consecutively one at a time, not simultaneously.

2. After pressing the Scroll Lock key, you have 2 seconds to press the Scroll Lock key again. You then have another
2 seconds to press a command key. A beep confirms that the KVM switch is in “hot key” mode. If you do not press a
key within 2 seconds, the switch will exit hot key mode.

3. (TK-423K only) If you have defined a different hot key preceding sequence key (e.g. Caps Lock, Esc, F12), press
that button instead of scroll lock. For example, if you want to turn on autoscan and have defined the hot key
preceding sequence key as F12, press F12 + F12 + S.
