UIM Card Flap Grounding
The UIM card flap must be grounded to the RF shield with a conductive sticker.
Disassembling the RF shield from the chassis damages the sticker. You must remove the
sticker to change the antenna module or the UIM card flap. If the sticker is damaged or
missing, then the radiated sensitivity at maximum power could be reduced by 1-2 dB.
• If the conductive sticker is missing or ripped, replace it.
• If the RF shield is replaced, install new labels (type labels) and a new conductive
sticker. If the conductive sticker is located underneath other labels, then it may
be necessary to replace all other labels as well.
