To reduce the possibility of induced interference from the
engine’s generator and/or ignition system, choose a position as
far away from the engine as possible and run the cable from the
transducer as far as practicable from the engine. Do NOT cut
the transducer cable, but stow excess away from any possible
source of electrical interference.
USING THE INSTRUMENT
When power is connected to the instrument it will show the
depth and boat speed. Pressing TRIP will show the trip distance,
that is the distance since power was connected. Disconnecting
the power will reset the TRIP to zero. Pressing TOTAL will show
the accumulated total distance travelled. This total cannot be
reset. Pressing ILLUM will turn on the display backlight. The
lighting is concentrated over the active part of the display, the
top corners being omitted. Pressing ILLUM again will turn the
backlight off. Pressing SPEED will return to boat speed. The
instrument will show depth at all times. If the echo is temporarily
lost then the depth units will momentarily flash. If the echo is
completely lost then the display will show OUT.
SETTING THE MINIMUM DEPTH ALARM
This is done during normal operation. Press SPEED and TRIP
simultaneously. The instrument will show SHA, the bell and the
current minimum depth setting. Use TRIP to decrement the
setting and TOTAL to increment the setting. When the required
minimum depth setting has been selected press SPEED. This
will enter the new value into the memory and return to normal
operation. To arm the alarm press TRIP and TOTAL
simultaneously. Pressing TRIP and TOTAL simultaneously a
second time will disable the alarm (without altering the alarm
setting). The bell symbol will show only when the alarm is armed
and will flash when the alarm is active.
