INSTRUCTION MANUAL
READ ALL INSTRUCTIONS BEFORE FIRST USE
Thank you for purchasing the CAT EYE TWIN / SOLO Model HL-NC250/260. Designed for high performance night
cycling, this rechargeable lighting system adopts powerful halogen bulb technology. This is a unique high power 12 volt
system. Before operating, thoroughly familiarize yourself with this manual so that you understand the light's safe and
correct operation. Please keep this manual, along with the warranty card, for future reference.
FOR SAFE OPERATIONS (IMPORTANT)
Warning!!!
• The lamp body becomes extremely hot when turned on. Never touch the lamp body or lens until
thoroughly cooled. Injury may result.
• Stop using the light at once if the lamp unit, cord or bottle battery is broken.
• Use only the included battery charger for charging.
• Never short-circuit the terminal of the bottle battery and the plug of the battery charger. It may
cause the battery to over heat, resulting in fire or damage of the components.
• When the battery comes to the end of its useful life, turn the bottom of the bottle battery counter-
clockwise and take out the inside battery. Safely and properly dispose of the old battery.
• Never place it within children’s reach.
Important Note
• When using this light on public roads, be sure to adjust the angle of the beam downward so as not
to blind oncoming traffic.
• Never disassemble the lamp body or bottle battery for the purpose of modification.
• Never use the bottle battery with other equipment.
• Although the lamp body and the battery are water-resistant (normal weather conditions of rain,
etc.), never intentionally submerge them under water.
• Never touch the halogen bulb with bare-fingers; natural skin oils can cause the bulb to over heat and break.
• Never touch or wipe the inside of the reflective mirror. This may degrade the quality of the light output.
• Ni-Cad batteries have unique characteristics. The light output will remain high until just the batter-
ies run out, and then drop suddenly. Take precautions against such a situation by preparing a
spare light or spare bottle battery.
• Use only the included battery charger for charging. Never charge the battery for more than 24
hours. After charging, be sure to unplug the charger from the outlet.
• A long period of non-use will lower the voltage of the battery due to natural self discharge. Always
charge the battery before using.
• The operation time and charging time may vary with the environment.
• Overdischarge (leaving the light on after the power is completely gone) shortens the performance
life of the battery.
• If the lamp body or parts become dirty with mud, etc., gently wipe it away with a dish towel which is
moistened with mild soap. Never apply paint thinner, benzine or alcohol; damage will result.
BEFORE FIRST USE:
The factory-loaded battery is not fully charged; the charge is useful only for a short period
of time. Before first use, charge the battery fully following the instructions on [HOW TO CHARGE].
HOW TO ATTACH THE BRACKET
Lamp Bracket
(Use both of the two brackets for NC250)
There are two ways of mounting the lamp unit to bicycle; on top of the bars
or under the bars. Make sure no cables touch the lamp body. (If brake wire
hinders the installation of the "mounting under the bars", use the optional
extension spacer.)
1. Attach the bracket (H-27) to the handlebar using the appropriate rubber
pads provided. Hand-tighten the bolt.
2. Before tightening the bolt, adjust the angle of the beam and the position
of the lamp body. (Before using, readjust the angle according to the in-
struction of "Angle of Beam" in "HOW TO USE" section.)
3. Tighten the bolt securely. (For a more secure fit, use a screwdriver.)

Warning!!!
Never touch the lamp body until thoroughly cooled. You may get burnt.
1. To install, slide the lamp body forward onto the lamp bracket until it clicks into
position. Do the same thing with the switch.
2. To remove the lamp body, slide it backward while pushing the lever. Be sure to
remove the switch together.
Connecting the Jack
After connecting the jack to the plug, wind the cord round the frame so that it will
not hinder riding.
Note: Securely connect the jack to the plug.
HOW TO USE
How to Switch on/off
• To switch on/off, press the swicth button.
• With the HL-NC250 TWIN, the two buttons operate as follows:
Yellow Button: 20W
Grey Button: 12W
Note: In case the light does not turn on, charge the battery.
Angle of Beam
Switch on the light at night in flat place, and adjust the angle vertically. (It is also
adjusted 10
°
horizontally.) To adjust, loosen the screw of the bracket a little.
Warning!!!
In addition to its high brightness, the beam is widely
diffused. When using this light on public roads, be sure to adjust the
angle downward so as not to blind oncoming traffic.

Switch Bracket:
Attach the switch bracket (with the switch on it) on the handlebar. Be careful not
to hinder the braking or shifting operation.
1. Use the appropriate rubber pad provided. Tighten the bolt.
2. To remove the switch from the switch bracket, slide it sideway while pushing
the lever (as shown in the figure).
* When removing the switch, remove the lamb body together.
HOW TO MOUNT
Mount the bottle battery into your bottle cage, the lamp body to the lamp bracket
and the switch to the switch bracket. Connect the jack to the plug.
Bottle Battery
Insert the battery into your bottle cage and fix it tightly with the battery belts.
Note: While riding, the bottle battery may jump out of the bottle cage by a
strong impact. Be sure to fasten it securely with the belts.

REPLACING BOTTLE BATTERY
By preparing a spare bottle battery, you can continue to use the light and the time for
night riding will be extended.
1. Turn the battery cap counterclockwise and open it.
2. Disconnect the inside jack and replace the bottle battery.
Note: After replacing, securely connect the jack again.
Note: When closing the battery cap, be careful not to catch dust around the rubber
ring.
* The bottle battery can be charged without the battery cap. In this case, connect
the plug of the charger directly to the jack inside of the bottle battery.
HOW TO CHARGE
Use only the included battery charger in an AC outlet for charging.
1. Insert the plug of the battery charger into the jack of the bottle battery (or
the jack inside of the battery cap).
2. Plug the battery charger into an AC outlet.
* The standard charging time is 8 hours if no charge is left in the battery. Never
charge the battery for more than 24 hours; battery damage will result.
3. After charging, unplug the battery charger and pull out the plug.
Note: Be sure to unplug the battery charger after charging.
Note: To make full use of the bottle battery's capacity, recharge after the
battery's whole capacity has been consumed. If the battery does not serve
the proper run time even after it has a full charge it may be at the end of
it's useful life. Replace it with a new one. Recharge / Discharge Number
of Times: at least 500 (until rated capacity drops to 50%)
HOW TO REPLACE THE BULB UNIT
When replacing the bulb unit, disconnect the jack from the plug. Be sure the lamp body
and the bulb have cooled before replacing.
1. Turn the socket holder counterclockwise and remove it.
2. Turn the lock ring counterclockwise and remove it.
3. Pull out the bulb unit from the lamp body and remove it from the
unit holder.
4. Insert a new bulb unit into the unit holder and fix it with two screws.
Note: Never touch the halogen bulb with bare-fingers; natural skin
oils can cause the bulb to over heat and break. Never touch or
wipe the inside of the reflective mirror. This may degrade the qual-
ity of the light output.
5. Make sure if the rubber ring A/B is properly aligned. Install the lock ring, and tighten it.
6. Install the socket holder and tighten it.
Note: For the best performance of waterproofing, securely tighten all the parts. If water
leaks into the inside of the bulb unit, it might result in damage of the components.
SAFETY SYSTEM
(AUTO-RESET FUSE)
When an electrical surge/malfunction occurs in the circuit or the temperature of the bat-
tery rises, the fuse blows because of its safety system and the circuit will be closed. In this
case, switch the lamp off, find the cause of the malfunction and remove it. After leaving it
for a while, the fuse will automatically recover.
Note: If the fuse blows even after the malfunction is removed, or if the fuse does not
recover, call the appropriate service center for assistance.
