Receiver Description

Power LED

• This indicator light is off when the ProFlex 800 is off and

no external power source is connected to the DC power
input.

• It is on and red when an external power source is present

at the DC power input and the ProFlex 800 is off.

• It is on and green when the ProFlex 800 is on, regardless

of whether it is powered from the internal battery or an
external power source.

• It is blinking red when the sleep mode has been enabled

and the receiver is currently running a session. With the
sleep mode enabled, the receiver is idle between any two
sessions, as if it were virtually turned off, and the power
LED is also turned off during this time.
