MELODY OPERATION
The BT8018 can repeat one of any 7 melodies consequently.
ON-HOUR AND CONFIRMATION CHIME
The IZ8018 has a 0.75 sec timer circuit to prevent the melody starting by chime sounds of the watch chip and by confirmation
chime of chronograph or by signal below 0.75 sec.
MELODY START
The signals to start the melody are AC or DC signals which are over 0.75 sec after the first signal is given to BDIN.
The signal under 0.75 sec will put the IZ8018 in standby mode.
MELODY STOP
The melody does not stop until it plays to the end of the melody even if alarm signal is stopped. Though the alarm signal is longer that the melody
signal the melody does not repeat. If the melody is needs to be stopped midway it can be done by pushing either S
1
or S
