more years of heavy use, you may notice that the tuner memories are not being maintained, and that you have to re-tune
when returning to a frequency on which you had previously stored tuning data.

Use care in the handling and storage of the Lithium battery. It is small, and presents a choking hazard to small children;
therefore keep such batteries out of the reach of children at all times. Do not dispose of Lithium batteries in fire, and do
not attempt to re-charge them under any circumstances.
not attempt to re-charge them under any circumstances.
When opening/closing the case, take care with your screwdriver not to short out internal components, or touch them in
a way that will cause them to short out against other components.
The exhaustion of the ATU backup battery of the FT-2000 is a normal “wear and tear” situation, and the loss of the
backup voltage is not a “defect” or other condition covered by the Limited Warranty on this product. Accordingly, if you
do not feel capable of replacing the battery, and ask a service shop to do so on your behalf, a service fee may apply.
