WARNING!

ZephyrExpress units sold in North America provide power for an external NT1. If
you’re using one of these, disconnect any other power supply connec-
ted to the NT1. If both ZephyrExpress and the NT1 are providing power, both
will be damaged.

You can tell if a ZephyrExpress will supply power by looking at the ISDN
connections: if there are two telephone jacks, it’s a North American unit and
you must follow the above precaution. If there’s only one telephone jack, it’s a
European unit and can be connected safely to powered NT1s.

European units are also marked with this Euro Telecom logo on the rear panel.

If you’re using a North American ZephyrExpress with two telephone jacks, and a
European or Asian NT1, disconnect the NT1’s power supply! Once you have
done this, you may connect an eight-conductor cable to the NT1. If you can’t
disconnect the NT1’s power supply, contact Telos Customer Service before
proceeding.

3. If you’re using a European ZephyrExpress in North America, you’ll need an

external NT1. It’s about the size of a small book, has some telephone-type
connectors, and usually has some little indicator lights. You’ll need two cables:
The first is a large, telephone-type modular cable with eight wires that fits into
the single jack on the Zephyr and a jack on the NT1 that is labeled “Terminal.”
The second is a telephone-type modular cable that fits into the jack on the NT1
that is labeled “Line” and the jack provided by the telephone company.

If you’re using this kind of NT1, you may connect the two telephone cables now.

The external NT1 has its own power supply. Do not use the external NT1’s
power supply if your ZephyrExpress has two telephone jacks on the back.
If
your ZephyrExpress has only one telephone jack, you may connect the NT1’s
power supply now.

· You’ll also need a microphone, a mic cable with an XLR male plug, and a stereo

headphone with a standard 1/4” tip/ring/sleeve plug.
