INTRODUCTION
Before using the light, be sure to thoroughly read this instruction
manual and accompanying “Lithium-ion Batteries”.
Thank you for purchasing our CATEYE “SUMO2 HL-EL920RC”.
This product has significantly increased light intensity more than the conventional products, using new multichip LEDs as its light source. It uses highcapacity lithium-ion rechargeable batteries, and is an ideal high-power rechargeable light that delivers superior performance even in a severe environment.
FOR SAFE OPERATION
Do not use it on public roads. This product emits light equivalent to that of automobile headlights, therefore, it is very dangerous depending on the beam angle.
When you use it on public roads out of necessity, be sure to adjust the
beam angle downward so it does not dazzle the oncoming driver.
Never short-circuit the terminals of the battery unit or the battery charger. It may •
cause the unit to overheat, resulting in fire or damage to the component.
The battery unit uses lithium batteries. If liquid leaks from the batteries, do •
not touch them with bare hands and do not bring them close to fire.
Securely connect the plug and fasten the strap. Otherwise, they may come off while riding, •
causing the light to turn off, or you could topple over if the cable gets caught in the wheel.
Never use damaged components (e.g., cables, etc.). Send any damaged •
components to our customer service department for repair.
Do not stare at the light when it is on. Doing so may damage your eyesight.•
The light unit is hot when it is on or immediately after it is turned off; therefore, •
be careful not to burn yourself.
Do not place it within children’s reach.•
Never disassemble the light unit, battery unit, or battery charger.•
Do not store the battery unit in a car or near a heater. Charging, discharging •
and storing at high temperature may accelerate battery deterioration.
When you leave the battery unit for a long time, it self-discharges over time, decreasing •
its voltage. Store the battery unit with the plug disconnected, and charge it before use.
If you are not going to use the battery unit for a long time, use up the batteries and store •
them in a cool and dry place. Charge the batteries for about 5 minutes every 6 months.
If the lamp body or parts become dirty with mud, etc., clean with a soft cloth which is moist-•
ened with mild soap. Never apply paint thinner, benzine or alcohol; damage will result.
When the connecting plug is dirty with mud, etc., clean it with the plug connected and locked.•
This product is water-resistant under normal daily use and can be used in the •
rain. However, do not intentionally submerge it in water.
We recommend carrying a flashlight or spare battery unit with you in case •
the main battery dies.
Mount the light unit and the battery unit, 3cm and 10cm away from the wire-•
less computer, respectively. When they are too close to the computer, its
transmitting and receiving functions may be affected.
Before Initial Use
The battery is shipped with a small charge, that is used to test the unit at the factory. It is necessary to charge the battery before initial use. (Refer to the “How to
charge battery unit” section in this manual.)
HOW TO MOUNT TO A BICYCLE
1
Wind the bracket strap around the handlebar, and put the strap through the opening.1
Screw the dial into the bracket to secure it temporarily.2
Insert the light unit to the bracket until it clicks, and then adjust the beam angle *
(refer to “How to adjust beam angle”).
Securely tighten the dial, and cut off any excess bracket strap.3
To remove the light unit, pull out it forward while pressing the button.*
CAUTION!:
Be sure to tighten the dial by hand. When you tighten it too hard with a tool, •
the screw thread may be stripped.
Check the dial and screw (*1) on the bracket periodically, and use them •
without any loosening.
Round off the cut edge of the bracket strap to prevent injury.•
Make sure the light unit is cool before attaching/removing it.•
2
Connect the plug of the light unit to the battery unit as shown.
CAUTION!: The plug is locked by turning the ring while pressing. It must remain locked in use.
To disconnect the plug, turn the ring in the reverse direction to unlock the plug, *
and then pull out the plug.
3
Put the fixing strap through the strap holder of the battery unit. 1
Install the fixing strap so that the turnback strap faces outside.
Secure the strap holder of the battery unit with the turnback strap of the fixing strap.2
Put the rubber pad of the battery unit on the top tube, and secure it firmly by 3
wrapping with the fixing strap.
Put the auxiliary strap through the strap holder of the battery unit, and secure 4
it firmly by winding it around the down tube.
Wind the auxiliary strap with the battery unit installed as frontward as possible. *
The battery unit will be stably secured during riding.
Secure the cable appropriately to the frame and/or stem with another auxiliary strap.5
The turnback strap of the fixing strap can be also used for securing the cable.*
When the battery unit is not installed directly to the frame, the rubber pad of a *
battery unit can be removed.
CAUTION!:
Be sure to firmly secure the battery unit. When the battery unit is secured •
insufficiently, it may be dislocated on impact while riding.
When some cables are installed along the top tube, attach the cable cover in •
advance to protect the cable from any force applied. Otherwise, it may cause
trouble in braking or gear shifting.
Pay attention to the arrangement of the cable so that it does not interfere with •
the handling of the bicycle. Do not secure the cable at an acute angle because
the wire inside the cable may break.
Adjust the beam angle before use according to the description in “How to •
adjust beam angle”.
