1.2 WARNINGS AND PRECAUTIONS

Operating Manualwww.ushio.com 5
Fitting Style: The adapter nut allows the UDC3 to attach to the user’s borescope.
Rotate the nut clockwise to attach the UDC3 to a borescope and counterclockwise
to remove. The standard configuration of the Ushio UDC3 is with an adapter nut
that threads onto the standard universal light guide post’s Storz/ACMI adapter
thread or by thumb screw for Olympus style ferrule.
WARNING!
Upon power up, the UDC3 drives the LED to high output intensity.
Avoid looking directly at the LED during initial turn ON or anytime
while unit is ON.
Light Intensity Buttons:
Momentary pressing button or holding
down the button next to this symbol
decreases the intensity of the light.
Momentary pressing button or holding
down the button next to this symbol

2.3 PRODUCT ORDERING INFORMATION

Midori™UDC3 www.ushio.com8
The UDC3 unit’s internal LED operates on 2 rechargeable Lithium-Ion batteries.
When new or fully charged batteries are installed, the battery capacity is ~80
minutes at full intensity and ~110 minutes at 75% intensity of continuous operation.
Battery Installation
1. At the bottom of the UDC3’s battery hatch door, rotate the locking knob
counterclockwise until the line on the knob is pointing 90° from the indentation
mark on the hatch. Remove the hatch. Refer to figure 2.
2. Insert the batteries into the unit using the battery symbol orientation as
a guide. The negative terminal of each battery should be in contact with the
spring on each circuit board, refer to figure 3. Attach the hatch door then rotate
the locking knob clockwise until the line on the knob is pointing toward the
indentation mark.
Note: For added safety,the battery hatch door may only be inserted into
the UDC3 body in one direction. If the door does not easily slide into
the case, rotate the hatch door 180°. This ensures the battery polarity
cannot be reversed.
To remove batteries, rotate the battery hatch door knob counterclockwise a quarter
turn until it stops, remove the door and allow the batteries to slide out.

When 2 batteries are charging at the same time, press
SLOT to select the charging slot (1) or (2). Then you
can view the individual charging information (ie. Battery
Type, Charging Status, Charging current, Charging
voltage & Charging time) for the selected charging slot.
To change charging speed: Default charging speed is
500mA, this can be increased to 1000mA for Li-ion,
IMR, and LiFeP04 batteries, to do that, simply press
[mode] button once. Digital screen will show the
updated charging current. (1000mA charging current is
NOT available for NIMH and NICO).
Note: 2A USB power source is needed to charge 2x Li-ion battery at
1000mA speed setting
Tip: It is safe to use 1A current option for Li-ion, IMR and LiFeP04
batteries as long as its capacity is higher than 1000mAh, for capacity
1000mAh or below, please stay with the default charging current
500ma for better battery life span.
Activate / Deactivate LiFeP04 charging mode: To
properly charge a LiFEpo4 battery (please check label
on battery to identify if it’s LiFeP04), LiFeP04 charging
mode will need to be manually activated.
To do that:
1. Press “slot” and “mode” button together.
2. Battery type screen will show [LiFeP04].
3. LiFeP04 charging mode is enabled
4. To get out of LiFeP04 charging mode, press 2 buttons together again.

The UDC3 unit is rated for water resistance. The UDC3 unit is rated for slight water
contact and mild detergent cleaning solutions only. However, it should NOT BE
IMMERSED in water or cleaning solutions for any prolonged periods of time. After
cleaning, remove UDC3 unit from cleaning solution, dry and store the device in a
clean and dry environment.
WARNING!
Failure to comply with the following may result in damage to the
UDC3 unit and will void the product warranty.
Use caution when cleaning the UDC3 unit; some methods may be harmful and
could result in extensive damage. Manual cleaning is the recommended method.
Certain cleaning agents may damage the device’s materials. Only use water with a
mild detergent such as a nonabrasive hand or dishwashing soap. Do not immerse
the UDC3 unit in an ultrasonic cleaner.
CAUTION!
Ensure that the battery hatch door is fully tightened on the O-ring
seal to prevent liquid intrusion into the battery compartment.
Never use any organic solvents to clean the UDC3 unit, other than
isopropyl alcohol.
CARE AND MAINTENANCE
SECTION 4
4.1 CLEANING THE UDC3 UNIT

Operating Manualwww.ushio.com 19
If the UDC3 unit comes in contact with liquid, rinse with isopropyl alcohol and then
dry with compressed air, commercial compressed gas canisters or dry damp cloth.
Note: Air dry is highly recommended to reduce contamination of the
optical components and reduce the possibility of oxidation of the
materials used in the construction of the UDC3 unit.
CAUTION!
Do not allow the UDC3 unit to remain in liquid cleaning solution for
prolonged period of time.
In addition, thoroughly dry the battery hatch door seal around the O-ring, with
compressed air or by thoroughly wiping any excess liquid from this area, prior to
removing the battery hatch door. This will prevent any trapped fluid from entering
the battery compartment and exposing the electronics to fluids.
CAUTION!
Ensure there is no trapped liquid between the battery hatch door
and body prior to removing the battery hatch door.
