options may include special modes for connecting to non- standard codecs.

and using the <YES (+)> and <NO (- )> buttons to raise or lower the number displayed.
Confirmation of the change is not required.

Changing the LCD backlight brightness is accomplished by choosing the item in the

Version Info
The final item on the UTILITY menu is a read- only display. The display contains
information you will need to provide Telos Customer Support should you call for
assistance.

installed. The first number is the system firmware, the second is the ISDN firmware, and
the third is the DSP and XILINX firmware.
The fourth line of the display has a date and code number. These refer to the firmware
and do not reflect the date of manufacture of your Zephyr.
Please have this information if you call Telos Systems customer support.
