WIRING

Connect the wires as shown in the diagrams on the opposite page. The LDT-3003 operates from 10 to 15 vdc (12-volt system). You can connect the wires as shown in the diagram at the top of the page using only one accessory switch (not included), which switches the unit's lights on at the same time the unit is turned on, or you can wire the lights to a separate switch as shown at the bottom of the page. Regardless of which wiring method you use, the LDT-3003 must be wired to a 2-amp fuse! Failure to fuse this product will void the warranty and could result in damage to the unit or your boat.

The unit won't be harmed if the power wires are connected backwards, however, it won't work until they're properly connected.

Make certain to connect the green wire to unswitched +12 volts. This keeps power on to the unit's memory so that the clock will keep running even when the unit is switched off.

Find a location for the speaker that is protected from the elements, but still lets you hear it.The typical mounting location is behind the dash. If the LDT-3003's wires won't reach the speaker, splice ordinary speaker wire to them.

SENSORS

The LDT-3003 can use the following sensors:

TS-W2BK

Two temperature sensors - Water and Temp 2.

TS-3BK

One temperature sensor - Temp 3 only.

We reccommend you use the LDT-3003 with the above sensors in the following combination:

One TS-W2BK. This gives you two temperature displays - Water and T2.

or

One TS-W2BK and one TS-3BK. This gives you three temperature dis- plays - Water, T2, and T3.

For example, you can connect the TS-W2BK temperature sensors and mount the sensor labeled "water" on the transom to measure surface water temperature and the sensor labeled "T2" in the live well or on the hull for outside air temp. The TS-W3BK has an extra connector so you can attach the TS-2BK temperature sensor to it, then attach the TS-3BK's connect to the LDT-3003 and have three separate temperature displays.
