VFO B Knob Friction Adjustment
Use the supplied 5/64" (2 mm) Allen wrench to
loosen the VFO B knob’s set screw.
Between the knob and front panel is a felt washer
which, when compressed, reduces the spin rate.
Move the knob in or out in small increments until
the desired rate is obtained, re-tightening the set
screw each time.
Real Time Clock Battery Replacement
K3S components or modules can be easily be
damaged by ESD (electrostatic discharge). To
avoid this, put on a grounded wrist strap (with 1
megohm series resistor) or touch a grounded
surface before touching anything inside the
enclosure. An anti-static work mat is strongly
recommended.
The battery for the real time clock/calendar is
located on the left side of the RF board. To access
it, turn power off, then remove the left side panel. If
a sub receiver module is installed (KRX3A), it may
be left in place.
Remove the old battery by gently prying it out of its
socket using a non-metallic tool.
Replace the battery with the same type of 3-V
lithium coin cell (CR2032, BR2032, equivalent).
The (+) terminal is clearly marked on the battery; it
must be oriented as indicated by the (+) symbol on
the battery contact. Re-install the KRX3A module
(if applicable) and the top cover.
To set the time, date, and date format, refer to the
following CONFIG menu entries: TIME, DATE,
and DATE MD. (Note: the CONFIG:BAT MIN
menu entry refers to a battery used as the DC power
source for the transceiver, not to the 3-V battery.)
