4 Power on the GPS clock module by setting CB 15 to the ON (up) position.
The GPS clock module will perform its internal diagnostics and begin to acquire
and track satellites. It may take up to 30 min for the GPS receivers to acquire a
rough position and time. The accuracy of the receivers improves as the satellites
are tracked.
See AccuSync-R GPS Synchronized Time and Frequency Instrument User’s
Manual (377-8006), available from Zyfer Inc., for information about the GPS clock
module.
5 Power on each RFSS module in the RF rack separately. Table 5.2 shows the
circuit breakers for the RFSS modules.
