GPS Phoenix Interface

Run the GPS Quick Test in Phoenix to check the GPS BB.

The Flip Detect circuit uses a Hall-effect sensor to recognize the position of the flip

cover. The sensor has an open-collector output that is pulled low when a magnetic field

of sufficient strength is present at the sensor. The sensor is located on the Baseband

PWB, and the corresponding magnet is mounted in the mechanics of the flip. See

Figure 8

for the circuit diagram.

1. Check that the components are correctly mounted and soldered.

2. Check the voltage on VFLASH1. If not present, check the UEMCR IC.

3. Check that the input to KEYB1 on the UEMCR is low.

4. Check that the magnet is correctly located with respect to the sensor.
