5.04 USING THE M30 TRANSMITTER WITH THE M131SW MICROPHONE
5.04.1 When the M131SW Microphone is used with an M30 Series Transmitter, it must be connected to the transmit­
ter with the MC-38 cord supplied.
6. R300 WIRELESS RECEIVER MODULE OPERATION
6.01 INITIAL ADJUSTMENTS
To place the R300 Wireless Receiver Module into operation, perform the following procedures:
(a) Extend the antenna fully and ensure it is not touching any metal objects.
(b) On the R300 module, rotate the VOLUME control fully counter-clockwise.
(c) On the VP300 AMplifier Module ­
(1) Insert the CH-40 charger plug fully into the CH-40 IN jack. Plug the charger into the AC wall socket. The
green lamp will light and remain lit if the battery pack requires charging. If the battery pack is fully charged,
the lamp will light momentarily and then go dark.
(2) Operate the POWER switch to ON. The associated red POWER lamp will light. In this mode of operation the
unit is operating from AC power and the battery pack is being charged. If a power failure occurs, the unit
automatically switches over to battery operation.
(3) For battery only operation, disconnect the CH-40 charger. In this mode of operation a fully charged battery
pack will typically provide 12 hours of operation. One hour of charge will typically provide two hours of opera­
tion.
(d) On the R300 module, operate the POWER switch to ON. The associated red POWER lamp will light.
(e) On the M30 transmitter, operate the toggle switch to ON.
(f) On the R300 module, rotate the VOLUME control clockwise until the green lamp lights.
6.02 ADJUSTING THE R300 VOLUME
6.02.1 Establish the speaking location and, while transmitting from that position, adjust the VOLUME control on the
R300 module until intelligible sound, at an adequate level, is available at the most distant point a listener is expected.
6.02.2 Avoid feedback by adjusting the VOLUME control no higher than necessary. A setting between 20 percent and
60 percent of full range will provide the best signal-to-noise ratio with the lowest distortion.
6.03 OPERATING THE FM-AV5 BY MORE THAN ONE PERSON
6.03.1 If desired, the FM-AV5 may be operated by up to three persons - two using M121S microphones plugged into
the VP300 amplifier module and the third person using the M30 Series Transmitter with the appropriate microphone.
6.04 USING THE M30 NEAR THE FM-AV5
6.04.1 When it is necessary to operate the transmitter at close range, a feedback problem may be encountered. This
can be minimized by using the Lectrosonics Model HM-142V Headset Microphone which has a volume control. With
the HM-142V volume control and the R300 module volume control properly adjusted, it is possible to work within a
few feet of the receiver.
