3.1 Radio Frequency Hazard Information
The product described in this manual has been tested to comply with Maximum Permissible Exposure
(MPE) limits.
When operated with the supplied antenna and at maximum transmit power
1
, the antenna should not be
located within 20cm of where people may come in contact.
Antennas of this transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
3.2 OEM Handling Procedure
Static electricity can severely damage the 9256OEM. Handling of the OEM should be done with extreme
care and avoid any unnecessary contact with system components on the board. Always work on an antistatic
surface to avoid possible damage to the radio modem from static discharge. Always have the power supply
unplugged and powered off when inserting and removing connectors. STI Engineering assumes no
responsibility that results from failure to follow instructions or failure to observe safety precautions.
CAUTION
The 9256OEM is subject to damage by static electricity.
Always observe the handling procedures.
3.3 RFI-9256 Location
There are a number of rules to observe when installing the RFI-9256.
The radio should be placed away from computers, telephones, answering machines and other
similar equipment.
Long RS-232 cable runs (greater than 10 meters) should be avoided in areas with frequent lightning
activity or static electricity build-up. Nearby lightning strikes or elevated levels of static electricity
may lead to voltage spikes on the RS-232 circuits with potential failure of the interface. STI
Engineering supplies a range of external data interface converters for applications requiring long
cable runs.
