USING THE AUTOMATIC ANTENNA TUNER

LITHIUM BATTERY REPLACEMENT

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 front panel [POWER] switch “off,” then turn the rear panel’s [POWER] switch “off.”

2.Unplug theAC cable from the rear panel’s ~AC IN jack.

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 the AC cable to the rear panel’s ~AC IN jack.

10.Turn the rear panel’s [POWER] switch “on,” then turn the front panel [POWER] switch “on.” Use extreme caution, as high voltages are present inside the trans- ceiver!

11.Turn the BACKUP switch “on.”

12.Turn the front panel [POWER] switch “off,” then turn the rear panel’s [POWER] switch “off.”

13.Unplug theAC cable from the rear panel’s ~AC IN jack.

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.

CAUTION:

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.

QUICK POINT:

When theATU Backup Battery is replaced, all tuner memories will be erased, and new sets of tuning data will have to be stored.

NOTES:

￿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.

￿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-2000is 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.
