General
IMPORTANT
All possible measures must be taken to ensure water, fluid or dust does not
contaminate the internal components of the unit whilst unpacking, preparing and
installing it in inclement weather conditions or by negligence.
Do not drill any additional holes in the casing. Make sure any unused cable
entry or mounting holes are properly sealed against water or dust ingress.
Failure to do so may result in an unsafe condition and will invalidate your
warranty.

Site requirements
Ensure that the following are available before installation:
1. Survey the proposed site for GSM signal strength. Using an appropriate testing
device, establish that there is sufficient signal strength at the proposed location for
the network provider being proposed. Note that GSM performance can vary widely
between different providers' networks and can be affected by building structures.
Occasionally there can be "dead spots" where signal is low, but may be adequate a
short distance away. If signal strength is too low it may be necessary to either re-site
the unit, choose a different provider or site the aerial remotely (see below).
