First Steps
You don’t want to be reading this.
Chances are, you reached for these pages because something isn’t working the way you
expect it to.
Cheer up. Most ZephyrExpress and ISDN problems are easily resolved, either by yourself
or with the help of the telephone company. Unless you see blue smoke pouring out of
the unit, these pages are probably all you’ll need to get running again. And if they aren’t
— or if you do see blue smoke — you can always contact Telos Customer Service at
• +1 216.241.7225 in the US (fax [phone])
• [phone] in Germany (fax [phone])
• [e-mail]
• [e-mail]

But try these pages first. It’s faster.

HOT TIP!
It may be that something isn’t working the way you expect it to, because it’s not
supposed to work that way. ISDN and audio coding is not as intuitive as tradi-
tional analog audio. If you’re not familiar with both of these new technologies,
read the first section of this manual before assuming something’s wrong.

ISDN TIP!
If ISDN won’t initialize —if you don’t see the word Ready twice on the screen —
and you’re absolutely sure the line is good and ZephyrExpress is programmed
properly, try these tricks. One of them will usually work.
• Unplug the telephone line from the back of ZephyrExpress, wait a minute or
two, and plug it in again.
• Change the ISDN: Switch type menu setting to the wrong kind of switch
and press EDIT to confirm. Wait a few seconds, change it back to the right
kind, and press EDIT again.
• Turn ZephyrExpress off, wait a few seconds, and turn it back on again. DO
NOT DO THIS BY DISCONNECTING THE XLR POWER CONNECTOR ON THE
BACK PANEL! This can damage the unit, or erase your settings. Use the
power supply’s switch, or disconnect it from the power line.
