KBE MultiWatch2.0 Instruction Manual - Displaying The Time:
Displaying the Time:
To enable the display, simply give the face
of the watch a firm tap with your hand, table,
wall, or any other firm object (just don't hurt
yourself or others).
The display will turn on for about five seconds
before turning off again. If the button is pressed
again while the display is still active, it will
switch the current number base. The bases rotate
in order: Binary, Octal, Decimal, Hexadecimal,
and back around. Once the display turns off, the
watch will remain in the same number base until
it is changed via the method above.
But, What Does it All Mean:
Below you will find a quick tutorial on
understanding the four different number bases, if
you are still having some trouble it is
recommended to do some searching on the
Internet.
Decimal:
This is the standard numbering system we
use in everyday life, 0-9. The numbers on the
display will look like the following:
Octal:
This number base is very close to
Decimal, however, instead of counting from 0-9
and then adding one to the tens place, it counts
from 0-7 and then adds one to the tens place. As
an example, below is a quick arithmetic way to
convert 17 decimal into octal:
17 – 8 = 9 ones remain + 1 tens
9 – 8 = 1 ones remain + 2 tens
17 decimal is equal to 21 octal.
There may be easier ways to convert this, each
person is different.
Hexadecimal:
This number base uses the number 0-9 and
A-F to count ultimately from 0 to 15 (using one
digit as opposed to two) then adding 1 to the tens
place. The digit displays above, in addition to the
ones below, are used to convey the time:
As an example, below is a quick arithmetic way
to convert 45 Decimal to Hexadecimal:
45 – 16 = 29 ones remain + 1 tens
29 – 16 = 13 ones remain + 2 tens
13 Decimal in Hexadecimal is D + 2 tens.
45 Decimal is equal to 2D Hexadecimal.
Binary:
This is most likely the hardest base to get
the hang of. Each digit of the display has 4
vertical segments (and three horizontal that are
not used in binary), the top row of them spanning
all four digits is the hours while the bottom row
spanning all four digits is the minutes. The best
way to describe binary is that it increments from
right to left starting at one and doubling every
time. The far right place is worth 1, one left of
that is worth 2, one left of that is worth 4, and so
on. If a segment is lit, that places worth is added
to the total for that line. Let's do a few examples:
The time is 18:49
The time is 7:14
The time is 00:00 (midnight)
