Telos ZephyrExpress user manual Control section, Edit knob

The SAFE indicator flashes briefly when changing codec modes.

If SAFE is blinking, it may mean that someone left ZephyrExpress in one of its loopback modes when they last turned the system off. Normal operation will be impossible until you use the Codec menu to turn Loopback: Off. Blinking is normal if you have a European ISDN card and aren’t connected to an ISDN circuit.

Edit knob

T Turn this knob clockwise or counterclockwise to cycle through selections in a menu, and through fields in the Dial screen. If you’re entering text or a number using the keypad, turn counter-clockwise to erase the current character and back up. If you’re entering text, turn clockwise to get to the next character.

The Edit knob encoder also includes a pressure-sensitive switch. If you press it towards the front panel, it works like a pushbutton.

Tap the knob momentarily to activate a menu item so you can make choices, to confirm a choice, or to exit a text or numeric entry.

Hold the knob in for three seconds to exit the current screen. Hold the knob in and turn it counter-clockwise one click to jump to the top of the menu. Hold it in and turn it a lot of clicks to get to the status screen quickly.

If the status display is showing, anything you do to the knob will bring up a Help screen. That’s because you can’t use the knob to edit any of the fields in the status display. If Help appears, you may tap the knob again to return to the status screen.

The knob generates a clicking sound when you turn or press it. You can adjust click volume in the System menu.
