How to discard this product

Discard this product according to local regulations for the disposal of industrial waste. For disposal in 
the USA, see the homepage of the Electronics Industries Alliance (http://www.eiae.org/) for the
correct method of disposal.

How to discard a used battery

Some FURUNO products have a battery(ies). To see if your product has a battery, see the chapter 
on Maintenance. Follow the instructions below if a battery is used. Tape the + and - terminals of bat-
tery before disposal to prevent fire, heat generation caused by short circuit.

In the European Union
The crossed-out trash can symbol indicates that all types of batteries 
must not be discarded in standard trash, or at a trash site. Take the 
used batteries to a battery collection site according to your national 
legislation and the Batteries Directive 2006/66/EU.

In the USA
The Mobius loop symbol (three chasing arrows) indicates that
Ni-Cd and lead-acid rechargeable batteries must be recycled.
Take the used batteries to a battery collection site according to
local laws.

In the other countries
There are no international standards for the battery recycle symbol. The number of symbols can in-
crease when the other countries make their own recycle symbols in the future.
