Lamp and Battery Replacement
COVER REMOVAL AND REPLACEMENT
If the lamp or battery is to be replaced, it is necessary to first
remove the instrument cover:
1. Disconnect the charging transformer from AudioScope 3 and
turn the instrument “OFF” before beginning.
2. Insert a coin into the slot of the lock mechanism at the end of
the handle.
3. Turn the coin in either direction until the line under the word “OPEN”
on the lock is aligned with the recessed line on the housing.
4. Slide the cover back (away from the speculum end), until the
arrows on the instrument case align.
5. Lift the cover.
NOTE: Once the cover is removed, care should be taken not to
touch any of the internal components except as described in
this manual.
