FREQUENCY LISTS
The TR-8 stores 25 frequency lists, each containing up to 99 frequencies. Frequencies within each list are
always sorted in numeric order by frequency. Each frequency can be assigned its own unique label to help
you identify the corresponding transmitter. Each list also has its own label.
From the Menu, you can choose which lists are active at any given time, and multiple lists can be active at
the same time. When a list is active, you can easily tune the receiver to any of the list’s frequencies using
one of the following methods instead of entering in the frequency on the keypad:
•Scroll through the list(s) using the Tune knob
•Manually scan the list(s) using the “Next” and “Prev” soft keys
•Automatically scan the list(s) using TR-8 auto scanning
•Jump directly to a frequency by entering its position in the current list
(e.g., enter “3” for the option to jump directly to the third frequency in the current list)
Depending on how you navigate the list(s), the TR-8 may (or may not) skip frequencies marked for skipping,
as described in the remainder of this section.
SKIP (MARK/UNMARK) FREQUENCY
To mark a frequency on a list for skipping, press the
“Skip” (zero) button. An “S” icon appears as shown here.
Press the button again to unmark and restore the
frequency to the scanning sequence.
Press and hold the “Skip” button to unmark all of the
frequencies on the active list(s). The “Skip” button also
works the same way in the List Maintenance menu, any
time the TR-8 is displaying the contents of a list.
During auto-scanning, the TR-8 skips frequencies marked for skipping. During manual scanning, the TR-8
optionally skips these frequencies.
SCROLLING THROUGH LISTS
Normally, the tune knob allows small adjustments to the current frequency, known as fine tuning.
However, if you click the tune knob, its function toggles between fine tuning and scrolling through the
active frequency list(s), as shown by an underline marking on the display. Note that scrolling is a temporary
function, and the tune knob automatically reverts to the fine-tune function a few seconds after you settle
on a frequency. Scrolling never skips frequencies, even those marked for skipping.
Scrolling is available anytime at least one list is active and the TR-8 is on the home screen. Scrolling works
even when auto-scanning.
MANUAL SCAN
When at least one frequency list is active, use the “Next” and “Prev” buttons to step through the
frequencies on the list(s). These buttons can optionally skip frequencies marked for skipping. Press and
hold either button to change the function of both buttons to skip, or not to skip, those marked frequencies.
The behavior of the Next/Prev buttons can also be changed in the User Preferences menu.
