Shimano Wireless Unit (EW-WU111) User Manual

Note:
• This is a small waterproof connector. Do not repeat connecting and disconnecting it. It may impair
the function.
• The components are designed to be fully waterproofed to withstand wet weather riding conditions;
however, do not deliberately place them into water.
• Do not clean the bicycle in a high-pressure car wash. If water gets into any of the components,
operating problems or rusting may result.
• Handle the products carefully, and avoid subjecting them to any strong shocks.
• Do not position the unit on the side of the bicycle frame, as in the illustrations.
If the bicycle collapses, damage to the unit may result if the unit is caught between the bicycle frame
and curbstones etc.

 

• Contact the place of purchase for updates of the product software. The most up-to-date information
is available on the Shimano website.
• Do not use thinners or similar substances to clean the products. Such substances may damage the
surfaces.
• Be careful not to let water get into the terminal.
• Store in a safe place out of the reach of small children to avoid letting them swallow by mistake.
• 2.4GHz digital wireless system
2.4GHz-frequency digital wireless technology, which is the same technology used for wireless LAN.
However, in a very rare occasions, objects and places may generate strong electromagnetic, waves and
interference, which may result in incorrect measurement.
