Changing Display Brightness
There is one additional display function, which is the INTENSITY/CONTRAST setting.
On LED controls, this is selected by advancing the cursor past the bottom radio. The
display brightness screen below will be shown. On a two radio control, simply press the
RADIO button two times if the cursor is set to the top radio, or once if set to the bottom
radio, and the screen below will appear. The display brightness is adjusted with the
SELECT switch. Press RADIO again to return to normal operation.
CHAN - = Dimmer
CHAN + = Brighter
On LCD controls, there are two ways of making this adjustment, either by the screen
described above, or by a DISPLAY/CONTRAST pot, if there is adequate room on the
front panel. The Contrast control changes the contrast ratio and viewing angle of the
LCD to suit varying light and position situations. If the display is subjected to dramatic
temperature extremes (hot or cold), it will alter the chemical properties of the display,
and may require an adjustment of this control to return the appearance to the desired
presentation.

Scanning
Scanning is an automatic internal function that rapidly samples radio channels under
operator control. The operator may select one of several predefined modes that control
how the radio will carry out this function (via the STATUS EDIT function), and has a
front panel switch to send the radio into this mode of operation.
Scanning is very useful for checking radio traffic on one or more channels, while
working a 'home' or monitor channel (the one the radio was on before scanning was
selected). When scanning is active, all CTCSS/Subaudible Tone or DPL Functions are
ignored, and with the NT150, the radio does not test for these conditions when
determining that a channel has been found. Tones remain active for squelch control.
This is because the delay to test for tones is so long compared to the radio lock-up time,
that scanning would be seriously compromised. NT-series transceivers scan at rates of
