* MIN SUPPLY VOLTAGE NOW 7.5 V (was 8.0): Increases operating time  
when using an 8-cell NiMH battery pack. Recommended max power output  
is 3 W when operating from less than 9 volts, although 5 watts is  
possible in most cases.

* KEY OUT (ACC2) FOLLOWS CW DELAY SETTING: Prevents excessive  
switching of external equipment being keyed by the KX3’s KEY OUT line.  
Set desired delay using DLY switch.

* IMPROVED HANDLING OF UNINTENTIONAL KEYING ON POWER-UP: Includes two  
new error messages: ERR VOX (voice or audio-data mode VOX was  
activated) and ERR ACP (PTT was activated via the ACC2 jack with the  
given setting of the ACC2 IO menu entry). In the ERR VOX case, VOX is  
turned off. In the ERR ACP case, ACC2 IO is set to OFF.

* UP/DN MIC FUNCTIONS DISABLED IN AF DATA MODES (DATA-A and AFSK-A):  
In this case the user will have a PC audio cable, not an MH3, plugged  
in at the mic jack. Eliminates the need to change the MIC BTN menu  
setting when switching from voice to audio data modes.
