3 Setting Up
• If OK (6a) is lit constantly and CLIP (6b) flashes frequently or is lit constantly, the trans-
mitter input gain is too high. Set GAIN (18) to "LOW".
6. Set the levels on your mixer or amplifier referring to the appropriate instruction manual,
or by ear.

1. Pull the color code clip (1) off the transmitter case in the direction of the arrow.
2. Slide the supplied semitransparent replacement clip onto the transmitter to the point
that it snaps into place with an audible click.
1. Move the transmitter around the area where you will use the system to check the area
for "dead spots", i.e., places where the field strength seems to drop and reception de-
teriorates.
If you find any dead spots, try to eliminate them by repositioning the receiver. If this does
not help, avoid the dead spots.
2. The RF OK LED on the receiver going out means no signal is being received or the
squelch* is active.
Switch the transmitter on, move closer to the receiver, or set the squelch threshold* to
the point that the green RF OK LED will be lit.
3. HT 40 FLEXX + SR 40 FLEXX: If the received signal is noisy, set the squelch threshold
to a level where the noise will stop.
L
• HT 40 FLEXX + SR 40 FLEXX: Never set the squelch threshold any higher than ab-
solutely necessary. The higher the squelch threshold (-70 dB = max., -100 dB =
min.), the lower the sensitivity of the receiver and thus the usable range between
transmitter and receiver.
In each frequency band, the spacing between the three carrier frequencies of all WMS 40
FLEXX transmitters and receivers is wide enough for operating three radio channels simul-
taneously with no mutual interference.
Note: For systems with up to nine channels you will need WMS 40 FLEXX kits in up to three dif-
ferent frequency bands. Please ask your dealer which frequency bands are suited for mul-
tichannel use and approved for the place where you will use the system. Perform steps 1
through 6 below for each frequency band separately.
1. Switch power to all transmitters and receivers off.
2. Set the frequency selectors on the transmitter and receiver for channel 1 to "1".
3. Set the frequency selectors on the transmitter and receiver for channel 2 to "2".
