3. Non cellular antennas
3.1. Non cellular antenna description
• The phone has a pair of non cellular antennas mounted in the C cover of the device under a label.
• At the top of the phone near the power on/off key is a combined GPS/BT/WLAN antenna. This antenna has
1 feed pogo pin and 1 grounded pogo pin.
• Over most of the rest of the C cover there is an FMTx antenna which again has 1 connection pogo pin and
1 grounded pogo pin.
3.2. Non cellular antenna fault finding
• The NCW antennas are in the C cover. This should be inspected visually. Especially check the contact areas
(shown in the figure above) for dirt. Some denting of the contacts areas is expected and should not cause
a problem.
• Please refer to the RF section for fault finding information for the GPS, WLAN and BT systems.
