PIX-200 ATOMIC CLOCK/Time code signal reception duration
The target duration of PIX-200 to receive time code signals is as follow.
When the radio wave condition is good, it will take about 3 minutes
until it completes time synchronization.
At the automatic reception every night (from 1:15am to 4:00am), it
may take up to 166 minutes to complete time synchronization
depending on the radio wave condition.
When the radio wave condition is bad,
1) At the automatic reception every night, it will discontinue the
reception when it passes 166 minutes (4:00am)
2) At the automatic reception when you plug in the unit, it will
discontinue the reception after 15 minutes.
3) When you manually start reception, it will continue to search for
time code signals forever.
(Please refer to page 18 of the operation manual to see how to
start reception manually.)
