Adjusting the Sync Interval - Instructions
If your P1 system appears to be operating correctly - you’re getting reliable triggering of slave flashes and you see the
flash adding light to your actual exposures, then you should not make any change to the Sync Interval.
The Sync Interval may be adjusted to a setting of between “1” and “10”. Your P1 Transmitter ships on a default setting
of “10” which works well with most hardware.
Starting Adjustment
Press and hold both Power Button and Link Button on your P1 Transmitter at the same time for approximately one
second until both Power LED and Link LED strobe together. Release Power Button and Link Button.
Current Interval Display
Your P1 Transmitter will indicate the current Sync Interval by blinking the Link LED in sets corresponding to the current
adjustment point. Sets of 4 blinks for example represent a Sync Interval adjustment of “4”. There is a clear pause
between sets of blinks. Count the blinks to determine the current adjustment.
Increment Adjustment
To increment the current setting, press the Link Button briefly. The Power LED will light during the button press and
the P1 Transmitter will increment its count. Each press of the Link Button will increment the count by one up to setting
“10”, then it will loop back to setting “1”.
Lock-In New Adjustment
Once the new setting is reached, lock it in by pressing the Power Button one time. The P1 Transmitter will confirm by
blinking both LED’s together a number of times corresponding to the new Sync Interval setting. The P1 Transmitter will
then resume normal operation.
Resuming Normal Operation
P1 Receivers are designed to find and lock onto any Sync Interval carrier signal - they require no adjustment after
changing this setting on your P1 Transmitter. They should automatically re-link to your P1 Transmitter.
Choosing a Setting
So which setting should you choose?? There’s a bit of trial and error involved. Again, “10” works great for most hard-
ware. You should sequentially increment the setting by 1 step at a time and test fire the system at each setting. You
should eventually find a setting that is reliable in triggering your slave flashes.
Suggested Settings
In our testing we’ve found setting “10” (which is the default setting) works with the greatest variety of hardware. A
few suggested alternates for Canon are 4 and 5, and Nikon setting 4 works well.
