MFJ-462B MultiReader

Basic Operation:
The MFJ-462B MultiReader
TM
is easy to operate. The push-button marked POWER controls the power to the
unit. After turning the unit ON, the MFJ-462B will light the PWR LED and display a scrolling sign-on message
across the LCD. On the left side of the unit is a hole for LCD contrast adjustment. When the display shows the
SIGNAL SETUP prompt, the MFJ-462B is ready for operation. All the MFJ-462B requires for proper operation is
that you select the signal type that you wish to decode, the signal baud rate, along with tuning to the desired signal
on your radio. Some signals may require that you select the REVERSE function to properly decode the desired
signal. Once you properly tune your radio to the desired signal, the MFJ-462B begins to display the decoded signal
information. If characters cannot be decoded, which is the case for some RTTY signals, an underscore character
("_") will be scrolled for each undecoded character. If the unit is not decoding characters correctly, check the
format setting to confirm that it is correct.
Menu Operation:
The MFJ-462B menu system consists of two front panel push-buttons labeled OPTION and SELECT along with
the LCD display. Pressing the OPTION button changes the option being displayed on the LCD. The available
OPTIONS within the MFJ-462B operating system are shown below:
1. SIGNAL SETUP
2. BAUD RATE SETUP
3. PRINTER SETUP
4. RAM SETUP
5. REVERSE SETUP
6. PRACTICE KEY
Pressing the SELECT button executes the OPTION currently displayed on the LCD, and goes to a sub-menu.
Under each sub-menu are other selectable options. The options under the sub-menus are the actual mode settings,
such as OPERATING MODE, BAUD RATE, PRINTER ON/OFF, RAM PLAYBACK and RAM SCROLLING,
just to name a few.
For example, turn the unit ON, and wait a few seconds for the unit's sign-on message to finish. When the MFJ-
462B finishes its sign-on message, it displays the first main menu option, SIGNAL SETUP. Pressing the
OPTION button displays the second main menu option, BAUD RATE SETUP. Pressing the SELECT button
now causes the MFJ-462B to switch to the BAUD RATE SETUP sub-menu and display the first option, 45
BAUD. Pressing the SELECT button now tells the MFJ-462B to select 45 baud as it's decode baud rate, and to
return to the main menu option, BAUD RATE SETUP. Pressing the OPTION button repeatedly will cause the
unit to scroll through the next main menu options, PRINTER SETUP, RAM SETUP, REVERSE SETUP, and
PRACTICE KEY and then back to the first main menu option, SIGNAL SETUP. Pressing the SELECT button
now tells the MFJ-462B to switch to the SIGNAL SETUP sub-menu and display the first option, CW. Press the
OPTION button to switch the display to RTTY 170 and then press the SELECT button. The MFJ-462B is now
ready to decode 45 baud, 170 shift RTTY. Refer to Figure 1 for the MFJ-462B MultiReader™ menu layout.
