TO ENSURE SAFETY
SM-BCR2: Battery charger for SM-BTR2/BT-DN110/BT-DN110-A
• Do not use any USB cable other than the USB cable which is supplied with the PC linkage
device. This may cause a charging error, fire, or failure to connect to PC due to
overheating.
• Do not connect the battery charger to PC when it is on standby. This may cause a PC
failure depending on its specifications.
• When connecting or disconnecting the USB cable or the charging cable, be sure to hold
the cable by the plug. Failure to do so may cause a fire or electric shock.
If the following occurs, stop using the device and contact your place of purchase. A fire
or electric shock may occur.
* If heat or acrid-smelling smoke is coming out from the power plug.
* There is a bad connection inside the power plug.
• If it thunders while charging with an AC adapter with a USB port, do not touch the
device, bicycle, or the AC adapter. If lightning strikes, electric shocks may occur.
• Use an AC adapter with a USB port that has a voltage of 5.0Vdc and a current equal to or
higher than 1.0Adc. If the one with a current lower than 1.0Adc is used, a charging error
may occur or the AC adapter may heat up, leading to a fire.
• Do not use a USB hub when connecting the cable to a computer USB port. This may cause
a charging error or fire due to overheating.
• Be careful not to damage the charging cable. (Do not damage, modify, let near hot
objects, bend, twist or pull them; do not place heavy objects on top or bundle them
tightly.) If they are used while damaged, fire, electric shocks or short-circuits may occur.
„ Brake
• Each bicycle may handle slightly differently depending on the model. Therefore, be sure
to learn the proper braking technique (including brake lever pressure and bicycle control
characteristics) and operation of your bicycle. Improper use of your bicycle's brake system
may result in a loss of control or a fall, which could lead to severe injury. For proper
operation, consult a professional bicycle dealer or the bicycle's owner's manual. It is also
important to practice riding and braking, etc.
• If the front brake is applied too strongly, the front wheel may lock and the bicycle may
fall forward, and serious injury may result.
• Always make sure that the front and rear brakes are working correctly before riding the
bicycle.
• The required braking distance will be longer during wet weather. Reduce your speed and
apply the brakes early and gently.
