being used. When you choose to manually adjust the
sensitivity, the
Twinscope
turns off the
AUTO sensitivity
mode and it will remain off until the “
AUTO
” soft key is
again selected. Note: when
AUTO
mode is turned on the
word
AUTO
will be displayed in reverse video (white
letters on a black background). To exit the sensitivity menu
and save your adjustments simply press the soft key labeled
“
LAST
” to return to the main forward looking menu.
(Press "
MENU
" to then return to the
Control Center
).
Alarm Adjustment
In the forward looking display or view, alarms may be set
for targets which are shallower than, deeper than, or within
a specific zone of adjustable depth settings.
To adjust or clear the alarm settings, press the soft key
labeled “
ALARM
” to bring up the forward looking alarm
menu choices. Pressing the "
DEEP
" or "
SHAL.
" soft keys
brings up sub-menus to set, adjust or clear the Shallow,
Deep and Zone Alarms. As either the up or down keys are
pressed and held down, or the large knob is rotated, a
vertical bar on the left side of the screen (just below the
boat icon) will move to show the area covered by the depth
alarm. In addition, a horizontal line will appear across the
display. Whenever a solidly displayed target appears at the
same depth as that covered by the alarm bar, the audible
alarm sounds to warn you of underwater targets or changing
bottom conditions. (
Note
: the horizontal line will
disappear a few seconds after the alarm is adjusted, but the
vertical bar will remain.)
The Shallow Alarm is often used to alert the user to
shallowing bottom conditions and the presence of
underwater targets such as fish, and when activated, will
sound a rapid beeping. The Deep Alarm is often used in
conjunction with the Shallow Alarm to define a depth
range. If the depth becomes less or greater than the alarm
settings, the audio alarm will sound as a warning. If the
Deep alarm is activated, the
Twinscope
will make a slow
beeping noise. A Zone Alarm can be created by using both
the Shallow and Deep Alarms. If the Shallow and the Deep
alarm bars on the left side of the display are “overlapped”
(that is the Shallow Alarm bar overlaps the Deep Alarm
bar) a new Zone Alarm will result and be displayed. When
the Zone Alarm is activated, the
Twinscope
will sound a
medium speed beeping.
Press the "
CLEAR
" soft key to clear the
alarm or alarms
you previously set. Press "
CLEAR
"
in the main alarm
