Preliminary RF Troubleshooting

Verify the following if the mobile terminal cannot make a call:
• The mobile terminal is in Normal or Test Mode (i.e., the mobile terminal is
searching for a signal, net server is on).
• The Preferred Roaming List (PRL) is loaded into the mobile terminal (for Normal
mode).
• The mobile terminal is tuned and has passed tuning. Read the tuning parameters
using the Read Parameters component in Phoenix. An untuned mobile terminal
has all zeros in the tuning file.
