Buzzer Operation
The buzzer chirps once when power is first applied to the keypad and
for each key press during regular use. When an authorized access
code is entered, the system chirps twice to indicate readiness for a
secure operation (6th button press).
The system chirps twice for each button press while in Learn Mode.
When a new access code is defined, the system chirps 3 times.
Keypad Backlight Operation
When the e-PAD is in the normal state, the backlighting is at a low
level. When a button is pressed, the keypad backlight flashes bright.
The keypad backlight also has a power saving mode if voltage is
below 11 volts, the continuous backlighting is shutoff until the battery
is fully charged. When continuous backlighting is off, the keypad still
“wakes up” when a button is pressed. In this case, the backlighting is
activated for only one minute.
If the battery voltage is increased to 12.5V for 5 minutes, then the
keypad back lighting will return to low brightness level.
Teaching Keypad New Authority / Access
Codes
Change Authority Code
The following procedure resets the default authority and access codes.
It then assigns a new authority code. The authority code is only used to
teach access codes.
Notes:
• The memory for authority and access codes is NON-VOLATILE
and will not be erased if power is removed.
• Changing the authority code is the only activity that requires
access to the learn mode wire in the wiring harness.
