WARNING
1. For 505U modules, a radio licence is not required in most countries, provided the module is
installed using the antenna and equipment configuration permitted. Check with your local
505U distributor for further information on regulations.
2. For 505U modules, operation is authorised by the radio frequency regulatory 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 outputs 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, serial cables and all terminals
of the 505U 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, serial cables and the module should be installed as recommended in the
Installation Guide.
4. The 505U module is not suitable for use in explosive environments without additional
protection.
