Unit MAY GET HOT. Provide adequate ventilation to prevent overheating.
DO NOT IMMERSE or store liquids above or on the UDC3.
Any changes or modifications made to this UDC3 that are not expressly
approved by manufacturer will void the warranty.
The high intensity light at the front of the UDC3 and at the tip of borescope
will create bright light. To minimize risk of injury, avoid direct viewing or
contact.
This equipment is not suitable for use in the presence of flammable mixture.
2. UDC3 Description, Specications & Accessories

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.

Using the UDC3
1. Turn the UDC3 ON by pressing the GREEN Power ON/OFF button, refer to figure 5.
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.
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.

2.50V-4.55V × 2CH
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.
