The Select button is used to change the channel. Press the button once to change the channel. The
unit will either seek or scroll through the channels depending upon which channel selection method you
have enabled. See below for description of possible channel selection methods.
Select a Channel and/or Program Channel Selection Method
5A
When set to factory defaults the unit will turn on to the last channel is was tuned to upon
power up. However, the unit can be programmed to continuously seek for a channel with
signal upon power up until one is found (Auto-Seek). See page 102 for more programming
information.
Upon Power up
5B
If you know what channel the unit will be used on, and you know that there is only one
channel that the unit will need to be used on, you can lock it onto that channel now.
See page 101 for channel lock information.
Single Channel Systems
5C
In systems that require the receivers to be able to access more than one channel you
must decide which type of channel selection method you want enabled. The default
setting is that each time you press the Select button the unit will scroll to the next
channel. If you want the receiver to automatically begin seeking for another channel
when the signal is lost (such as walking from room to room in a museum) the Auto-Seek
function must be enabled. See page 102 for more information.
Multiple Channel Systems

If the receiver will be receiving a mono signal (stereo mode is not enabled on LT-82) no action is required as
Mono Mode is the default setting. However, if the receiver will be receiving a stereo signal the receiver must be
set to Stereo Mode to function properly.
Select Stereo/Mono Mode

Additional programming options, in addition to the Auto-Seek and Stereo/Mono Mode functions described
above, are the Channel Lock-out and Squelch setting. See page 102 for a complete explanation of the
programming functions for the receiver.
