Volume control and mute Volume control Micro Mic is designed to provide a comfortable listening level from the moment it is activated. However, for some devices or listening environments you may want to adjust the volume. This can be accomplished in a variety of ways. Keep in mind that volume adjustments apply to the streamed signal only. • Use the “+” and “-“ buttons (see page 9) to adjust volume to a comfortable level.
i Note: The Micro Mic will revert to its default level when restarted. The Resound Unite™ Remote Control (optional accessory) can also be used to adjust the streaming volume in the hearing instrument. Please ask your hearing care professional for more information about this accessory. Mute The signal from the Micro Mic can be muted, should the wearer of the device want to engage in conversations or activities irrelevant for the hearing instrument user.
Mute Light indicator Configuration/Blinking pattern Mute Light indicator Normal Operation (Unmuted) Normal Operation (Muted) Special features Drop detection In the event that the Micro Mic falls from a height of more than 75 cm (30 inches), a built-in sensor will mute the output streamed to the hearing instruments for up to 2 seconds. This is done to protect the hearing instrument user from very loud and unpleasant impact noise should the unit be accidentally dropped during use.
How to lock the volume control • Make sure the Micro Mic is turned OFF. • Press and hold the volume ‘-‘ button and the Power ON button for 1.5 seconds until the status LED turns green (Micro Mic powering up) and release the Power button. • Keep pressing the volume ‘-‘ button until a green-orange-red LED sequence is shown on the status LED after 10 seconds. The status LED will now blink twice every 2 seconds to indicate that the volume control is locked.
Test mode The Test mode is primarily intended to be used for pediatric transparency measurements. The transparency measurement evaluates if the hearing instrument and wireless (remote) microphones provide equal outputs when presented with the same 65 dB SPL input stimulus. When in Test mode the microphone is set to omnidirectional mode with 0 dB gain when placed horizontally in the test chamber. Please refer to relevant guidelines for performing transparency measurements.
• To exit Test mode and save settings turn off the Micro Mic and lock the volume control (see Volume control lock section in the Special features chapter). i Note: Adjustments to reach transparency can be made on the Micro Mic and/or in the hearing instrument using the fitting software. 400545000-GB-15.10-Rev.A.
