USING TAP, HOLD, and TOUCH CONTROLS
The following text conventions are used when referring to controls:
[Physical Switch] <Touch Control> {Knob}
All physical and touch controls are described in the FRONT PANEL
OVERVIEW section, which follows.
Using Tap and Hold Switch Functions
Each of the K4's physical switches has both a tap function (white label)
and a hold function (yellow label). A tap is a brief press, while a hold is
any press longer than about 1/2 second. For example, [RATE] is
a tap function, while [KHZ] is a hold function of the same physical
switch.
Using Touch Controls
The K4's touch screen provides quick, convenient access to the rig's
most-used features. Many of the icons and labels are also touch
controls.
Examples:
• You can touch VFO digits to select a tuning rate as an alternative to
using the [RATE] and [KHZ] switches.
• To bring up the mode-select button group, tap the mode identifiers
near each VFO display, or tap the [MODE] physical switch above the
VFO A knob.
• To select a receive antenna, tap the antenna name icons for each
receiver or use [RX ANT] and [SUB ANT].
