Preface 

Using this guide 

This guide assumes, the user has basic computer skills and is familiar with the Windows Graphical User Interface 
(GUI) and GNSS receiver environments. 
The following symbols are used in the document to highlight information: 
 

 

A warning symbol indicates actions that could negatively impact or damage the device. 

 

An index finger points out key information pertaining to device operation and performance. 

 

Warnings and certifications 

 

      EVK-M8QSAM is an Electrostatic Sensitive Device (ESD). 
 

 
 

 

CAUTION!  RISK  OF  SHORT  CIRCUIT  OF  THE  BATTERY

 

WHEN  TOUCHING  IT  WITH 

CONDUCTING  PARTS.  IN  THE  UNLIKELY  EVENT  OF  A  FAILURE  IN  THE  INTERNAL 
PROTECTION  CIRCUITRY  THERE  IS  A  RISK  OF  AN  EXPLOSION  WHEN  CHARGING 
FULLY  OR  PARTIALLY  DISCHARGED  BATTERIES.  REPLACE  THE  BATTERY  IF  IT  NO 
LONGER HAS SUFFICIENT CHARGE FOR UNIT OPERATION. CONTROL THE BATTERY 
BEFORE  USING  IF  THE  DEVICE  HAS  NOT  BEEN  OPERATED  FOR  AN  EXTENDED 
PERIOD OF TIME. 

 

 

Products  marked  with  this  lead-free  symbol  on  the  product  label  comply  with  the 
“Directive  2002/95/EC  and  Directive  2011/65/EU  of  the  European  Parliament  and  the 
Council  on  the  Restriction  of  Use  of  certain  Hazardous  Substances  in  Electrical  and 
Electronic Equipment” (RoHS). 
EVK-M8QSAM evaluation kit is RoHS compliant and green (no halogens).
