7.3.2
Entering SE Mode
First press and hold
FWD
Low for more than 3 seconds. This action on
FWD
will play
SE1 and cause the LED to blink once (if at the last message location, the chip will play
SE2 and the LED will blink twice).
While holding
FWD
Low, press and hold the
REC
Low until the LED blinks once. The
device is now in SE editing mode.
The LED flashing once indicates that SE1 is accessible.
7.3.3
SE Editing
When in SE editing mode, one can perform record, play, or erase operation on each SE
by pressing the appropriate button. For example, to record SE, simply press and hold
REC
. Similarly for play and erase functions, press and hold
PLAY
or
ERASE
,
respectively.
A
FWD
operation moves the record and playback pointers to the next SE sequentially.
The LED will blink 1~4 times after such operations to indicate which SE is active. If
FWD
is pressed while accessing SE4, the LED will flash once to indicate that SE1 is again
active.
While the LED is blinking, the device will ignore any input commands. The User must
wait until the LED stops blinking before any record, play or erase command can be sent.
7.3.4
Exiting SE Mode
First press and hold
FWD
until the LED stops blinking. Then, simultaneously press and
hold the
REC
Low until the LED blinks twice and SE2 (if present) is played. The device
has now exited from SE editing mode.
7.3.5
Sound Effect Duration
The duration of sound effects is determined by the sampling frequency selected. All sound
effects with the same sampling frequency have the same duration.
