6.6.3.2 Range Mode
Within the Range mode menu, the transceiver instrument range can be selected between 24 and
48nm.
24nm: Limits the transceiver to an instrumented range of 24nm. This offers twice the range
discrimination of the 48nm range.
48nm: Limits the transceiver to an instrumented range of 48nm.
6.6.3.3 TX Power
The output power of the SharpEye
TM
transceiver can be switched between High (default) and Low.
High power: The SharpEye
TM
transceiver transmits at full power.
This is the recommended default setting.
Low power: Low power is used in close waters or in a high clutter environment where a high
output power may produce excessive unwanted reflections from buildings, bridges
and vessels.
The transceiver will utilise the standard frame pattern but with output power reduced
to less than 40W.
Caution: As a result of reduced output power, range performance will be reduced
and the system may not meet the expected operational detection performance.
When low power is selected, a low power status is automatically generated to advise
the operator that the system is operating at a reduced output power.
Where the SharpEye
TM
detects a VSWR or a high temperature within the transceiver
the system automatically switches to low power mode and generates system alarms.
