2 Description
2.4.1 Front Panel
Fig. 1: Front panel controls on
SR 40 FLEXX receiver.
1 Antennas:
Fixed-length UHF antennas permanently mounted on the front panel. The di-
versity 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 re-
ceived.
3b MUTE (red):
This LED is lit to indicate that no signal is being received 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 antennas is active at any
time.
5 Color code:
The color indicates the carrier frequency band of the receiver. Transmitters
and receivers tuned to the same frequency band are marked with the same color. Refer
to the Manual Supplement sheet for a color code table.
6 AF LEDs:
Indicate the received audio level:
6a OK (green):
-30 dB to +3 dB
6b CLIP (red):
>3 dB. This LED illuminates to indicate the audio level of the received sig-
nal is overloading the receiver's audio section.
The green AF OK LED being lit and the red AF CLIP LED flashing occasionally indicate
optimum modulation.
If none of the LEDs is lit, the gain setting on the transmitter is too low.
7 VOLUME:
This rotary control adjusts the receiver’s output level from microphone to line
level for matching to the input sensitivity of your mixer or amplifier. The control range is
26 dB.
8 Frequency selector: This slide switch tunes the receiver to one of three different carrier
frequencies within the receiver's carrier frequency band.
