automatic fade-in feature is activated. The transmission path has preference over the
surrounding noises transmitted by the built-in microphone.
In addition, L1 also serves as an adjustment aid for the microphone sensitivity at the
Transmitter SK 2013 PLL. (Also see Page 14)
Squelch and battery check, red led
L2 has the dual function „squelch indicator" (activated squelch) and „LowBat"
indicator for battery check with tendency recognition:
• constant red light Squelch switched on = no reception
• flashing red light slow flashing:
Both indicator lamps are arranged on the front of the receiver so that they can also be
dependably seen over a greater distance by the person equipped with the transmitter.
In this way it is easy to ascertain whether the speech connection exists.
