Problem Solving Checklist
52
If the mobile station does not find service, does not register, or does not connect
when a number is dialed on it, check the following items:
Is the RF cable connected?
Is the RF Channel number correct? (Set the RF Channel on the CDMA Call Control
screen.)
Is Sector A Power adequate? If interference from other cellular band signals is present,
Sector A Power may need to be set to a level greater than the instrument's preset value
of −75 dBm/BW. (Set Sector A Power on the CDMA Call Control screen.) Example: If
the mobile station is finding analog service, adjust Sector A Power to −30 dBm/BW,
then cycle power on the mobile station. Isolating the mobile station may be necessary.
Is the AWGN generator (CDMA Gen Control screen) off?
Is the mobile station programmed to roam? If not, set the System ID on the CDMA Cell
Site Configuration screen, then cycle power on the phone.
Are the entries in the Rgstr SID and Rgstr NID fields valid entries for the mobile
station? (The Rgstr SID and Rgstr NID field entries, found on the CDMA Cell Site
Configuration screen, must be recognized as a valid SID/NID pair by the mobile
station).
Are the entries in the Rgstr SID and Rgstr NID fields different than the mobile station's
Home SID/NID? (The Rgstr SID and Rgstr NID fields, found on the CDMA Cell Site
Configuration screen, must be different than the mobile station's Home SID/NID).
Is the power supply providing adequate current? (Make sure the mobile station's power
supply duplicates the voltage, impedance, and ampere hours of the manufacturer's
recommended power supply).
