8.3.3 IC Caution
WARNING:
Changes or modifications made to this equipment not expressly approved by Telit may void
the IC authorization to operate this equipment.
8.3.4 IC RF-exposure Statement
This equipment is portable device. According to RSS-102 Issue 5 §2.5.1 Exemption Limits
for Routine Evaluation – SAR Evaluation Table 1, the allowed distances to the human body
for products implementing the BlueMod+S42 can be calculated as follows. If the intended use
of the end product asks for smaller distances a SAR evaluation has to be made with the end
product.
• Max. RF output power: Occurs at -40°C at 2402MHz to 2480MHz with +6dBm
• Antenna peak Gain is +2dBi
• Resulting max. RF output power is +8dBm = 6,3mW < 7mW
• Table 1 shows that for 2450MHz the distance at 7mW should be ≥ 10mm
8.3.5 IC Labeling Requirements for the End Product
Any end product integrating the BlueMod+S42/AI must be labeled with at least the following
information:
This device contains transmitter with
FCC ID: RFRMS42
IC-ID: 4957A-MS42
8.3.6 IC Label Information BlueMod+S42
The BlueMod+S42 shows IC-ID on the product label,
Model: BlueMod+S42
The IC-ID is: IC. 4957A-MS42
