Description This softkey (Option 002 only) activates the frequency modulation mode for an external source. The FM source is connected to the FM modulation connector. The FM sensitivity function is active. It is factory preset to 10 MHz/V. Use the numeric entry keys, arrow keys, or rotary knob to change the sensitivity to 100 kHz/V or 1 MHz/V.

When external FM is in effect, the RF output is frequency modulated with a rate and depth set by the external source. The FM coupling is controlled by the following softkeys: FM Coupling 1OOkHz

FM Coupling DC!. The FM coupling defaults to 100 kHz. This is AC coupling for FM rates of 100 kHz or greater. For modulation rates below 100 kHz, choose DC-coupled FM.

An asterisk next to the key label indicates that external FM is active and FM is displayed on the message line.

For synthesizers without Option 002, see FM an/Off AC and

FM an/off DC.
