LCD Panel Operation

This chapter explains how to place and receive calls using the U-
336S front panel. An introduction to the panel operation of your
modem is presented. Your modem comes with a menu driven 20 x
2 LCD display. All functions of the modem are displayed and
selectable from this menu. Finally, this chapter will familiarize the
user with the menu tree structure which categorizes modem
operations for easy and quick reference. Modem users can also use
the panel menu operations and use the equivalent AT commands
listed in this chapter.
If you use your modem with a PC the factory default settings
should be just right for you. Connect the modem according to the
instructions in Chapter 2, install the communication software,
follow the instructions in this chapter, and you're all set!

The modem's actions, options, and parameters can be set, changed,
and viewed from the front panel, or viewed and changed through
AT commands by the computer or terminal connected to the
modem. We will discuss panel operations in this chapter with
reference to equivalent AT commands. Note that in most cases you
will use your communication software to send AT commands to
your modem. Only in very rare circumstances will it be necessary to
use the modem's panel.
Once turned on, the modem goes into the Idle Screen state (except
if a leased line is selected). It then waits for commands from a
