With the set of keys available in NumPad mode, the user can send messages and control Pause and
Cancel. The fast callsign capture function is activated with the * key as well as send exchange with the Enter
key. NumPad mode should only be used with a Numeric Pad attached, since it affects some of the standard
keyboard mappings.

PTT Operation

The K45 provides a separate output that is enabled whenever CW transmission takes place. This output is
called PTT which is a misnomer since it has nothing to do with Push to Talk. In most cases the K45 PTT
output is used to key a linear amplifier or antenna switch. In those cases, it's desirable to assert PTT in
advance of keying (Lead In), hold throughout the keying interval, and then deassert it after keying is
complete (Tail). Some amount of Tail Time must be set for Lead-In to work. If Tail Time is set to zero, then
the lead in delay will activate between every letter. If Tail delay is set to bridge the gap between successive
letters, then Lead In will work properly. These delays are customized depending on an individual station
requirement to prevent arcing and protect receiver and transmitter inputs and outputs. The PTT output is
only available for Port 1 when PTT is enabled. A special PTT delay called Hang is similar to tail but only is
used for paddle sending. All of these delays are set in the configuration menus #1 and #2.
