Renishaw RCU10, Installation And User Manual, Page: 85 / 202

6-6 Operation
6.3 General maintenance
The RCU10 system requires no routine maintenance. If any fault is present in the system,
it will normally be indicated by one of the error status signals which may be monitored via
the machine control or the RCU CS software display.
It is recommended, however, to periodically verify the correct operation of the system and
environmental sensors, as any fault here may cause an inaccuracy in the feedback
system. The frequency of this verification is dependent on the nature of the application.
Note: The RCU10 contains a lithium metal battery. Please contact Renishaw for details of
battery replacement. (The customer must not change the battery). Typical battery
life is ten years. At end of life the RCU10 must be disposed of in accordance with
local regulations.
The use of this symbol on the batteries, packaging or accompanying
documents indicates that used batteries should not be mixed with
general household waste. Please dispose of the used batteries at a
designated collection point. This will prevent potential negative effects
on the environment and human health which could otherwise arise from
inappropriate waste handling. Please contact your local authority or
waste disposal service concerning the separate collection and disposal
of batteries. All lithium and rechargeable batteries must be fully
discharged or protected from short circuiting prior to disposal.
