De-Link Sleep
When a carrier radio signal from a P1 Transmitter is found and locked onto, the Power LED and Link LED light solid on
the P1 Receiver. When the carrier signal is lost even very briefly, the Link LED will go dark as explained in the previous
section.
When the signal is lost, your P1 Receiver will search frantically in attempting to re-aquire it. It will keep this up for
about 20 seconds. It then begins to get bored and starts napping.
To conserve power, your P1 Receiver has been designed to enter a cycle of sleeping and waking when no carrier signal
from an active P1 Transmitter is found. At first the naps are brief - about 1/4 second. As time goes on and no signal is
found, these naps extend to a maximum duration of 3 seconds each.
During each “sleep” cycle, the Power LED will go dark, and upon each waking - your P1 Receiver will power up the radio
and sniff the air waves to see if a carrier signal exists from a P1 Transmitter. The Power LED will blink during the wake
cycle. If no carrier signal is found, the P1 Receiver goes back to sleep.
As soon as a signal is found and re-aquired, the Link LED is again lit, and loosing this signal will again cause the P1
Receiver to quickly search for it, and eventually resume a napping pattern.
This wake and nap pattern was designed to conserve battery power when no link exists. You may use this to setup a
Slave flash several hours before you actually need it and allow your P1 Receiver to essentially “stand by” without much
battery use. Some Slave flashes will also go into standby and will wake when seeing the signal from the P1 Receiver.
Please test on your own to see if your Slave flash is capable of awaking from standby when seeing a signal.
NOTE:
When attempting to turn off a napping P1 Receiver, the one second you press and hold the Power Button to
cause the power down will not begin until the next timed “wake” cycle of the P1 Receiver - when it is sleeping, it won’t
see your button press so you may need to hold the button longer than usual to power off the unit.
