THE PFM T31 TRANSMITTER
The PFM T31 Transmitter is a battery-powered body-pack model used with a microphone to pick up
the tour guide's voice. The transmitter produces an FM radio signal to broadcast the tour guide's
voice to the receiver units. A simple slide switch on top of the transmitter turns the unit on or off.
The PFM T31 operates on two AA non-rechargeable alkaline batteries (BAT 001), or two AA
rechargeable NiMH batteries (BAT 026).
MICROPHONES
A noise-cancelling, headband microphone (MIC 086) is the standard microphone. The noise-can-
celling microphone helps to reduce background sounds in noisy environments. The microphone
plugs into the “MIC” jack on top of the Transmitter. The microphone should be positioned directly
in front of the tour guide's mouth to achieve an optimal signal to noise ratio and so that head move-
ment does not affect the loudness of the signal. The microphone cord acts as the transmitting anten-
na.
Optional Microphones
An optional Hearing Protector Headset Microphone (MIC 036) is also available for extremely high
noise environments. It features ear muffs that completely cover both ears and provides 24 dB noise
isolation for hearing protection.
An optional La
pel Clip Micr
ophone can be used in quieter en
vironments like museums or galleries.
T
he MIC 090 has an omnidirectional pick-up pattern. The MIC 056 has a directional (or cardioid)
pick-up pattern, which will reduce background noise.
A small hand-held microphone (MIC 026) is also available for tour guides who prefer to hold the
microphone.
THE TGS R30 RECEIVER
The TGS R30 Receiver is a battery-powered body-pack receiver used with a headphone to hear the
signal pr
oduced b
y the transmitter. The receiver is pre-tuned to the transmitter and has a user-
adjustable volume control. The headphone plugs into the “EAR” jack on top of the Receiver.
The receiver is turned on by rotating the volume control wheel. The TGS R30 Receiver operates
on two AA non-rechargeable alkaline batteries (BAT 001), or two AA rechargeable NiMH
batteries (BAT 026).
