Sometimes, more than one character will flash. This is because the only valid choices
involve multiple characters, such as the fractional kHz entry for a channel frequency.
This is also true for tone code entries. The SELECT switch will slew through the
available entries from an internal table.

3.7.3

EDIT Switch


This locking, center-off switch selects the operating mode of the radio. For NORMAL
radio operation set the EDIT switch to the center or ‘Off’ position. Edited data stores
automatically when changed so when editing is complete, the operator need only set
the EDIT switch back to ‘Off’.

3.7.4

HELP Switch


You can access general operation HELP from the initial power-up screen (see section
3.2.1). If you require basic help when the NPX radio is already on, cycle the radio off
and then back on again (using the volume control or the external breaker). The option
for comprehensive help will re-appear.

3.8

Status Editing

There is simply not enough room on the compact front panel of the NPX radio to fit a
switch for every radio function. The solution for this is the use of status lines to display
and control features that do not require immediate accessibility via the front panel.

As when editing channel data, the display shows only allowable options. This mode can
also display the status of the radio quickly, without editing any data. The Status editing
process is identical to the channel editing process only the select switch does not
change any information.

To edit status line data, pull and lock the EDIT switch to the right (ST).
