Updates

How ZephyrExpress works is almost entirely determined by software. This booklet is based on software version 1.2.1.

Power Supply

e

ZephyrExpress is powered by a separate modular power supply, which is self- adjusting to any voltage between 100 - 250 VAC, 50 - 60 Hz. It connects to a 4-pin XLR connector on the rear panel. The supply must be turned off at its switch, or disconnected from the AC line, before plugging or unplugging this XLR connector.

WARNING:

Do not use the XLR connector as an on/off switch!

Connecting or disconnecting the power supply while it is powered can erase current ISDN setup and other user settings.
