USING THE LCR
ADDITIONAL INFORMATION
The surface temperature gauge is a valuable fishing and boating aid. It will measure
water temperature in one-tenth of degrees and display the reading on the LCR screen.
The probe and computer controlled electronics have been designed for an accurate
indication and an extremely fast response time.
The Trolling Speed Indicator will give very accurate low speed readings, in tenths below
10mph, unlike ordinary speedometers. An accurate trolling speed can make the
difference in catching fish. The TSI-LCR also gives accurate high speed readings to 75
mph. If you do not have a surface temperature gauge or a trolling speed indicator, see
your LCR dealer or call the Humminbird Customer Service Department's number listed
in the front of this manual. If you want both the TG-LCR and TSI-LCR an accessory
switch is available to allow you to use both and select which one is being displayed on
the screen.
Simulator
Your LCR has a built in simulator. This simulator will display a typical underwater scene
which can be used for demonstration or for learning how to use and understand your
unit.
To activate the simulator, the unit must first be turned off. Next, push in the on/off button
for one to two seconds, until you hear the chirping sound. Then release the button and
the simulated display will begin.
In the simulator mode all buttons can be used. It should be noted, however, that
increasing or decreasing the sensitivity setting will not affect the information being
displayed.
Some additional things you should know about the LCR.
• Some polarized glasses might affect your view of the LCR display. It could result in a
prism or rainbow effect. This condition can possibly be improved by a slight adjustment
in tilt.
• If you get confused while in the manual mode, for instance, if you don't know where
the bottom is, then press the auto on/off button to turn on the automatic mode. The LCR
will find the bottom by selecting the proper sensitivity level and depth scale. You can
then go back to the manual mode it desired
• In order for your LCR to operate well at high speeds, you must have a properly
mounted transducer. Please read the transducer mounting procedure carefully.
• The transducer for the LCR is a l6° just like most standard Humminbird flasher units.
Other transducers, such as 32°, cannot be used.
