WARNING
1.
In some countries, a radio licence is not required for the 805U telemetry
modules provided the module is installed using the antenna and
equipment configuration prescribed.
2.
Where a radio licence is not required, operation is authorised by the
relevant Authority in your country on a non-protection basis. Although
all care is taken in the design of these units, there is no responsibility
taken for sources of external interference. Some delay in the operation
of the module may occur during periods of interference. Systems should
be designed to be tolerant of these delays.
3.
To avoid the risk of electrocution, the antenna, antenna cable, and all
terminals of the 805U module should be electrically protected. To
provide maximum surge and lightning protection, the module should be
connected to a suitable earth and the antenna, antenna cable, and the
module should be installed as recommended in the Installation Guide.
4.
To avoid accidents during maintenance or adjustment of remotely
controlled equipment, all equipment should be first disconnected from
the 805U module during these adjustments. Equipment should carry
clear markings to indicate remote or automatic operation. eg. "This
equipment is remotely controlled and may start without warning. Isolate
at the switchboard before attempting adjustments."
5.
The 805U module is not suitable for use in explosive environments
without additional protection.
