Resetting loop time<br />

A time code program loop plays from the first event time to the last event<br />

time, then resets and plays again. Any events with code times before the<br />

first time or after the last time are ignored. The resettable loop time can<br />

run from five seconds to 24 hours. 12<br />

If you are running a time code program from an external clock, the external<br />

clock will control the loop time with its own first event time and last event<br />

time settings. To provide synchronized internal clock backup, you must<br />

set the first event time and last event time in the Time Code Events<br />

display to correspond exactly with those times set for the external clock.<br />

Otherwise events might be missed until the two clocks synchronize. It<br />

takes at least 5 seconds for external and internal clocks to synchronize.<br />

Use this procedure to set loop times either when running on the internal<br />

clock alone or when running from an external clock with internal clock<br />

backup.<br />

Keystrokes:<br />

1. Press [S7] until [S8] reads<br />

Reset Loop.<br />

Actions:<br />

2. Press [S8], Reset Loop. Prompt reads:<br />

Enter first valid frame of internal<br />

time, then press ENTER. (Press<br />

TIME to edit specific fields)<br />

3. Press [1][0][0][0]. Sets ten seconds as the starting time<br />

for the time code program<br />

4. Press [Enter]. Prompt reads:<br />

Enter last valid frame of internal<br />

time, then press ENTER. (Press<br />

TIME to edit specific fields)<br />

5. Press [5][0][0][0][0] then<br />

press [Enter].<br />

Sets the time code program to reset at<br />

the five minute mark<br />

12.<br />

If the loop is set to less than five seconds, the internal clock resets it<br />

to five seconds from the loop’s starting time.<br />
