Find an audio transmission using SEEK
Another way to find a channel on the LR-400 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 clear-
est operating channel.
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.
Is the Channel Locked on My Receiver?
On the LR-400, when the channel is locked, the padlock icon will appear on the display. If
the unit is locked, the red LED on the top of the
unit will flash when
you press the SEEK
button.
Padlock appears when locked
If locked, LED flashes on all
portable receivers when SEEK
