EPLACEMENT
The memories for the ATU are backed up by a common Lithium backup battery (type CR2032 or equivalent). After two or
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.
In this case, please replace the ATU Backup Battery using the following procedure:
1. Turn the
FT-2000D
’s [
POWER
] switch “off,” then
turn the
FP-2000
’s [
POWER
] switch “off.”
2. Unplug the AC cable from the AC jack on the FP-
2000 rear panel, then disconnect both DC cables from
the FT-2000D rear panel.
3. Referring to Figure 1, remove the three screws from each
side of the transceiver and three screws from the top
edge of the rear panel. Slide the top case toward to the
rear about 1/2 inch (1 cm), then remove the top case.
4. Turn the transceiver up side down.
5. Remove the seven screws affixing the bottom case, and
then remove the bottom case (Figure 2).
6. Locate the Lithium battery on the left side of the Con-
trol Unit (Figure 3).
7. Turn the
BACKUP
switch “off.”
8. Follow the guidelines in Figure 4, and remove the old
battery, replacing it with a new one of the identical type.
9. Connect both DC cables to the FT-2000D rear panel,
then connect the AC cable to the AC jack on the FP-
2000 rear panel.
10. Turn the FP-2000 ’s [ POWER
] switch “on,” then turn
the FT-2000D ’s [ POWER
] switch “on.” Use extreme
caution, as high voltages are present inside the trans-
ceiver!
11. Turn the BACKUP switch “on.”
12. Turn the FT-2000D ’s [ POWER
] switch “off,” then
turn the FP-2000 ’s [ POWER
] switch “off.”
13. Unplug the AC cable from the AC jack on the FP-
2000
rear panel, then disconnect both DC cables from
the
FT-2000D
rear panel connectors.
14. Replace bottom case and its seven screws removed in
step 5, and then replace the top case and its nine screws
removed in step 3.
15. The ATU Backup Battery replacement is now com-
plete.

ˆ 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.
ˆ 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.
ˆ The exhaustion of the ATU backup battery of the
FT-2000D
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.
