PR-500 Portable Receiver, Troubleshooting
The receiver has no power.
Make sure the unit has either fully charged
batteries or a Listen approved wall transformer
connected. Make sure the VOLUME knob has
been rotated to the ON position. If this does not
work, try a different set of batteries. Make sure the
batteries are installed properly.
There is no audio.
Make sure you have turned the volume control
up. Make sure the earphone is plugged all the
way into the jack on the top of the unit. Make sure
the transmitter is broadcasting an audio source.
Make sure you’re tuned to the same channel as
the transmitter. If the RF signal is too weak, the
receiver will squelch and mute the audio source;
move closer to the antenna or if using the LT-800
transmitter make sure the transmitter’s output RF
power switch is set on “FULL” (LT-800). Make sure
the squelch is not set too high (see page 17).
The audio is distorted.
Make sure you’re receiving on the correct
channel. Make sure the audio on the receiver is
not turned up too loud; this will cause distortion.
Make sure the earphone connector is pushed all
the way into the jack on top of the unit. Scan the
channels to find the clearest channel. Make sure
the SQ switch on your transmitter and receivers is
turned ON (or OFF, if some of your equipment is
not SQ capable). Make sure you are not too close
to the transmitter.
There is interference
.
Try different frequencies on the transmitter and
receivers until you find a clear channel.
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. Make sure the
squelch is not set too tightly (see page 17).
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.
Scan the channels to find the clearest channel by
pressing SEEK.
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.
I cannot change channels when pressing the UP
and DOWN buttons or the SEEK button.
The unit is locked. Press the SEEK button for 5
seconds to unlock.
My batteries are not charging.
Make sure the battery switch is in the NiMH
setting and that you are using NiMH (Nickel Metal
Hydride) batteries. Make sure you are using only a
Listen supplied charging unit or transformer. Never
try to charge alkaline or NICAD batteries.
I
want to run the unit from a wall transformer.
Plug a CSI approved transformer to the CHG/PWR
connector on the side of the unit. Batteries do not
need to be installed when operating the unit with
a wall transformer; however, if you have NiMH
batteries installed and the BATTERY select switch is
set to NiMH, the batteries will charge while the unit
is being used.
