The SR 40 FLEXX is a stationary diversity receiver for use with all WMS
40 FLEXX and Microtools Series transmitters. It features a half-rack case
for mounting in a 19" rack.
Operating in the 660 MHz to 865 MHz UHF range, the SR 40 FLEXX pro-
vides three selectable, quartz stabilized carrier frequencies within the 3-
MHz-wide frequency band for which you ordered your WMS 40 FLEXX.
This allows you to select a different frequency if one of the three frequencies
does not provide adequate signal quality. The frequencies have been fac-
tory preset to make sure you can set up a multichannel system with up
to three channels with three kits operating in the same frequency band.
Using a suitable combination of kits operating in different frequency bands
you can even use up to nine channels simultaneously.
The SR 40 FLEXX is a diversity receiver and uses two antennas in order
to receive the transmitter signal at two different spots. The diversity elec-
tronics will automatically activate the antenna that delivers the better signal.
An adjustable squelch will mute the receiver if the received signal is too
weak so the related noise or the self-noise of the receiver will not become
audible when the transmitter is switched OFF.
1 Antennas: Fixed-length UHF antennas permanently mounted on the
front panel. The diversity circuit will automatically activate the antenna
that provides the better signal.
2 ON/OFF: On/off pushbutton switch. If the DIVERSITY LEDs A and B
flash alternately and the RF MUTE LED is lit constantly, the receiver
is ON but receives no signal.
If the RF OK, AF OK, and only one of the two DIVERSITY LEDs are lit,
the receiver is ON and receives signal.
When you switch the receiver OFF, all LEDs will extinguish.

3 RF LEDS: These LEDs indicate the quality of the received RF signal.
3a OK (green): This LED is lit to indicate that an RF signal of adequate
strength is being received.
3b MUTE (red): This LED is lit to indicate that no signal is being re-
ceived or the squelch is active. In either case, the audio output will
be muted automatically.
4 DIVERSITY LEDs A and B: Indicate which of the two receiving an-
tennas is active at any time.
