Procedure C. Power-Up (cont'd)

Step

The system is factory-set to Auto Search for pilot channels on power up. Observe the

Lock display for each pilot. Any number other than 0 indicates the TimeSource 2700 has

detected, and locked onto, an acceptable pilot signal(s). Lock is required for only one pilot

for the system to produce PRS outputs. If Lock is not achieved within 30 min, move the

antenna to see if the system will detect an acceptable pilot signal.

Alternatively, do one of the following two options:

• Use a PCS CDMA phone with a signal strength indicator in the vicinity of the planned

shelf installation site. Choose the location in which to install the antenna by observing

the strongest signal strength on the phone. If the phone does not detect a signal, the

TimeSource 2700 should not be installed at that location.

• If the pilot signal channel for the PCS service provider is available, select the channel,

using the Select Pilot Signal Channel task in the Operation chapter. Selecting the correct

pilot signal channel allows the system to find and lock on the pilot signal(s) more quickly.
