CONNECTING EARPHONES

Plug an earphone into the “Ear” jack on the top of the R19 receiver. Only monophonic earphones will

operate properly. If stereo headphones are used, sound will be heard only in one side. A suitable adapter

(Radio Shack Part #274-368) can be used so that stereo earphones operate on both sides

OPERATING THE RECEIVER

NOTE: If you’re using the PPA T35 transmitter, make sure the transmitter is on and receiving a good

audio source. Also, make sure the T35 is operating in Narrowband mode, and transmitting on the same

frequency as the receiver (72.900 MHz or 75.700 MHz).

Turn the receiver on by rotating the volume control knob clockwise. A green power LED indicator will

illuminate. If the power indicator does not illuminate, go back and make sure the batteries are properly

installed. If you are using rechargeable batteries, you may need to charge the batteries overnight before

operating the receiver.

Choose an operating frequency by sliding the channel selection switch to position 1 (72.900 MHz) or

position 2 (75.700 MHz).

Turn the volume control knob clockwise until the audio is at a comfortable listening level. Adjust the

tone controls as needed by sliding the tone selection switch to low, mid, or high. When you’re done

using the receiver, be sure to turn off the unit. This will help extend the life of the batteries.
