3.1.2 STATUS LIGHTS
On the right-hand side of the display, three of the lights are used to indicate various status information on
the display. The status lights form a vertical row:
O Flywheel Light
O Synchronizing Light
O Event Light
The flywheel light goes on when the display loses its source of time. It indicates that the display is not
currently reading any time source, but is "coasting" with the last known time and rate. It may indicate a
noisy or disconnected input signal. Depending on the source of time, it may take up to six seconds after
the time code is lost for the flywheel light to come on.
The synchronizing light goes on when you have selected one of the synchronization options for the
internal clock. See Section 3.3.11, SET TIME (SHIFT-D) - Set Internal Clock. The light will be on
while the display acquires the time code or other time source. It will go off when the real time clock has
been synchronized to the time source.
The event light shows the status of the event capture input. When the event capture is disarmed, the
event light is off. When the event capture is armed, the light is green. It remains green until an event is
detected, when it turns red. You must clear the event to capture a new event (See Section 3.3.12 for
programming the event capture parameters).
3.1.3 PROGRAMMING
The display remains in Run mode, displaying time, until the PROGRAM key is pressed, which puts the
display in "Program" mode. In Program mode the operator can modify all the operating parameters.
The display remains in Program mode until the RUN key is pressed.
Most programming is done by selecting items from a list. You may select an item from the list in two
ways. First, you can use the SELECT key to advance through the list, one item at a time. Second, you
may press one of the number keys "1" through "9" to select items in the list. The "0" key is used to undo
any changes made since the last command.
There are some cases where the number keys are used as entries in text strings, so they do not select
items in the list. For example, when setting the internal clock, the keys 0-9 are used to enter the time
rather than select items in the list. These exceptions are noted on the following page.
