reset the GE, increment the “Code Download Failure” PPC, and try to download the code 
again. After the third unsuccessful attempt of download, the CE will declare a hardware 
failure and hold the GE in reset. If download is successful, it will configure the GE and 
then put the GE to sleep. Sleep is the normal state of the GE and the only time it is 
woken up is from any of the following:
To perform periodic self-test
When an IS-801.1 location session starts
When a command is sent to it through the test interface in the Location 
Server SW in the CE, (e.g., a command from Phoenix)
During sleep of the GE, the RF regulator is off and the RF ASIC is powered down. The 
baseband ASIC remains powered on, but has no internal clocks running except the sleep 
clock from the CE.
Additional information on GPS can be found in the Troubleshooting - GPS chapter of this 
manual.
