Test pages allow the user to initiate a number of useful routines, for example
Test. When a Test page is displayed, pressing the
Select button starts the test
routine.
Closing the Menu
There are two ways to close the menu and return to normal operation. The
easiest way is to wait 5 seconds for the unit to time-out and revert to the
standard display. Alternatively, use the
Step button to page forward until the
display shows End and then press the
Select button once.
If the unit times out before the operation in hand has been completed, simply re-
enter the menu, page forward (or backward) and continue where you left off. If
you find the 5 second time-out difficult to use, you can extend it by changing the
TimeOut setting.
Menu Sequence
Use the flow chart (Figure 4) or the Control Summary sheet to guide you
through the Menu more quickly.
The following explanation deals with the Menu pages in the sequence they
occur in the Menu

. The use of each page is shown on an individual basis, with
the last operation being closing the Menu. After you have become more familiar
with the Menu, you will find it more convenient to perform all the Menu
operations in one go before finally closing the Menu.

Couple – Setting the format of the Ext Ref Input
When the External Reference Input is in use, the input characteristics must be
set to match the source. There are two options:
TTL The input accepts a DC coupled clock at TTL
levels. This is the usual setting for Word Clock
references.
Bipolar The input accepts a DC or AC coupled clock,
which has an even voltage swing about ground.
This is the usual setting for GPS references.
do this: Open the Menu and step through until the display shows Couple.
do this: Press the
Select button to flip between TTL and Bipolar.
do this: When you have the option you want, wait for the Menu to time-out and the
display to revert to its normal mode.
IMPORTANT! The Ext Ref Input will not operate if this menu is set to TTL and an AC
coupled cable used.

A minor software update may change the order of the menu items or add an option. If this happens, the
Control Summary sheet may be updated before the manual.
