·

The master selects the device between USB memory and SD memory card. To do this, both

devices should be connected or one device should correspond to the other (USB to SD or SD
to USB). Otherwise, this key operation is ignored.

·

Stop after selecting the device at the top tune of the device.

·

REPEAT and RANDOM settings return to the initial values.

·

When inserting both USB Memory and SD Memory card, or neither USB Memory nor SD

Memory card, the master precedes USB Memory.

REPEAT

·

This key changes the mode of repeat.

·

Press of

“REPEAT” KEY toggles like: “repeat all tunes in memory”



“repeat one tune”



“repeat within folder”.

·

When selecting

“repeat within folder”, the master repeats AAC/WMA/MP3 files within the

folder being played. The initial setting is

“repeat all tunes in memory”.

RANDOM

·

This key plays the range of



128 files from the current one being played in the order of sort at

random.

·

“RANDOM” KEY is enabled to change mode only during play, pause or stop.

VI.2.2 LED operation

Seven types of LEDs used to display the LSI operation states are controlled. Table VI.2.2 shows the types

and states of LEDs.

Table VI.2.2 Types of LEDs and operation description

Types of LEDs Operation description

LED_ERROR

Lights when an error occurs. This happens in the following cases:
(1) Neither USB memory nor SD memory card is connected. No AAC/WMA/MP3 file

exists even if these devices are connected.

(2) Communication error or disconnection occurs in the memory being played.

LED_PLAY

Lights during play. Blinks during pause.

LED_PSD

Lights when SD memory card is connected and played.
Blinks when SD memory card is connected but SD memory card is not selected.
Goes off when SD memory card is not connected.

LED_PUSB

Lights when USB memory is connected and played.
Blinks when USB memory is connected but USB memory card is not selected.
Goes off when USB memory is not connected.

LED_ACCESS

Lights during access to USB memory or SD memory card.

LED_RANDOM Lights during random play.

LED_REPEAT

Lights during folder repeat. Blinks during repeat of one tune. Goes off during repeat all
tunes in memory
