Function
Single Flash
LED flashes when the ME is registered to the UMTS network and either
awake or in power saving state.
Double Flash

GREEN LED
(GSM)
Function
500ms On / 500ms
Off
Flashes at 1Hz and 50% duty cycle when the ME is awake and not registered
to any network.
2s On / 2s Off
Flashes at 0.25 Hz and appr. 50% duty cycle when the ME is in power saving
state and not registered to any network. When the ME is in power saving
state and not registered, the flashing frequency may be less than 0.25Hz and
the duty cycle may vary, for example between 45% and 55%. These
variations are due to transitions from awake state to power saving state
which may occur at the beginning of an LED flashing period (eg. at the
beginning of a 1Hz or 0.25Hz flashing period). In the worst case, the LED will
indicate a transition from awake to power saving after 4s.
Flashing
LED flashes when the ME is registered to the GSM network and either awake
or in power saving state.
While the STATUS0 signal is active the STATUS1 signal is inactive.
Double Flashing
Connected to an ISP
Off
ME is not registered to the GSM network.
