Precaution
The optical mouse can not work on a glass or mirror surface. Avoid operating this
mouse on a glossy surface; otherwise, this mouse may not operate normally.
For consideration of saving battery power, it is strongly recommended to operate an
optical mouse on a bright surface with fine texture to obtain lower power consumption of
the high illumination LED. A very dark surface will cause higher power consumption.
For optimal performance, place the receiver at least 8 inches or 20 centimeters
away from other electrical devices, such as the computer, the computer monitor,
speakers or other external storage drives.
For a better transmission distance, avoid using this device on a metal plate or
desktop because a large surface of iron, aluminum, copper and other metal will act as a

shield or ground to the RF antenna of the mouse and receiver. Operating on a metal
surface may shorten the transmission distance.
If your notebook computer has a metal (contains Al or Mg) case, the metal housing
of the LCD panel will isolate partial radiation of the RF signal from the mouse. This could
possibly result in reducing the distance of transmission when you operate the mouse
right in front of the notebook and when the receiver is connected on the back of the
notebook. However, the RF mouse should work properly while you are operating the
mouse just beside your desktop computer.
Battery Warning!
When replace the batteries, use alkaline. You may use rechargeable NiMH or
other type of batteries, but do not mix then with alkaline. Do not mix used and new
batteries together!
BEFORE YOU BEGIN
Keep this installation guide for future reference! It contains Important
Troubleshooting Information.

Operation Guide
Mouse Button Definition
MOUSE BATTERY LOW INDICATION
When battery voltage level goes under the preset level, battery indicator

LED on the wheel of the mouse will flash frequency when moving or clicking the
mouse. Although the mouse can still work for a while, the user, at this time,
should have a new set of batteries ready for replacement as soon as possible.
POWER ON/OFF MOUSE
DC103 designed for power saving, you can power ON/OFF by sliding
ON/OFF switch on the mouse bottom.
OPERATIONS ON POWER SAVING MODE
In order to conserve battery power, the mouse is designed to reduce power
consumption gradually from standby mode to sleep mode, if it is not being used.
Standby mode – Around 1 second after the mouse stops moving, it enter into
standby mode.
Sleep mode – If the mouse is left intact for around 8 minutes, it goes to sleep
mode and shuts down the optical sensor to maintain minimum power
consumption. No moving operation is possible in this mode.
Wake up the mouse – This mouse can work promptly under Standby mode so
users might not be able to tell the existence of this mode. But, in sleep mode,
users have to press any button to wake up the mouse for normal operation.

TROUBLESHOOTING
1. Mouse does not function 
If mouse is not functional, please turn off the computer first.  Check the
receiver and make sure it is firmly attached to the USB port of the computer.
 Check the placement of batteries and see if they are properly connecting.
 The "+" and "-" on the batteries must match the "+" and "-" on the slots. If
the batteries aren't inserted correctly, the device won't work.
 Restart the computer again. If the LED inside the receiver does not light
up when moving the mouse, please re-connect the mouse to the receiver.
Q: The mouse cursor can only move left & right during operation (it could be

caused by low battery or the optical sensor’s data error).
A: Please take out one of batteries and put it back for a power reset and then
redo the connect procedure.
Q: The mouse does not work after waking up from power off mode by pressing
the connect button once.
A: This might be caused by imprecisely depressing the connect button
to wake up the mouse. Users can gain back normal operation by pressing
connect button on the mouse first, and then pressing the one
on the receiver. As soon as the LED inside the receiver starts flashing, the
mouse is ready to operate.
Optical Sensor Mouse functions best on surfaces with details for tracking. It may not
function on reflective, reflective pattern or non-visible detail surfaces!
2. Reducing Interference with Other Wireless Devices
Reducing Interference with Other Wireless Devices:
All 2.4GHz radio-based devices are subject to interference from other 2.4GHz
radio-based devices, such as cordless telephones, cordless baby monitors,
and cordless toys. It may help to move the receiver unit and the base unit of
other wireless devices (such as cordless telephone cradle) as far apart as
possible. You may need to try several times for a location that is best in your
operating environment.
Move the receiver and the mouse closer to each other so that the receiver
is relatively shorter in distance to the mouse than to other 2.4GHz transmitters.
You may need to re-establish the “connection”.
Note: Avoid using this device on a metal surface because a large surface of iron,
aluminum, copper, or other metal may act like a shielding to the RF antenna of the
mouse and the receiver.
3. Interference with other RF wireless mouse
If the interference comes from other same model of RF wireless mice, please
“Setting up connection between mouse and receiver” of the installation guide
to switch to a new RF channel. A new identification code is also generated

upon the completion of channel switching. Normally, the effective transmission
distance is about 3 feet, depending on the environment. If the effective
distance between the mouse and the receiver is bad, try to change the
location of the receiver.
4. If you have difficulty connecting the wireless mouse:
Increase the distance between the set of wireless mouse and other radio
device units.
Turn off the other wireless devices, or their base units that are in close
proximity to the receiver of this wireless mouse. Try connecting the wireless
mouse and its receiver again. To verify that your device is connected and
working properly, open a document and try the device.
5. My keyboard or mouse does not work or does not work properly after
installation
Make sure you have connected the receiver correctly. For optimal
performance, place the receiver at least 8 inches or 20 centimeters away from
other electrical devices, such as the computer, the computer monitor, or
external storages devices.
Make sure you have installed the batteries correctly.
Make sure you have set the same ID on both transmitter (mouse and
keyboard) and the receiver (see setting the ID under Hardware Installation).
If the problem persists, try an alternative ID selection to avoid possible
interference. Remember to set the same ID or both transmitter and receiver.
6. My keyboard or mouse is not detected
Make sure you have connected the receiver correctly. Do not plug or unplug
the receiver cables while the computer is running. You may have other system
devices that conflict with the mouse and keyboard. Check the IRQ / address
settings of these devices for conflicts and change the settings as required.
