Looking after Voyager

LogIT Voyager SX is designed as an educational tool and although durable it requires a reasonable degree of care which any electronic product 
of this nature needs. Never plug anything into Voyager other than official LogIT Microsense

®

 sensors and accessories. Please read the warning 

guides throughout this book and in particular do not allow Voyager to get damp, wet or expose it to extremes of temperature or shock unless 
instructions specifically state. If the unit is accidentally exposed to any of these conditions it could malfunction and serious damage result. In the 
event of any problems remove the batteries immediately and seek advice. Always dispose of used batteries safely.

Safety and risk assessment

It is the responsibility of the user or teacher to have made suitable risk assessments before carrying out any student led experimentation.  A 
teacher has a duty of care towards their students to ensure experiments are carried out within a safe environment.  The instructions and 
experiment ideas contained within this manual highlight particular hazards but are not exhaustive and are not a substitute for your own 
assessment. Refer to your science departments risk assessment criteria and apply accordingly.
