Frequency Storage. The MX385 NAV COMM allows up to 50 NAV and 50 COMM
preset frequencies to be stored in the memory for recall. The use of memory presets is
described in the following sections.
Clearing all frequency presets. To erase all frequency presets with one operation,
simply turn on the power to the radio while holding the TEST button depressed.
Examining/Changing/Inserting/Deleting frequency presets. These operations on
individual frequency presets are accomplished in EDIT mode. To enter EDIT mode, turn
on the power to the radio while holding the VT button depressed. When the radio is in
EDIT mode, the ACTIVE displays show the reference number of the preset and the
standby displays show the actual preset frequency. After the ‘clearing all frequency
presets’ operation as described above, the only presets of 121.5 and the default NAV
preset of 112.0 are displayed.
EDIT mode operations are performed on either the COMM or NAV preset list, according
to where the tuning ‘tic’ indicator is displayed. The tuning ‘tic’ appears immediately to
the left of the COMM or NAV standby displays. Pressing the N/C button toggles
between NAV and COMM preset editing.
Examining presets (EDIT MODE)
. Pressing the COMM F-F button will step to the next
frequency in the preset list. Pressing the TEST button will step to the previous frequency
in the preset list. Pressing COMM F-F when the last preset is displayed will cause the
first preset to display. Similarly, pressing TEST when the first preset is displayed will
cause the last preset to display. Warning: When there is only one preset in the list, the
radio will not appear to “do anything” when the COMM F-F or TEST is pressed. This is
because the current, previous, and next presets are all the same preset.
Changing a preset (EDIT MODE)
. Press COMM F-F or TEST until the preset to be
changed is displayed. Dial in the new preset frequency using the tuning controls and
press either COMM F-F or TEST.
Inserting (Adding) a preset (EDIT MODE). Press COMM F-F or TEST until the desired
insert point is displayed (the new preset will be inserted AFTER this insert point). Dial
in the desired frequency using the tuning controls and press NAV F-F. Remember that a
preset list may contain a maximum of 50 entries. Inserting presets that would exceed this
limit are ignored.
Deleting a preset (EDIT MODE). Press COMM F-F or TEST until the preset to be
deleted is displayed. Then press the VC-ID switch to delete. If the deleted preset was
not at the end of the list, all the presets that followed it are renumbered. Each preset list
(NAV and COMM) must always contain at least one entry. If there is only one entry
remaining in a preset list, it may not be deleted (It can, however, be changed to another
frequency).
