sits firmly in the bottom housing.
