C.) CHANGING MENU ITEMS:
To change a function or value, select the menu containing the item to change using the “UP”, “DOWN”, “RIGHT”,
and “LEFT” buttons. After selecting the correct menu, press the “RIGHT” button to change a menu item. If part
or all of the bottom row starts flashing, you can change that item.
If the entire bottom row flashes (most items), press the “UP” or “DOWN” button to change it. These buttons have
auto-repeat. For tuning or channel ID (NAME) values, only one character in the bottom row will flash. The
“LEFT” and “RIGHT” buttons select the position to change and the “UP” and “DOWN” buttons change the
value.
When you are through with the change (or if there is no change), pressing the “ENTER” button will enable the
displayed parameter or value, the change mode is exited, and the display will stop flashing. If you do not press the
“ENTER” key, the parameter will return to the original value after a time-out of about 15 seconds.
3) SOME MENU-SPECIFIC INFORMATION
A.) Display of NAME and TUNING:
This is the normal (default) display and is the menu shown as the top left menu on page 5 of this manual. You can
not make any change from this menu. The NAME is programmable from the NAME menu and the tuning is
programmable from the TUNING menu. The display will return to this default after about 30 seconds of button
inactivity
If the programmed TUNING MODE is CHAN, the display will be the channel number. If the programmed
TUNING MODE is FREQ, the display will be the frequency in MHz.
Note that if the TUNING MODE is changed from CHAN to FREQ, the LCD will display the frequency of the
previously-selected channel.
B.) IF INPUT:
This indicates the preferred choice of the normal IF source. A rear panel input or an automatic transfer could
switch to the AUX IF input.
C.) CHANNEL PLAN:
The CHANNEL PLAN determines the OTM-4870 output frequency for a selected channel number. Tables at the
end of this manual list these values.
Note that FCC offsets are automatically provided for the STD and EIA channel plans and that an offset is applied
to all channels in the IRC plan. The HRC channel plan provides no offsets.
D.) NAME:
This menu allows you to program the NAME that appears at the top of the normal (default) display. Upper case
and lower case letters as well as numbers and various symbols are available for use.
E.) COMMAND MODE, BAUD RATE, and ADDRESS:
These functions are not used with the OTM-4870.
