When you press
SEL
the display will look something like this:
ALARM
INIT
TIME
PM
In this example the LNFC would display time in a 12 hour format and
would flash the colon when the clock is running (fast rate > 0).
To change a function value you must first determine what the new decimal
value will be for the option switch. This is done by adding the “weights”
for each of the functions that you want to have set to “1.” For example, if
you want to have the time displayed in a 12 hour format, have the colon
flash when the clock is running (fast rate > 0) and disable the local alarm
then you would add the following values:
1 + 4 + 32 = 37
(12 Hour Format + Time Tick + Alarm Disable)
For any functions that you want to set to “0” simply don’t add in their bit weights.
Now that you have the decimal (base 10) value you need to convert it to its
hexadecimal (base 16) equivalent. You should already be familiar with this from
other Digitrax products. Nonetheless we have included a handy decimal to
hexadecimal conversion chart here.
