Changing batteries
The correct battery size appears in the “Instrument View” in the
first section of this document.
A worn out battery should be removed immediately and
disposed of according to local regulations.
You will hear 2 beeps when it is time to change the battery. This
pre-warning will be repeated in moderate intervals until the battery
runs out. The battery may run out shortly after a pre-warning or
within the next couple of hours depending on battery capabili-
ties and individual hearing losses.
If the battery runs out, the instrument turns off. When that
happens, 4 beeps are played to indicate that the instrument is
no longer operating.
Replace the battery.

To replace the battery, follow these instructions:
• Open the battery door completely by pushing the raised edge on the bottom of the
instrument. To assist with the handling of the batteries, the magnet at the end of the
MultiTool can be used to help you.
• Remove the sticky label from the + side of the new battery.
• The new battery may be inserted by using the magnetic end of the MultiTool.
Ensure that the positive (+) marking faces the positive (+) sign printed on the battery
door. Close the battery door.
If any moisture is on the battery surface, it should be
wiped off before use. When you change the battery,
it will take a few seconds before the battery works.
To assist the handling of the batteries, the magnet
placed at the end of the tool can be used.
