Receiver Troubleshooting
Receiver Troubleshooting continued
I cannot pick up the signal on the receiver.
Check to make sure the receiver and the transmitter are on the same frequency and channel. Also
make sure the receiver is in broadcast range of the transmitter.
I can pick up the signal on the receiver, but it sounds like it’s not tuned in.
Check to make sure the transmitter and receiver are on exactly the same channel number/letter. If
you’re using the LR-300, re-scan the channels to find the clearest channel by pressing SEEK (see
page 50).
I’m using another brand of transmitter - how do I tell which channel to
use?
Refer to Listen’s Frequency Compatibility Tables (pages 60-63). Either adjust the transmitter or the
receiver to a common channel.
There is not sufficient range.
Make sure you are located as close as possible to the antenna of the transmitter. Try to place the
antenna as high as possible and free from obstacles. You can also check the squelch setting; perhaps
it is too sensitive. To change this setting, refer page 17 (LR-500) or to page 36 (LR-400).
Users keep changing channels.
You can prevent users from changing channels by locking in the channel selection. This is done by
pressing and holding the SEEK button for 5 seconds. When the channel is locked, the padlock
icon will appear on the LR-400 and LR-500 displays. On the LR-300, the LED will flash when the
channel is locked and seek is pressed. In addition, you can lock the access doors to the units.
