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 reenter 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 Menu2. 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.

2A 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.
