A size 10 hearing device battery is used. Remove the stick tab from the battery after the battery door is
fully opened. Close the battery door smoothly to turn on the device. Do not close the battery door with
force as it may damage the hearing device.
If you cannot close the battery door, check whether the battery is installed correctly. The flat or positive "+"
battery side should be facing up to where the tiny "+" or red/blue mark is on the battery door. Remove
the battery if the hearing device is not to be used for an extended period time.
