1.4 The Two System LEDs
The two System LEDs provide an alternate way to indicate power status of your system
unit as also provided by the Power LED as described in Chapter 1.3. The table below
illustrates how these two System LEDs behave in different situations.

is not inserted, or
• The battery is fully charged.

per 3 seconds The battery is in use (discharging) and the system is not
connected to AC power.
