*When the CU-321 is powered from the USB host (PC) or USB hub.
If the CU-321 is self-powered via the USB interface from the USB host (PC) or USB hub and the host PC
is in suspend mode, then the CU-321 cannot charge the battery cartridge.
If the host PC switches to the suspend mode when the CU-321 is charging the battery cartridge, then the
CU-321 will stop charging. When the host PC recovers from the suspend mode, the CU-321 will start
charging again. To prevent the CU-321 from getting affected by the suspend mode, use the dedicated
AC adapter.
