Hitachi CMU Series User Manual page 15

(chapter 4, page 4-9)
After setting in the [Communication type] window, a session of communication
with the CMU starts to collect [[S10V] S10BASE] window display information. If
the CMU is inactive or there is an invalid setting of communications information,
the [[S10V] S10BASE] window is displayed in online state after a communication
timeout is detected. Depending on the setting of the communication type, the
communication timeout may take 2 to 3 minutes to detect.
(chapter 4, page 4-13)
The battery module's remaining life (hours) presented in the [CMU battery
information] window is only a rough estimate and does not guarantee its actual
remaining life or backup efficacy. The battery module's useful life varies
depending the ambient temperature and humidity, so it is recommended that the
battery module should be replaced periodically.
(chapter 4, page 4-22)
The functions described in Subsections 4.2.10 through Subsections 4.2.14 are
available for CMU and model-LQE720 ET.NET modules, but they are not
available for model-LQE520 ET.NET modules.
(chapter 6, page 6-2)
Static electricity may damage the module. Before starting the work, discharge
