5. Select the desired operating frequency. Locate the “Channel Selector” inside the battery door (See FIG. 5). Use the supplied
small screwdriver to rotate the switch to the desired channel (See Channel Selection Chart, below).
6. Adjust the receiver tone control to your needs. Locate the tone control inside the battery door. Use the supplied small
screwdriver to rotate the “Tone Control”. A low setting (fully counter-clockwise “-”) emphasizes lower frequencies. A medium
setting (rotated to a vertical position) has some low frequency cut. A high setting (fully clockwise “+”) maximizes low frequency
cut and emphasizes higher frequencies.
Note: the earphone cord is also the receiving antenna. Do not bunch up the cord or wrap it around the receiver. For best
reception, the cord should hang as straight as possible.
7. Clip the receiver onto a belt or waistband, or slip it into a pocket (see Belt Clip Installation, page 8).
8. Check that the “FM Indicator” is illuminated yellow. Turn the “On/Off/FM Volume” knob to adjust the volume to a comfortable
listening level.
IMPORTANT: Make sure the receiver is turned OFF when not in use. Turn the “FM Volume” knob completely counter-
clockwise. It should “click” and the “Power On” indicator should turn off.
ADJUSTING THE R36 VOLUME CONTROLS:
A. Adjust the left control, “On/Off/FM Volume”, to a comfortable listening level. Check that the “FM Indicator” is illuminated
yellow. Turn the volume knob clockwise until you are able to hear audio from the transmitter.
B. Adjust the right control, “Mic”, volume second, turning it clockwise until you can hear sounds picked up by the plug mount
microphone.
C. Adjust the “Mic” and “On/Off/FM Volume” controls for a comfortable mix of FM and ambient sounds.
MAX GAIN CONTROL
Adjust the “Max Gain” if you have sensitive hearing due to hearing loss. This feature limits the maximum volume output by
the receiver in case of sudden bursts of sound. To adjust the “Max Gain”, use the supplied small screwdriver and turn it to a
comfortable maximum volume level. In a fully clockwise position the maximum volume is not reduced. In a fully counter-clockwise
position, the maximum volume is reduced by 17 to 20 dB.
LOW BATTERY INDICATOR
The “Power On” indicator (see FIG. 6/7, page 5) will flash to indicate low battery. The listener may continue to use until the unit
stops operating, then replace or recharge the batteries.
BATTERY INFORMATION
Open the battery compartment by pressing and lifting the tab on the back of the device with your finger. To remove depleted
batteries, pull up on the fabric strip. Press the new batteries into place over the fabric strip. Be sure to observe proper polarity
(+/-). Damage due to improper battery installation may void the warranty on the product. Close the battery door. The “Power On”
LED on top of the device will flash when the batteries are getting low; you may continue to use the unit until it stops operating,
then replace or recharge batteries.
The receiver or transmitter can use two (2) Alkaline AA batteries (BAT 001) or two (2) AA rechargeable batteries (BAT 026). Note:
The BAT 026 provides longer life than other rechargeable batteries. For best product performance, do not substitute other
rechargeable batteries and chargers.
CHANNEL SELECTION CHART
For convenience, the PFM T36, PFM R36, and
PFM R33 all use the same frequencies in the same
positions on their channel selection switches.
