A warning message is displayed and a beep will sound when
an alarm condition set by the user is met. Press
Esc
to clear
the alarm. However, the alarm will be displayed again when
the alarm condition reoccurs. the unit provides alarms for
various functions.
4-5-1 Fish
triggers an alarm when echo from the transducer is matched
to a preprogrammed fish profile.
4-5-2 Deep
triggers an alarm when the depth value received from the
transducer is deeper than a set value.
4-5-3 shallow
triggers an alarm when the depth value received from the
transducer is shallower than a set value.
4-5-4 temperature
triggers an alarm when the reported temperature from the
transducer is the same as a set value.
4-5-5 temperature rate
triggers an alarm when the rate of temperature change from
the transducer is the same as a set value.
4-5-6 low battery
triggers an alarm when battery voltage is lower than a
set value.
4-5-7 aIs
see the Alarm option of 4-4 (Ais settings).
4-5-8 restore default
returns every alarm setting to default.
4-6 Others
Press
mENu
then
others
.
4-6-1 simulate
simulate:
turn the simulate mode on or off.
4-6-2 GPs
GPs source:
select a source of GPs signals
static Navigation:
this option is very useful when the boat
stops or moves very slowly. this option allows you to set a
minimum speed at which movement is assumed. the value
range is from 0.00 to 9.99.
speed Filter and course Filter:
occasional waves and
wind at sea affect the boat speed and course. in order to
have a stable boat speed and course, the unit calculates
these factors to give the value of stable speed and course
information.
lat/lon d.p’s:
select the number of the last digit of lat/lon
to be sent to other marine electronics.
magnetic Variation:
this option compensates the
difference between true north and magnetic north.
4-6-3 units
select a unit of each measure.
tip:
requires optional sensors connected to unit for some
information to be available.
4-6-4 comms
use this feature when the unit is connected to other marine
electronics through any compatible nmEA instrument.
NmEa0183/NmEa2000:
this option is used to transmit
nmEA sentences to other marine electronics. nmEA0183
and nmEA2000 interfaces are generally used with third party
marine electronics. select a port (nmEA2000, nmEA0183-
Port 1 or nmEA0183-Port 2), a communication speed and
select desired output data.
4-6-5 calibrate
speed:
calibrate the boat speed. travel at a constant known
speed and press or to calibrate the speed.
speed filter:
set this option when removing
effects from waves and wind which affect the
speed of boat by averaging.
temperature:
calibrate the water
temperature. measure the water temperature
with a thermometer then press or to
calibrate the temperature.
temperature filter:
set this option to remove
the effects form water turbulence and currents
which cause the water temperature to
fluctuate slightly.
Keel offset:
A depth measured by a transducer is dependant
on where the transducer is installed. You can adjust the depth
of water taking into consideration as to where the transducer
is installed on the boat.
