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.

•

The mouse cursor can be moved only left &

right during operation (it could Be caused by low
battery or the optical sensor’s data error).

Please take out one of batteries and put it back

for a power reset and then redo the connect
procedure.

•

Mouse does not work after waking up from

power off mode by pressing
The connect button once.

This might be caused by not very precisely

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 27MHz radio-based devices are subject to
interference from other 27MHz 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 27MHz
transmitters. You may need to re-establish the
“connection”.

Note:

Avoid to uses 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.

Note:

* During normal use, please make sure that the

mouse is no more than 3 ft away from the
receiver in order to have reliable connection.

** The LED on the receiver will light up or blink

while the mouse is being used.

Battery low indication

When the voltage level of the battery goes down
under the preset level, the scrolling wheel will flash
at least three times on moving or clicking the
mouse. Although the mouse can still work for a
while, the user should charge the mouse as soon as
possible.

Power off the mouse

To turn off the mouse complete (e.g. for saving the
rechargeable batteries during transportation) go the
following steps:

1. Be sure the mouse is NOT in sleep mode. If it is,

press any key to wake it up.

2. Press and hold the Connect button on the bottom

of the mouse for more than 2 seconds. (The red
light will go off while the Connect button is
depressed.)

3. Wait until the red light flash once. Release the

Connect button.

4. Now, the mouse is in power off mode.

No operation can be done.

Power on the mouse

To activate the mouse again, press the Connect but-
ton on the bottom of the mouse once. (DO NOT
depress the Connect button for more than 1.5
seconds when resuming the mouse from power off
mode.) The red light will turn on, and the mouse is
ready for normal operation.

Operations on power saving mode

In order to conserve battery power, the mouse is desi-
gned to reduce power consumption gradually from
standby mode to sleep mode, if it is not operated.

Standby mode

Around 2 seconds 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 sen-
sor 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 opera-
tion.
