rejected. 8-5 is also illegal. Or if you entered just 9-2, the unit would read 9 as an
attempt to change the door open time and then reject a single digit new time.

Another source of the error signal would be an illegal attempt to enter a Program Code
of less than five digits
(after prefix 0-0). Finally, while programming multiple codes,
you will get an error signal if a code you’re attempting to program is a subset of one
already in memory or a duplicate (see Section 6.4).

PROBLEM-- Door opens on a short code that wasn’t programmed
This can arise through an unnoticed programming error. Suppose you want to program 4-
5-1-2. But when the unit is in program mode, you forget to put in the two digit memory
slot prefix but just directly enter 4-5-1-2. The microprocessor will accept this sequence
and interpret it as code 1-2 in memory slot 45. You test the code by re-entering 4-5-1-2
and the door opens because the sequence includes the real code, 1-2. Later it will be

noticed that the door is opening on 1-2 as this is such a simple sequence that it will be
entered. When you have any evidence that unknown codes (particularly short ones) are
in the unit, it is best to erase all User codes and reprogram.

PROBLEM-- Unusual operation complained of after some operating history
"Unusual" operation can be caused by the microprocessor in the CPU Board being
disturbed by electrical noise. Symptoms can vary quite a bit. The unit may forget its
codes, the action of the keypad beeper may become drawn out or erratic, the timer may
function at widely varying ranges, etc. To cure the problem, remove power (the
batteries) from the battery compartment, press any keypad button, and then replace

batteries (unit will beep). This forces the microprocessor to reset itself and reload its
program. If the unit has functioned for a long period of time without incident, this may be
an adequate fix. The problem may never reoccur but the end user should be made aware
of this simple fix if it should reoccur. All microprocessors can sometimes "crash" and they
are restored by reset.
