Place earbuds in ears of the listener. When the M Listening Check is
attached, the sound processor immediately enters listening check mode.
You will be listening to the input sound source of the start-up program.
If you would like to listen to the other sound source configurations, use
the program button to cycle through the programs or begin wireless
streaming from the wireless device.
If you select a T-coil program, make sure you are synced to either a loop
or Roger myLink. If you begin wireless streaming from a wireless device,
be cautious and turn volume down on that wireless device. If listening
to a Roger transmitter or the PartnerMic, provide input to the Roger
transmitter or PartnerMic to assess audio quality.
Once listening check is complete, disconnect the M Listening Check
from the M Battery.
Remove the sound processor from the M Listening Check. Reconnect
the M Battery to sound processor and select desired settings for use.
