Stonex S10A GNSS Receiver – User Manual 58
Raccomandation for installing antennas for internal radios
An absence of specific alerts does not mean that there are no safety risks
involved in the use of this equipment.
Always follow the instructions that accompany a Warning or Caution,
reported in this. This information are intended to minimize the risk of
personal injury and/or damage to propriety. In particular, observe safety
instructions that are presented in the following form:
CAUTION
For your own safety, and to match the RF Exposure requirements of the FCC, always
observe these precautions:
- Always maintain a minimum separation distance of 20 cm (7.8 inches)
between yourself and the radiating antenna.
- Do not collocate (place within 20cm) the radio antenna with any other
transmitting device.
- Do not switch on the GSM or UHF module without the antenna mounted
to the external connector.
UHF Antennas having a gain greater than 5 dBi, are strictly prohibited for use
with this device. The required antenna impedance must be 50 ohms.
GSM/UMTS Antennas having a gain greater than 3 dBi (for mobile
applications) are strictly prohibited for use with this device.
To reduce potential radio interference to other users, the antenna type and
its gain should be so chosen that the equivalent isotropical radiated power
(e.i.r.p.) is not more than the one necessary to get successful connection.
