The system must be installed by skilled personnel using calibrated HF test instruments.
The radiated HF power must be kept below the defined maximum radiation power for
Ocean Radar of 50 W
ERIP
(47 dBm). Please note that the WERA power amplifier is
capable to provide up to 49 dBm to compensate for cable losses for cases with the Tx
antenna system installed in a distance of several 100 Meters.
PA output level = max radiation
– antenna gain + cable loss
If the radiation can’t be measured in the field, the antenna gain should be assumed as
best case which is 6 dB. The output power can be set in steps of 2 dB and must always
be adjusted to be below the permitted radiation level.
The WERA system may only be operated in rooms with an electrical installation
complying with the regulations for the use of outdoor equipment.
The WERA system is only to be maintained or repaired by appropriately qualified
personnel.
Any modification
of the system which is not explicitly defined in the user
manual
will void the authorisation to operate the system
.
This equipment has been tested and found to comply with the limits as defined for a
Class “A” device in part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications.
Operation of this
equipment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own expense
.
Caution
: Never use the WERA system without training or reading these instructions.
