Humminbird 200DX - Manual (Page 30)

USING THE 200DX USING THE 200DX
MENU FUNCTIONS
Once the Fish Alarm is enabled, the 200DX emits an
audible beep when the selected size fish symbol
appears on-screen. The sound is slightly different for
each of the three fish symbol sizes, so with practice,
it is possible to distinguish the size of the detected fish without looking at the unit.
Triplog. Triplog provides a running log or information based
on input from the Temp/Speed sensor.
Since Triplog requires information from the
Temp/Speed sensor to operate, if this sensor is not
detected by the 200DX, the Triplog menu will not appear
as an option.
Triplog provides seven pieces of information: the current
digital depth, water surface temperature, current boat
speed, the distance traveled since the 200DX was powered
up or reset, the average speed, the total time elapsed since
power-up or reset, and the input voltage from your boats
electrical system.
The time, speed and distance calculations are useful for
tracking your progress on a trip. The input voltage is useful
for determining the condition of the charging system of the
boat. When used in a portable application or whenever the
200DX is operated from a battery source, the voltage
number can he used to determine battery life. The 200DX
will operate at voltages from 10 to 20 VDC. Voltages in
excess of 20 or less than in 10 VDC cause the unit to power
off.
