1.5.2 Battery Status LED
The Battery Status LED displays the current status of the
Ni-MH Battery Pack:
Red:
The battery pack is not charging for one of the following reasons:
• When starting to charge, the temperature of the battery pack is lower
than 5°C or higher than 45°C.
In this situation, disconnect the AC
adapter from the Network Master and wait until the temperature of
the battery pack is within the 5° to 45°C range.
• While charging, the temperature of the battery pack becomes lower
than 5°C or higher than 60°C.
In this situation, charging resumes
automatically as soon as the temperature of the battery pack is within
the 5° to 45°C range.
• Charging has not finished within the about 3 hours it normally takes
to charge the battery pack fully. To avoid overcharging, the unit stops
charging after about 3 hours.
If the Battery Status LED is always red, there is a problem with the
battery pack. Please contact the Anritsu Technical Support Center or
your local Anritsu representative (see Anritsu Corporation Contact).
Orange
• The AC Charger/Sdapter is plugged in and the battery pack is
charging.
Green
• The AC Charger/Adapter is plugged in and the battery pack is fully
charged or the Network Master is operating. The battery pack will
continue charging in maintenance charge mode.
Note
Charging or discharging can be started at any time with minimum
battery memory issues. The battery pack can be left in
maintenance charge indefinitely.
