SCAN & SQUELCH & INFRARED
The function scan initiates an automatic procedure
for the choice of the less noisy channel in
the selected group of channels; the scan
function measures the floor noise of all the
channels of the selected group and show
the result in the display. This is a quick way
to find the best channels to use in the se -
lected group. When pushed the scan but-
ton, it is needed to setup or confirm the
group of channels for the scan.
sQ UELCH initiates the automatic procedure to setup
the level of the squelch. This is an automatic way to
quick setup the squelch for the current frequency.
The transmitter must be off, then push SQ button to
let the system find the optimal value. You can later
accept, modify or discharge this setup.
iR interface window: for communications between
the MRK950 and a transmitter. You have to put the
IR interface of the transmitter, with the IR interface
active, in front of this window. This is needed for
example in the SYNC function.

area a : 3 LED bars:
• two bars for the RF levels in microVolt (diversity
A & B antenna level),
• FM modulation of the received channel (modula -
tion in % referred to the nominal deviation).
area B : LCD display.
