LR-300 Operation Instructions

1Make Sure the Unit is On

Rotate the volume knob counterclockwise with an earphone or headset connected to the unit. Listen receivers use the cable of the earphone or headset as a receiving antenna.

Be careful when turning the unit on - if you turn the knob too far you might get too much volume in your earphone!

2Test the audio

If a transmitter is broadcasting on that channel, you will be able to hear the audio. If the signal is too weak, the audio will be muted (squelched).

3

Find an audio transmission using SEEK

Another way to find a channel on the LR-300 is to use the SEEK button. When you do this, the Listen

 

 

receiver looks for the next active channel. Sometimes the unit will mistake interference for a real

 

broadcast signal. If you get interference, press the SEEK button again. The unit may stop on a

 

channel that is close to the actual broadcast channel, in which case the channel will sound noisy

 

or distorted. Simply press SEEK again until you find the clearest operating channel.

4 Adjust the volume control

Use the control dial on the top of the unit to adjust the volume to a comfortable level.

To Lock into Only One Channel

Press and hold the SEEK button for 5 seconds to lock a receiver onto the currently tuned

 

 

channel. Press and hold the button again to unlock. When locked the LED on top of the unit

 

will flash when you press the SEEK button.

 

IMPORTANT: Because the LR-300 has no LCD display, it is important to recognize when the unit

 

is locked on a channel. If the unit sounds distorted or there is no audio heard and

 

pressing the seek button does not correct the problem, the unit is probably locked

 

on the wrong channel. Press and hold the seek button for 5 seconds to unlock.

If locked, LED flashes on all portable receivers when SEEK button is pressed
