■Emulation Options

This parameter allows the keyer timing to mimic that of other keyers, making the ÒfeelÓ more comfortable for operators used to different timing parameters.

The default is VØ.

To check or change the emulation, you must briefly use the Inquiry or Function mode. You will learn more about these modes beginning on page 35.

To check Emulation option:

1Press [CH 3]+[CH 4].

¥ The keyer will send Ò?Ó.

2Send a ÒVÓ.

¥The keyer will send the current emulation (e.g. VØ).

To change Emulation option: 1 Press [CH 1]+[CH 2].

¥The keyer will send ÒFÓ.

2Send a ÒVdÓ where d represents the emulation number (see table) that you desire.
