Reassemble the KX3 case halves and apply external power. Do not install the batteries yet.
Turn the KX3 on (hold the B AN D -
and
AT U T U N E
switches simultaneously).
Hold M E N U
to enter the menu and turn the
OFS/VFO B
knob to select
BAT CHG
.
Turn the
VFO A
knob to select
CHG OFF.
Set the real-time clock to the current time (see pg 2). Set it within one minute of another clock so you can
confirm that the real-time clock does not stop while performing the next steps
.
Hold the
B A N D -
and
A T U T U N E
switches simultaneously turn the KX3 off and remove power from the
KX3 (always turn your KX3 off with the front panel switches before removing external power when no batteries
are installed). Wait about 1 minute and then reapply power and turn the KX3 on again. The KX3 runs a self-
diagnostic as it starts. The installation is good if no error messages are displayed.
Tap D I S P
and turn the
VFO B
knob to show the time on the VFO B display. Confirm that the clock did
not lose time during the time the KX3 was off with no power applied. This indicates that the “hold up” feature
the clock is working. Normally you can have the KX3 disconnected from external power and have the batteries
out for up to 5 minutes without the clock losing the correct time.
Final Steps
Disconnect power, open the case again and install eight NiIMH batteries with a capacity of 1900 mAH or
greater. Inspect each cell for damage to the plastic covering over the outside. Never use a cell with a damaged
covering. The plastic covering protects the cell from shorting against other objects such as the shield on the
KXBC3 module. The short circuit can produce extreme heat and may cause a cell to rupture, causing extensive
damage inside your KX3.
WARNING!
Install only NiMH batteries. Attempting to charge any other type of battery may result in
personal injury, fire and damage to the KX3.
Return your KX3 to normal operating configuration:
 Replace the KXPD3 paddles, if used.
 Reconnect any station cabling including antenna, microphone, etc., to your KX3.
That completes the Installation and Testing of your KXBC3 Module.
