Adjusting the squelch threshold
Interference due to other transmission links can be eliminated as
follows:
̈ Switch off the transmitter. The receiver should no longer receive a
signal.
̈ If the receiver still receives a signal, use the SQUELCH control ¹ to
increase the squelch threshold so that the signal will no longer be
received. If the signal cannot be eliminated in this way, set the
transmitter and the receiver to a different channel.
̈ Switch on the transmitter again and check if the receiver receives
the transmitter signal.
Note:
If the squelch threshold is adjusted too high, the transmission range
will be reduced. Therefore, always adjust the squelch treshold to the
lowest possible setting.
Selecting a channel
Transmitters and receivers have four channels respectively with
intermodulation-free frequencies.
Note:
These frequencies are different to those in evolution systems and
freePORT systems should not be used together with evolution sys-
tems without great care.
̈ Always set the transmitter and the receiver to the same channel.
Adjusting the transmitter sensitivity
̈ Use the GAIN control ¾ on the SK 2 bodypack transmitter to adjust
the sensitivity so that even during the loudest passages the
AF PEAK LED ¶ on the EM 1 receiver does not light up.
Care and maintenance
Use a slightly damp cloth to clean the units from time to time.
Note:
Do not use any cleansing agents or solvents.
To clean the SKM 3’s sound inlet basket:
̈ Unscrew the sound inlet basket ³ (turn counterclockwise) and
remove it.
̈ Remove the foam insert and use a slightly damp cloth to clean the
sound inlet basket.
̈ Reinsert the dry foam insert, replace the sound inlet basket on the
SKM 3 and screw it tight.
