About safety
All Nautel transmitters are designed to meet the requirements of EN60215, Safety Requirements for
Radio Transmitters.
Radio Transmitters.
The philosophy of EN60215 is that the removal of any cover or panel that can only be opened using
a tool is a maintenance activity, and that any person performing a maintenance activity is expected to
be trained for that activity. Under EN60215, it is assumed that trained personnel will be
knowledgeable and will take precautions such as removing all power to the transmitter before
accessing its components.

WARNING: It is not enough to switch off RF power. The power line is
still connected. Disconnect and lock out the upstream supply before
servicing.
WARNING: Do not use an ordinary multimeter to check for voltage,
since it may have been left inadvertently on the AMP (A) range,
triggering a short and an arc blast that could result in severe burns
and even death.
