3 Setting up
1. Check that the carrier frequency (frequencies) of the transmitter is (are) identical to the
receiving frequencies of your SR 40 FLEXX.
The carrier frequency (frequencies) of the transmitter and the receiving frequencies of
the receiver are indicated in MHz on the respective frequency stickers and in the re-
spective Manual Supplements.
2. HT 40 FLEXX and PT 40 FLEXX:
• Set the frequency selector on the transmitter and the frequency selector (8) on the
receiver to the same positions (1 - 1, 2 - 2, or 3 - 3).
HT 40 PRO, PT 40 PRO, Microtools:
• Switch power to the transmitter and receiver ON.
• If the RF MUTE LED (3b) on the receiver is lit, set the frequency selector (8) on the
receiver to a position where RF MUTE (3b) goes out and the RF OK LED (3a) comes
on.
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 (3a) 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 (3a) will be lit.
3. If the received signal is noisy, set the squelch threshold to a level where the noise will
stop.
L
• Never set the squelch threshold any higher than absolutely necessary. The higher
the squelch threshold (-70 dBm = max., -100 dBm = min.), the lower the sensi-
tivity of the receiver and thus the usable range between transmitter and receiver.
The spacing between the three frequencies of each WMS 40 FLEXX transmitter and receiver
is wide enough for operating three radio channels simultaneously within the same frequency
band with no mutual interference.
• For systems with up to nine channels you will need WMS 40 FLEXX kits in up to three
different frequency bands. Please ask your dealer which frequency bands are suited for
multichannel use and approved for the place where you will use the system. Perform
steps 1 through 6 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".
4. Set the frequency selectors on the transmitter and receiver for channel 3 to "3".
5. Set up the transmitter and receiver for channel 1.
6. Repeat steps 1 through 5 for channels 2 and 3.
L
• Do not operate two or more wireless channels on the same frequency at the same
time and location. This would cause unwanted noise due to radio interference.
• Prior to changing a carrier frequency, be sure to switch the transmitter off. To activate
the new carrier frequency, switch the transmitter back on.
