Installation Guide
Location Selection
Choose an installation position at least 300mm from compass and 500mm from radio.
Mounting Procedures
Requires a flat surface and a 32mm hole. Ensure gasket is correctly attached for water sealing.
Wiring and Connections
Wiring Connection
Keep cables away from noise sources. Connect red to +12V via fuse, black to ground.
Multiple Instruments
The M100 can be used individually or networked with other 100 series instruments.
Device Operation
Changing Display Functions
Configure upper and lower display sections for various readings like speed, depth, and temperature.
Depth Alarms
Configures shallow and deep water alarms with audible and visual alerts for depth deviations.
Set Shallow Alarm
Enter shallow alarm mode and set the desired depth value using specific key presses.
Set Deep Alarm
Enter deep alarm mode and set the desired depth value using specific key presses.
Select Temperature Units
Change temperature measurement units (°C/°F) by pressing and holding a designated key.
Select Depth Units
Change depth measurement units (metres, feet, fathoms) via key presses.
Timer Functions
Access and manage elapsed and countdown timer functions displayed on the lower screen.
Elapsed Timer
Records time from power up in hours and minutes, up to 99 hours and 59 minutes.
Count Down Timer
Counts down in seconds from a set value (1-10 mins) with audio beeps at intervals.
Select Speed/Log Units
Choose speed and distance units (Knots, kph, Mph) via key presses and display confirmations.
Backlighting On/Off
Toggle the display backlight on or off by simultaneously pressing two keys.
Simulation Mode
Enter or exit simulation mode by holding a key and switching power; affects settings.
Secondary Functions and Calibration
Secondary Mode Access
Access keel offset, transducer setting, and calibration options by holding specific keys.
Keel Offset Adjustment
Adjust depth display for depth below keel or waterline by setting a positive or negative offset.
Transducer Setting
Select transducer settings (1-3) to optimize for turbulence, clutter, or shallow water performance.
Calibrate Temperature Display
Adjust the displayed temperature reading using up/down keys and confirm by pressing a key.
Speed Calibration
Adjust displayed speed to match another source (e.g., GPS) using the speed comparison method.
Log Calibration
Calibrate the distance log by comparing traveled distance to the indicated log reading.
Troubleshooting
No Display Issues
Check DC power connections and polarity; voltage must be between 10.7 and 16.6 volts.
Speed Reading Problems
Addresses issues like no speed reading, low/high readings, or erratic readings due to fouling or cable breaks.
Depth Reading Problems
Troubleshoots no depth reading or erratic readings caused by transducer issues or cavitation.
Erratic Readings (Engine Running)
Mitigate interference from engine by rerouting cables or adding filters.
Simulation Mode Identification
Identifies simulation mode if speed is fixed around 10kts regardless of boat speed.
