I’m Having a Problem, What Do I Do?
Do not attempt to repair the unit yourself. There are no user serviceable parts
inside, and opening it (other than the battery cap) will void the warranty. Please
visit our website at www.norcrossmarine.com for troubleshooting information.
1. Nothing Happens When I Turn the Power On:
Activate the “Depth Reading Mode” as per the instructions in this manual. Once
activated, place the sonar sensor near your ear and listen for a ticking sound.
The presence of the ticking indicates that the unit is producing sonar signals.
Make sure that you have installed a good set of batteries as per the instructions
in the “Installing the Batteries” section in this manual. You may also need to test
the batteries in another device to ensure they are fully charged. If in doubt,
replace the batteries with ones from a newly opened package.
Below freezing temperatures are extremely harsh on the electronic components
within the Handheld Sonar System PX. It is important that you keep the unit in
temperatures above -4º F (-20 ºC) during operation. This may require you to
keep the Handheld Sonar System PX in a jacket pocket or other warm place
between uses.
If you are going to be using the Handheld Sonar System PX in temperatures
below 20º F (-7º C) you must use Lithium ‘AA’ batteries. Cold temperatures sig-
nificantly reduces power output of Alkaline batteries, which will reduce the per-
formance of the Handheld Sonar System PX
2. The Depth Reading Is “---”:
Make sure that you are operating the unit in depths between 2.5 and 200 ft (1
to 61 m) . Be aware that the depth is measured in the direction that the unit is
pointed. Holding the unit perpendicular to the water surface will ensure accurate
readings. If you’re trying to “Shoot-Thru” cce or a boat hull, make sure that you
are following the instructions precisely. The most common cause for incomplete
readings using these methods is air between the sonar sensor and the water
surface. If in doubt, try operating the unit directly in the water as per the instruc-
tions in the “Obtaining Depth Readings” section of this manual (make sure the
depth is between 2.5 ft and 200 ft (.8 to 61 m)).
3. I See Fish Under the Unit, but Nothing Appears on the Display:
As with the depth reading, the Handheld Sonar System PX will not detect any
objects within 2.5 ft (.8 m) of the sensor. Keep this in mind as generally, fish
that can be seen from the surface are closer than 2.5 ft (.8 m).
4. The Depth Reading is Incorrect:
Make sure that you are pointing the unit perpendicular to the water when trying
to obtain depth readings.
Extremely heavy vegetation may confuse the sonar of the Handheld Sonar
System PX causing it to misinterpret the depth. If you are cert
ain that the read-
ings are incorrect under these conditions, discontinue use.
