Actual running time may differ, depending on battery age, charge condition,
ambient temperature, and other factors.
If the 9433 is connected to the 8841/8842, and the adapter switch is turned
on, even when the 8841/8842 runs off the AC power supply, the 9433
remains in standby mode and consumes some power.
In this case, the battery operation time is 95 hours.
