LT-700 Portable Transmitter Programming
LT-700 Programming
In General: The LT-700 can be programmed to transmit on a limited
number of channels. For applications where users are required to
select a channel (such as classrooms), and you don't want them to
have to scroll through all of the available channels, this feature is ideal.
If all channels where available, the user could have 57 channels to
select from.
