Step 1.
Battery Installation:
Open the battery compartment by using a coin in the coin slot in the bottom of the receiver. Press
the battery into place, observing proper battery polarity.
Step 2.
Plug the earphone or headphone into the earphone jack.
Step 3.
Turn the receiver on by rotating the volume control in the direction of the arrow on top of
the case. Turning the knob in the direction of the arrow will increase the volume. Turning the knob
against the arrow will decrease the volume. To avoid draining the battery, make sure the receiver is
turned off when not in use.
Step 4.
If you are using the T21 with an existing sound system, make sure the sound system is turned
on. Have someone speak into a microphone while you listen with the receiver and earphone. You
should be able to hear their voice through the receiver.
If you are using the T21 with a microphone, have someone speak into the microphone while you
listen with the receiver and earphone. You should be able to hear their voice through the receiver.
Step 5.
The T21 Transmitter has a screwdriver-adjust input level control located on the front panel to
compensate for different input signal levels. Adjust the control so the “OK” audio light flashes with
the signal. It is alright if the “HI” light comes on occasionally. Reduce the signal level by turning the
control counter-clockwise if the “HI” light is on all the time.
If the “OK” light does not come on at all, turn the T21 input level control clockwise to increase the
signal. If the input level control is fully clockwise and the “OK” light still does not come on, you will
need to increase the signal level at its source (mixer or P.A. amplifier). The phone jack monitors the
sound exactly as it is transmitted.
Additional Instructions for Receiver Model PPA R7-4, PPA R7-6:
The R7-4 and R7-6 receivers feature a channel selector knob on top of the receiver. Turn the
selector knob until you hear the desired program.
Additional Instructions for Receiver Model R16:
The R16 Receiver features a microphone input and dual volume controls. The taller knob turns the
receiver on and off and controls the FM signal level. The shorter knob controls the microphone
signal level. By adjusting the two volume controls, you can hear a mixture of the FM signal and
nearby sounds picked up by the microphone. For more information, see the instructions included
with the R16.

Step 1.
Plug the R700 power cord into a 120 VAC, 60 Hz electrical outlet.
Step 2.
Attach the antenna to the connector on the rear panel of the R700.
Step 3.
Turn power switch on and adjust volume control until you hear the signal from transmitter.
Using An External Antenna with the R700:
The optional ANT 005 Coaxial Antenna may be used with the R700 to extend the reception range.
Using An External Speaker with the R700:
An external loudspeaker may be used with the R700. Connect the + (plus) loudspeaker wire to the
tip connection of a 1/4" mono phone plug. Connect the - (minus) loudspeaker wire to the sleeve
