test failed
Follow the steps shown for ERR DS1.
ERR EE2
External EEPROM read/write
test failed
EEPROM may be defective. This message may also
appear if power is turned off/on too rapidly, or if the
supply voltage “bounces” during turn-on. If the power
supply is not at fault, follow steps shown for ERR DS1.
ERR FW2
General firmware problem.
d=nnn identifies the type of
error (report to Elecraft).
Follow steps shown for ERR DS1.
ERR IOA
RF board I/O expander
unresponsive.
Turn power on. Reload MCU and DSP firmware. If error
codes persist, turn power off, remove all option modules
(KXAT2 and KXIO2), and turn power back on. Turn off
associated option module enables in the menu (pg. 36),
then turn power off and back on. If this corrects the
problem, re-install the option modules one at a time to see
which one may be causing the problem. If errors persist,
the Control Panel or RF Board may have to be replaced.
Write down error codes and data values (on VFO A)
before contacting customer support.
ERR IO2
KXIO2 module error (real-
time-clock). d=nnn is the
specific error code (report to
Elecraft).
Turn power off for 10 seconds, then back on. If this
doesn’t correct the problem, re-seat the KXIO2 module
and repeat. If the problem persists, replace the KXIO2.
ERR KEY,
ERR PTT
Attempt to key the transmitter
or activate PTT during power-
on sequence. (Note: If ERR
PTT occurs, VOX transmit is
disabled in all modes. Re-
enable using MENU:VOX.)
Usually caused by an incorrect setting of MENU:MIC
BTN for the current microphone, or an external device
shorting the KEY or PTT line to ground, or a shorted
KXPD2 (or KXPD3) keyer paddle. Turn power off, then
disconnect the KXPD2 or KXPD3 (if applicable) and
everything plugged into the left side panel, except for the
power supply. Turn power back on. If the problem has
disappeared, plug devices back in one at a time to see
which one caused the error.
ERR OSC
Synthesizer IC unresponsive
Follow steps for ERR IOA.
