Adjusting the squelch threshold

Interference due to other transmission links can be eliminated as

follows:

왘 Switch off the transmitter. The receiver should no longer receive a

signal.

왘 If the receiver still receives a signal, use the SQUELCH control  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.

왘 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.

왘 Always set the transmitter and the receiver to the same channel.

Adjusting the transmitter sensitivity

왘 Use the GAIN control  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:

왘 Unscrew the sound inlet basket  (turn counterclockwise) and

remove it.

왘 Remove the foam insert and use a slightly damp cloth to clean the

sound inlet basket.

왘 Reinsert the dry foam insert, replace the sound inlet basket on the

SKM 3 and screw it tight.
