Telos ZephyrExpress - Manual (Page 19)

QUICK RESULTS 1-7
Configure ZephyrExpress for your ISDN line.
h
HOT TIP!
There are two boxes on the bottom of ZephyrExpress’ screen.
If you see the word Ready in both of them, your unit is probably already
configured for the ISDN line. Skip this step, and go right to “Calling Yourself” on
page 1-9.
If you see the word inact in both of them, your unit is not connected to a
working ISDN circuit. Recheck your connections.

ISDN TIP!
You can check ISDN continuity with an ordinary analog telephone or a pair of
600Ω headphones. Disconnect ZephyrExpress, and briefly place the phone (or
phones) across the line. You should hear either a rhythmic clicking — about
once per second — or a loud, continuous white noise. If you hear a dial tone, it’s
not an ISDN circuit. If you don’t hear anything, the line is dead.
ZephyrExpress is configured by pressing the UTIL button, using the EDIT knob to select
menu items, and tapping the EDIT knob in towards the panel to confirm choices. The
process is intuitive, and you should be able to configure your unit with a minimum of
instructions. But if you get lost, see the instructions on page 1-16.
To configure ZephyrExpress for a particular line, first make sure you have the
information about that line from page 1-4.
u
Press the UTIL button.
The LCD display will change
to look like this:
Lost already?
If you don’t see something that says Utility Screen at the top, don’t panic. Just turn the
EDIT knob counterclockwise until it appears.
If the second line of the screen says something other than System Defaults , don’t worry.
If you don’t see anything at all on the screen, but you know ZephyrExpress is getting
power (because some LEDs are on):
If the screen is dark, press the DROP button and hold it in while turning the EDIT
knob clockwise to reset the backlighting. This may take a few turns.
If the screen is lit, press the DIAL button and hold it in while turning the EDIT knob
either direction to chance the LCD contrast.
