4.3 Recommended Cable Length and Gauge
UL1571 32AWG HOOK UP WIRE OD=0.38mm, LENGTH=650mm (MAX.)
PS: This is the very minimum cable selection requirement. Performance could be more optimized if
cable length is shorter or premium cable is adopted.

from the LCD panel)
6. Solution for Thermal Red uction and Improving Antenna Gain
Adopting copper /aluminum foil or heat sink and then adhere it onto the top of combo module
shielding case. The bigger the foil/heat sink, the better the thermal conduction. Please note that

the size of foil/heat sink should just fit properly onto the shielding case. Foil/ heat sink size larger
than shielding area will impact the antenna performance. See below picture as a reference for
correct cutting size. Copper foil is highly recommended as it will enhance antenna performance.

9. Recommended The EMI Coating Ar ea
We suggest the area of EMI Coating must be within the length of Green line :100mm and the
width between blue line A and B (from the end of panel to end of A side). Don't Coating exceed
this area.
