Using a First Generation RSS
First generation RSS units still sold with other SmartCast™ products come in two versions, Channel A and Channel B (RF40A and RF40B), and are both
compatible with the PiranhaMax30.
NOTE:
When using either an RF40A or RF40B RSS with the PiranhaMax30, you will not get water temperature or grayscale sonar information, and you will not be able to turn on the LED
or change the channel on the RSS. You will still be able to read digital depth and bottom contour information.
NOTE:
When using an RF40A or RF40B RSS, make sure to select the matching channel from the CHANNEL SELECT menu on the PinranhaMax30 Control Head.
Maintenance
Your PiranhaMax is designed to provide years of trouble-free operation with virtually no maintenance. Follow these simple procedures to ensure your
PiranhaMax continues to deliver top performance.
If the unit comes into contact with salt spray, wipe the affected surfaces with a cloth dampened in fresh water.
Do not use a chemical glass cleaner on the lens - this may cause cracking in the lens.
When cleaning the LCD protective lens, use a chamois and non-abrasive, mild cleaner. Do not wipe while dirt or grease is on the lens. Be careful to avoid
scratching the lens.
Never leave the unit in a closed car or trunk—the extremely high temperatures generated in hot weather can damage the electronics.
RSS Maintenance
After using the RSS in salt water, wipe the affected surfaces with a cloth dampened with fresh water. The RSS Wet Switch
TM
pins must be rinsed with
fresh water after exposure to salt water to prevent corrosion.
If your RSS remains out of the water for a long period of time, it may take some time to wet it when returned to the water. Small air bubbles can cling
to the surface of the RSS and interfere with proper operation. Wipe the face of the RSS with a wet cloth to remove them.
Never leave the RSS in a closed car or trunk - the extremely high temperatures generated in hot weather can damage the electronics.
Troubleshooting
Do not attempt to repair the PiranhaMax yourself. There are no user-serviceable parts inside, and special tools and techniques are required for assembly
to ensure the waterproof integrity of the housing. Repairs should be performed only by authorized Humminbird technicians.
Many requests for repair received by Humminbird involve units that do not actually need repair. These units are returned “no problem found.” If you have
a problem with your PiranhaMax, use the following troubleshooting guide before calling the Customer Resource Center or sending your unit in for repair.
NOTE:
Retrieving the RSS too rapidly, or the repetitive rocking motion of rough water, can result in loss or distortion of the bottom picture. This will cause intermittent screen display. For best
bottom detail, perform a smooth and slow reel-in with constant speed and the rod tip up (holding the rod tip low or using a heavy line may cause the RSS to submerge and momentarily
lose radio contact). The RSS has a maximum transmit range of 100 feet (30 meters). If the unit is cast or drifts more than 100 feet away from the receiver, the signal may be inconsistent
or lost. Raising the SmartCast™ slightly above ground level will also increase signal capture.
If sonar performance becomes weak (i.e., there are bottom gaps or "0" depth
readings) the bottom of the RSS needs to be cleaned with a drop or two of a 5 to
10 percent solution of liquid dishwashing detergent and water. Use approximate-
ly one tablespoon detergent to 8 ounces of water to remove oils from the face of
the RSS, then wipe with a damp cloth.
