3–12 2× Extender
Note
The 2× Optical Extender is compatible with all HM-Series camera
models and provides the user the ability to see farther and/or
enhance the resolution of objects in the field of view. The 2× Optical
Extender is mounted on the bayonet mount in front of the existing lens
on the camera.
To mount the 2× extender,
first remove the lens cover
assembly. Then, position the
2× extender so that the
release lever on the 2×
extender is in the 5 o’clock
position on the bayonet
mount. Firmly push the
extender onto the bayonet
mount, then rotate the lens
counter-clockwise so that the
release lever reaches the 3
o’clock position where it will hit a hard stop.
Note
To remove the 2× extender, press the release lever and rotate the
extender clockwise until the release lever is roughly at the 5 o’clock
position and pull straight off.
Caution!
The 2× Optical Extender is not waterproof and should not be used
in wet environments.
The 2× extender is manually focused by rotating the outer rubber-
coated ring.
Be sure to replace the lens cover assembly when the 2× Extender
is not in use to avoid moisture, dust, or other contaminants
reaching the inner lens surface of the 2× Extender.
