The HI SWR LED will light up, and tuning settings, if achieved, will not be
memorized. Please investigate and resolve the high SWR condition before
attempting further operation using this antenna. The high SWR may indicate a
mechanical failure in the feed system, and such failures can lead to the generation
of spurious signals causing TVI, etc.

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 transceiver’s main [POWER] switch “off.”
2. Unplug the AC 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.
