3. UDC3 Operation, Batteries and Charger
UDC3 Operation
The UDC3’s internal LED operates on 2 rechargeable Lithium-Ion batteries. When new or
fully charged batteries are installed, the battery capacity is ~60 minutes at full intensity and
~90 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.

Figure 4: Standard Universal Light Guide Post
1. Hold the UDC3 so that the main body fits comfortably in one hand, allowing easy
manipulation of the adapter nut with the thumb and forefinger.
2. Tighten the adapter nut onto the light guide post by turning rotary collar or thumb
screw clockwise. Do not turn the UDC3 body.

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.
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
increases the intensity of the light.
2. Adjust light intensity as needed, refer to figure 6.
3. After use, turn the UDC3 OFF by pressing the GREEN power button.
4. Remove the UDC3 from the borescope by rotating the adapter nut counterclockwise.
5. Remove batteries when UDC3 is not in use for extended periods of time.

WARNING!
USE ONLY APPROVED BATTERIES.
Use only pairs of fully charged batteries. Do not mix newly charged and
depleted batteries.
Never mix rechargeable battery with non-rechargeable batteries.
Do not incinerate, disassemble, overcharge or short circuit the battery.
Do not expose the battery to high temperatures above 122ºF/50ºC.
CAUTION!
The batteries should be removed from the UDC3 if it will not be used for
extended time.
Charging the Batteries
1. Plug the AC adapter into a wall outlet.
2. Connect the AC power adapter to the DC IN jack located at the top of the charger.
Make sure no battery is installed. The LED indicator will turn green when the charger
is ready.
3. Slide the battery into the charger, making sure the negative side of the battery is
inserted into the charger first against the spring contact. The LED indicator will turn
RED when the battery is charging.
4. LED indicator solid red light indicates batteries are charging and not ready for use.
5. LED indicator solid green light indicates installed batteries are fully charged and
ready for use.
6. When battery has been fully charged, pull the battery out of the charger and unplug
the AC adapter from the charger.

LED-alter Current: When the battery is fully charged, LED turns red to green,
and the current at that time called LED-alter Current
= 70 ±30mA × 2CH.
Charging Mode: Constant current and constant voltage charging
Short circuit current: When a short circuit is detected, the charger will go into
short circuit protection mode and the Red LED indicator
light turns OFF. The short circuit current ﹤ 600mA/CH.
Reverse Irrigation Current: ≤ 1mA
In normal charging process, when the input power cuts
off suddenly, the current which is released by discharge
is called reverse irrigation current.

4. Care and Maintenance
UDC3 Cleaning
The UDC3 is rated for water resistance. The UDC3 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 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 and
will void the product warranty.
Use caution when cleaning the UDC3; 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 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, other than isopropyl
alcohol.
Drying the UDC3
If the UDC3 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.
CAUTION!
Do not allow the UDC3 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.

PROBLEM POSSIBLE CAUSE ACTION
Loss of Illumination
Battery charge is low Replace batteries with freshly
charged batteries.
Batteries cannot supply sufficient
current at this power setting.
Replace batteries with freshly
charged batteries.
Verify batteries have been installed
in the correct orientation.
Battery mismatch
Reduce the light intensity and
continue using the current battery.
Recharge the batteries as soon as
possible.
UDC3 Light output
flashing
Battery charge is low Reduce the light intensity and
continue using the current battery.
This is normal behavior indicator
when the battery charge is low.
Remaining run time is about 2
minutes.
Recharge the batteries as soon as
possible.
Light Guide does
not attach properly
to the borescope
The borescope has an adapter
on its light post.
Remove the adapter and try
attaching again.
The borescope and UDC3 do
not have a compatible coupling
system.
Use an adapter sleeve or switch
to UDC3 with a different type of
adapter nut.
Light intensity is
low
Foreign material or film on LED
output taper.
VERY carefully clean the LED
surface from visible contamination
with a cotton swap and isopropyl
alcohol. Do not use acetone or
other solvents.
UDC3 becomes hot
after prolonged use
at full power
UDC3 has been left on for more
than 30 minutes at full power.
Turn the UDC3 to a lower intensity
setting if the examination must
continue past 30 minutes.
Turn the UDC3 OFF for a few
minutes to permit adequate cool
down of the body.
