The actual battery life may vary depending on circumstances of use.
Replace the batteries
When the batteries become weak, the sound may become weak or distorted, and
"E" will flash in the display. After that, when the batteries are used up, "E"
will light up and clock time display appears. And then the cycle-computer
function will be stopped so that any button functions will not work. The Radio
function will be also turned off if it is on. If this happens, replace the batteries
with new ones.
After the batteries are replaced, press RADIO POWER, RESET, or install the
unit on the Mount. ("E" turn off in the display.)
Note on replacing the batteries
Do not take more than 5 minutes to replace the batteries, otherwise, the clock
setting will be initialized. Should that happen, reset the functions.
Notes on batteries
· Do not charge the dry batteries.
· Do not carry the dry batteries together with coins or other metallic objects. It
can generate heat if the positive and negative terminals of the batteries
accidentally come into contact with metallic objects.
·When you are not going to use the unit for a long time, remove the batteries to
avoid damage from battery leakage and corrosion.
· Do not use different types of batteries at the same time.
·When you replace the batteries, replace all with new ones.
Installing the unit on the
Install the Wheel Magnet
1 Remove the screw of the wheel magnet and open.
2 Attach the magnet between two spokes of the front wheel with the
head of the screw facing inward, and tighten the screw.
Install the Mount
1 Choose the appropriate rubber pads according to the diameter of the
handlebar and attach them.
Use one or two rubber pads depending on the diameter of the handlebar. You
can attach the Mount clamps without the rubber pads if not required.
The Mount clamps are adjustable. You can adjust the width of the clamps to
fit your handlebar.
2 Install the Mount on the rubber pads and secure with the 4 screws.
3 Wind the sensor cord around the break cable.
Be sure to allow enough cord slack to ensure full movement and unhindered
operation of the handlebar, and not to wind it too loosely as this may interfere
with the unit's operation.

Cautions on Water-resistance
This unit is designed so that it can be used with slight exposure to rain, snow and
other forms of moisture, but there are several points on which caution should be
· Do not allow it to come into contact with large amounts of water.
· Do not immerse it in water.
· If water should get on it or if it should fall into water, take it out immediately
and wipe it off with a dry cloth. To prevent the battery from corroding, wipe out
the interior of the battery compartment as follows:
Open or close the battery compartment with dry hands in a place without
exposure to any water.
Wipe off the battery and the inside of the battery compartment. Give special
attention to the contacts so that no water remains on them.
Notes on the cycle-computer radio
·The user must obey all traffic laws when using the device.
·To check whether the local laws allow the use of the device.
· In order to prevent dangerous condition, do not operate the device when
running the bicycle.
· In order to prevent theft, take your device with you at all times.
