batteries should be replaced within
a
couple of weeks
to ensure
continued safety of your RAM entries.
To replace the batteries, turn the unit
over on
a
soft surface and remove the
battery conpartment cover
(see Figure
4.1).
A
small tool, such
as a
screwdriver, may be necessary in
unlatching the
tab. Be
careful not to
break
this tab. Replace the batteries
with three high quality
AA
size "heavy
duty" or alkaline batteries. A
capacitor will keep the memory alive
for about 30 seconds
while changing the
batteries, thus do not remove the old
ones until the new
ones are ready for
installation.
Alternatively,
it
is
permissible
to the power
cable plugged in and the power on while changing the batteries,
in
which case memory will be retained
as
long
as
power
is on.
Be sure to insert the new batteries in the directions indicated
by markings
in the
bottom
of the battery compartment.
Incorrect
insertion won't damage anything but the memory won't receive any
power from
the batteries
Most quality brand-name batteries now have
"sell by" dates
printed on their packages.
Carbon-zinc batteries will last
for
at
least
a
year after installation while alkaline batteries
should last
for at least
2
years provided they
are installed
before the date on the package.
Rechargeable batteries should
not be used; the K2000 will not recharge them and their life
after charging on
an external charger will be only
a
few months.
Battery life
is not significantly increased by leaving your
K2000 on all the time; batteries
may even suffer heat
degradation
if the K2000
is left on continuously.
USER CALLABLE DIAGNOSTICS
If difficulty
is experiences with
a
third-party switch pedal
or
control pedal, the built-in user callable diagnostic program may
help in diagnosing the problem.
This program will display
on
the LCD exactly what the K2000's internal computer sees when the
pedal
is
used.
This can help determine if there really
is a
physical problem with the pedal or merely
a
programming problem
in your program
or setup.
The diagnostic can be used to check
out the keyboard and
built-in controls
as well.
To enter the diagnostic program, simply press the
4, 5,
and
6
buttons simultaneously when in the Program Mode.
The K2000 will
respond by lighting each LED in sequence and then displaying the
following on the
LCD:
