ERR EE2
External EEPROM read/write test failed
EEPROM may be defective (front panel).
However, this message may also appear if
power is turned off/on too rapidly, or if the
power supply voltage “bounces” during
turn-on due to inadequate regulation. If the
power supply is not at fault, try re-loading
MCU firmware first; then try initializing
parameters (pg. 72).
ERR FP3
Missing display text in flash memory
Try re-loading FPF (flash memory).
ERR FW2
General firmware problem
Try re-loading MCU firmware first; then
try initializing parameters (pg. 72).
ERR IF1
RF board IF shift registers not responding
Try turning power off/on. If the problem
persists, contact Elecraft.
ERR IF2
Sub RX IF shift registers not responding
Try turning power off/on. If the problem
persists, contact Elecraft.
ERR IO1
MISO line stuck low (asserted)
*De-install option modules one at a time.
If no failing option module can be found,
there may be a problem on the RF board.
ERR IO3
KIO3B not responding
The KIO3B may be defective. Note: The
K3S can be operated temporarily without
the KIO3B installed. You’ll need to use
headphones, and there will be no computer
or AF I/O available on the rear panel.
ERR KEY
ERR PTT
Attempt to key the transmitter or activate PTT
during power-on
Usually caused by an external device
shorting KEY or PTT to ground;
disconnect such devices until they’re
initialized properly. Also see
CONFIG:PTT-KEY. If necessary, try
removing the KIO3B module or its digital
I/O daughter board.
ERR LPF
No response from LPF shift registers
*De-install option modules one at a time.
If no failing option module can be found,
there may be a problem on the RF board.
ERR PA1
KPAIO3A module not responding
*De-install the KPA3A module and set
CONFIG:KPA3 to PAIO ON. If this
eliminates the error message, the problem
is likely to be on the KPA3A module. If
not, the problem may be on the KPAIO3A
module; remove it as well, and set
CONFIG:KPA3 to NOT INST.
ERR REF
Missing KREF3 module
Verify that the oscillator can on the
KREF3 is fully plugged in. Make sure all
internal cables are plugged in between the
KREF3 and other modules. If this doesn’t
help, the problem may be on the KREF3
module or the RF board. Note: The K3S
cannot be used without a KREF3 module.
