Installation Location Mounting The NAVMAN D100 is designed for above or below deck installation. Select a position that is: The mounting surface must be flat. Use the template to set the centre of the fixing hole. • At least 300mm from a compass • Drill a 32mm (1.25”) diameter mounting hole through the bulkhead. • At least 500mm from any radio • Protected from physical damage • Remove the fixing nut. Peel the protective paper off the foam gasket and attach the gasket to the rear of the instrument.
Wiring Connection • Keep electrical and transducer cables away from alternator or other noise generating electrical cables. Avoid connecting the instrument to power circuits that share loads with ignition, alternators, inverters and radio transmitters. Electrical power supply connections should always be as short as possible. • Connect the red wire to the positive supply via a 1 amp fuse or a 1 amp circuit breaker. Connect the black wire to the electrical ground.
Operation Select Units Depth Alarm On / Off Use the or key to cycle through the units of measure of feet, metres and fathoms. Press the key to turn the alarm on or off. The bell symbol indicates the alarm is on. The bell will flash when the alarm is activated. FEET MTRS MTRS FATH MTRS Backlighting On / Off Simultaneously press the and keys to turn the backlight on. Repeat this procedure to turn the lighting off.
Setting Alarms The shallow water alarm sounds when the depth falls below the selected value. The deep water alarm sounds when the depth exceeds the selected value. When the alarm is activated the beeper will sound continuously and the bell alarm symbol will flash. Set Shallow Alarm MTRS Use the Press the and SHALLOW keys to set alarm value. key to exit. Set Deep Alarm MTRS Use the Press the 8 and DEEP keys to set alarm value. key to exit.
Secondary Functions Set Display Dampening Keel Offset Rough water conditions, schools of fish and thermal layers cause erratic depth readings. Display dampening controls the rate that the displayed depth can change and will help remove these variations. There are three levels of dampening with d1 having the least effect and d3 having the greatest effect. When operating in shallow water or at high speed it is best to use a low level of dampening.
Troubleshooting Chart No display: Check DC power connections and DC polarity with voltmeter. Voltage must be between 10.7 and 16.6 volts. No depth reading (--) at all depths: 1. Check transducer for growth or multiple coats of paint. 2. Check the transducer cable for cuts and sharp bends. 3. Substitute the transducer with a known good transducer hold it over the side of the boat into the water and see if instrument functions. This isolates cause of problem (transducer or instrument).
D100 User Manual Addendum Use the ^ and the V keys to set the required value. Secondary Functions (cont.) Transducer Setting The Transducer Setting function enables the user to optimise the operation of the D100 for the particular transducer installed. Transducer performance varies widely, larger diameter transducers produce strong signals resulting in improved deep water performance but can suffer from reduced shallow water performance, due to transducer ringing.
