When operated in the presence of high EM fields, interference in the form of additional measurement noise may be experienced. This is no cause for concern but the user should endeavour to minimise any adverse effects so caused through careful positioning when in use and/or not operating within close proximity of potential sources of interference such as mobile telephone transmitters, antenna masts, etc.
