SM41 Rev. 4.00 NPX138 Panel Mount Radio Manual
Section 3.0 Operation
3.1 Introduction
In addition to the general functions that are available on other FM radios, the NPX has
several features that extend its capability and make it easier to use. These features
include alphanumeric channel labeling, built-in operator help, scanning, optional guard
receiver, and numerous others.
For ease of use and operability, NAT uses the same control layout and operating
system in the NPX138 series of radios as it does in its popular Tac/Com family of radio
control heads.
In addition to this manual, there is a help function built into the radio comprehensive
enough to address most operational questions.
Many of the front panel controls have more than one function, dependent on the
operating mode of the radio. For this reason, they have multiple labels. When the radio
is in ‘Normal’ mode (
EDIT switch in the center ‘Off’ position), use the top label and when
the radio is in ‘Edit’ mode (either ‘CH’ or ‘ST’), use the bottom label.
3.2 Initial Operation
3.2.1 Power-up Help
Turn the NPX on by rotating the main volume control clockwise, away from the ‘Off’
detent position. The software revision number will briefly display, followed by a screen
presenting an option for use of the on-line Help system, as shown below.
If you push the HELP button, the radio will present a tutorial on the operation of the
radio. To advance through the tutorial, press HELP after reading each screen. To exit
this initial HELP function at any time, move the NEXT switch momentarily left or right.
