Antenna Description and Troubleshooting

CDMA Antenna on the E-Cover Assembly

The E-cover (or antenna cover assembly) is comprised of the E-cover plastic part, the
CDMA antenna (or CDMA radiator) and the bezel assembly. The bezel assembly includes
the camera, flash windows, and the bezel.
The E-cover connects to the D-cover assembly via six tabs located on the four corners
and top edge of the E-cover, as well as a snap-in feature located on the bottom two
corners.

Damaged CDMA Radiator Bezel Assembly

The CDMA flex radiator antenna and bezel assembly are glued to the inside surface of
the E-cover. To remove the E-cover assembly from the D-cover, use the SRT-6 opening
tool to release the two snap-in tabs that secure the E-cover to the D-cover.
If either the CDMA radiator or bezel assembly is damaged, replace the E-cover assembly.
Note: You cannot replace the CDMA radiator or the bezel individually. You must
replace the entire E-cover assembly.
To reattach the E-cover assembly to the D-cover, align the E-cover above the D-cover
and apply a vertical force to engage the snap-in feature.

Missing or Damaged CDMA Antenna and IHF Pogo Pins

The CDMA antenna is connected to the PWB through two pogo pins. The CDMA antenna
pogo pins are housed in the D-cover (see
If a CDMA antenna pogo pin is damaged or missing, replace the D-cover. An improper
connection between the CDMA antenna and the PWB due to a damaged or missing pogo
pin degrades the CDMA antenna performance by 5dB to more than 15dB.
