DETERMINE MERLIN STATES

In This Section
• Determine the current state of your UMTS Merlin, by interpreting the cadence (flashing sequence) and
colour of the Light Emitting Diode
The Light Emitting Diode (LED) is a device that lights up when power is applied to it. Interpreting the LED's
flashing sequence and color, will provide you with the current state of your UMTS Merlin. See Table 1 below.
