Charge the Battery (China Only)
Please install the battery by referring to the introduction in “Use the Battery”.
Then, connect the AC power and turn on the power switch at the rear panel to
charge the battery. At this point, the power key at the front panel can be in
any state.
The battery status indicator at the front panel indicates the charge
progress. If the battery status indicator does not go on, the battery contains
no electricity currently. If the battery status indicator still does not go on after
the battery has been charged for half an hour, please cut off the AC power and
check whether the battery is correctly installed or whether it is damaged.
No matter whether the spectrum analyzer is in start-up or standby state,
about 10 hours are required for the battery to be fully charged.
