This guide will provide some basic operational knowledge to allow
configuration of the COM-120B but you should consult the Operators
Guide for more detailed information.
Begin by selecting a test mode of operation. Press the
[REC] key now to enable the Transmitter Test screen.
Screen settings are accomplished by positioning a
cursor to a field label and establishing the desired
setting. The cursor can be moved to a different field
through use of the 4 arrow keys on the COM-120B's
front panel. These keys are located to the left of the
large knob in the DATA SCROLL section of the front
panel.
Changing Numeric fields:
To change the value of a numeric field such
as the RF frequency:
1. Position the cursor the field label (RF).
2. Use the numeric keypad to directly enter
the frequency and terminate entry by
pressing the [ENTER] key.
OR
3. Press the [ENTER] key to highlight the
frequency field.
4. Use the left or right arrow keys to position the cursor to the digit to be
changed and use the up and down arrows or the knob to adjust the
value of the selected digit. Terminate the entry with the [ENTER]
key.
Other Field types:
Another type of field allows selection of an item by list or menu. The
INPUT field (located just below the RF Frequency field) is an example of
this type. Position the cursor to the INPUT field and press the [ENTER]
key. With the field highlighted, press the up or down arrow key to cycle
through the available list of selections. Set this field to TR and terminate
the entry with the [ENTER] key.
