Rotary Encoder
Your scanner is equipped with a multi- function control
knob mounted on the top-right of the remote head.
You can turn the knob right and left, and press it
to click. The rotary encoder functions are “context
sensitive”. You can select the desired rotary encoder
operating mode (volume or squelch) in the Global
Settings menu under Knob Dflt.
Set the desired rotary encoder timeout time in seconds
in the Global Settings menu under Knob T/Out.
Factory default function is volume control during
scanning. Pressing the knob once temporarily changes
to squelch control. After 5 seconds (settable) of
inactivity the knob reverts to its default function.
In squelch mode the default function is to scroll through
squelch levels while scanning. Pressing the knob once
temporarily changes to volume control. After 5 seconds
(settable) of inactivity the knob reverts to its default
function.
Use the squelch function to optimize reception. When
the squelch level is high, only stronger signals will pass
through the squelch gate, and weaker signals may not
be received. When the squelch level is low, the squelch
gate will be open even when no signal is present,
causing the scanner to scan slowly or to stop on
Objects even when no transmission is present, playing
noise only. The scanner works best when the squelch
gate is set so that it is closed when no transmissions are
present, but able to open when a desired transmission
occurs. The ideal setting for the squelch level is
between 9 and 11.
If you find that the scanner seems to be scanning
very slowly or stopping on frequencies with noise
only, increase the squelch level until normal scanning
resumes.
In menus, the rotary encoder scrolls up and down
through the menu items and a single press selects the
indicated menu option. When entering alphanumeric
data such as Scan List names the rotary encoder scrolls
up and down the character list (letters, numbers,
punctuation); a single press selects the indicated
character.
The rotary encoder can be used to adjust the backlight
level. Press POWER briefly with backlight illuminated,
then rotate the encoder to increase or decrease
brightness.
