WARNING! The bottom of the RSS should not be handled during sonar
operation, as this may cause physical discomfort and may result in
personal injury in the form of tissue damage. Handle the RSS only by
the antenna tower when it has been in the water.
WARNING! The RSS (Remote Sonar Sensor) is not intended for use by
children younger than 6 years old without adult supervision as the
RSS may represent a choking hazard to small children.
WARNING: This product contains lead, a chemical known to the State of
California to cause cancer and birth defects and other reproductive harm.
RSS Power
The Remote Sonar Sensor (RSS) has a separate, non-
replaceable lithium battery that has a shelf life of three years
and will last for approximately 400 hours of in-water use.
Discard the used RSS in compliance with local laws as you
would any electronic component or battery.
The RSS has contacts that perceive when the device is
immersed in the water. These contacts turn on the Sonar
Transmitter/Receiver and begin transmitting the sonar infor-
mation via RF (radio transmission) to the display. The RSS
automatically stops using power a few seconds after being
pulled out of the water.
