2.06.06 Generating Two-Tone Paging Signals

The COM3010 can also generate two tone sequential paging signals. Because there are two
tones involved, both displays are used with their corresponding function keys. It is important
to remember that each of the display fields is controlled by a specific function key. The 2nd
tone parameters are displayed in the RECEIVE display, and controlled by the corresponding
RECEIVE function keys

Modulation
Eight display fields are ALWAYS controlled by these corresponding function keys
In two-tone signal generation, the function keys are re-assigned to their nearest field rather
than the specific function that does not have it's own function key. The function keys associ-
ated with two-tone sequential paging are as follows:

and the kHz / mV key (Default level is factory set at 4 kHz). Your two-tone frequencies are
now setup.
