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.
