If the frequency (from Step 1) is > 431 MHz, then the
alignment frequency = 431 MHz.
If the frequency (from Step 1) is < 405 MHz, then the
alignment frequency = 405 MHz.
Otherwise, use the actual frequency from Step 1.
Step 3. If Receiver Module is Range 2, determine the
alignment frequency as follows:
If the frequency (from Step 1) is > 468 MHz, then the
alignment frequency = 468 MHz.
If the frequency (from Step 1) is < 440 MHz, then the
alignment frequency = 440 MHz.
Otherwise, use the actual frequency from Step 1.
Step 4. If the Receiver Module is Range 3 or 4, determine the
alignment frequency as follows:
If the frequency (from Step 1) is > 518 MHz, then the
alignment frequency = 518 MHz.
If the frequency (from Step 1) is < 472 MHz, then the
alignment frequency = 472 MHz.
Otherwise, use the actual frequency from Step 1.
For stations with multiple receive frequencies, calculate the
frequencies of the alignment signal as follows:
Step 1. From the site documentation, or the RSS, note the
receive frequency for each channel supported by the
station.
Step 2. Calculate a midpoint frequency as follows:
F = (F
mid
Step 3. Using F
mid
perform Step 1 through Step 4 above.
Step 1. Make sure the Receiver Module (with the Preselector
Assembly) is installed in a functional PDR 3500.
