LT-700 Troubleshooting continued
There is not sufficient range
The LT-700 is a portable transmitter that uses the microphone cable as an antenna and the range
will vary depending on the location of the receivers compared to the transmitter. You can only
expect about 100 feet of average effective working range.
It's confusing for users to have 57 channels when switching between
channels
Use the PROGRAM function to lock out unwanted channels. This way, users will only need to
scroll among a few channels.
I cannot change the channel
It is probably locked (check for the padlock icon). To unlock, press and hold the UP or DOWN
button for 5 seconds.
My batteries are not charging
Make sure you are using NiMH batteries and that the BATTERY SELECT switch (inside the bat-
tery compartment) is set to the NiMH position. Make sure the batteries are installed correctly.
Make sure you are using the right kind of wall transformer (Listen part number LA-202) or charg-
ing case. Make sure the charging case is connected to power and the unit is securely pushed into
its slot in the case.
NOTE: Listen uses 1800mAh (milli-Amp-hour) constant current NiMH (Nickel Metal Hydride)
batteries. These may be purchased from your Listen dealer (ask for part number LA-362).
