TO ENSURE SAFETY
• Keep away from magnetic objects. If this is not observed, problems with operation may
occur.
If the product includes a magnet, make sure to use the included magnet to install it in
the specified location.
• Contact the place of purchase for updates of the component software. The most up-to-
date information is available on the SHIMANO website.
• Products are not guaranteed against natural wear and deterioration from normal use
and aging.
• For maximum performance we highly recommend SHIMANO lubricants and maintenance
products.
„ Lithium-ion battery
• Lithium-ion batteries are recyclable, valuable resources.
For information on used batteries, contact the place of purchase or a distributor.
• Charging can be carried out at any time regardless of the amount of charge remaining.
Always be sure to use the special battery charger to charge the battery until it is fully
recharged.
• The battery is not fully charged at the time of purchase. Before riding, be sure to fully
charge the battery.
• If the battery has become completely empty, charge it as soon as possible. If you leave
the battery without charging it, it will cause the battery to deteriorate.
• The battery is an exhaustible item. The battery will gradually lose its capacity to charge
after repeated use. If the length of time that the battery can be used becomes extremely
short, it has probably reached the end of its life, and so you will need to purchase a new
battery.
• The life of the battery will vary depending on factors such as the storage method, the
usage conditions, the surrounding environment and the characteristics of the individual
battery pack.
• If storing the battery away for a long period, remove it when the battery level is 50% or
higher or when the green indicator is illuminating in order to prolong its useful life; and
it is recommended that you charge the battery about every six months.
• If the storage temperature is high, the performance of the battery is reduced, and its
useable time will be shorter. When you use the battery after a long storage period, store
the battery indoors where the battery will not be exposed to direct sunlight or rain.
• If the ambient temperature is low, the battery's usable time will be shorter.
