SYNCHRONOUS DETECTOR

When receiving AM broadcasting, if there is interference from adjacent strong
signals, you can activate the SYNC function to improve the reception.

1.

Press the

[SYNC]

 button to select between

"

"

 or

"

"

 for optimum

reception.

2.

To deactivate the SYNC function, just press the

[SYNC]

 button repeatedly with

the symbols

"

"

 and

"

"

 dispearing.

Notes:
1.

The standard model of receiving AM station is the best normally. If there is
distortion, or interfering within the AM station, please try to adjacent station
signals by activating the Synchronous detection function, it can improve the
reception.

2.

If the

"SYNC"

 symbol keeps flashing, it indicates that the radio signal is too

weak or the frequency is deviant. It is recommended to exit the synchronization
detection function as it is not able to function properly.

HOW TO IMPROVE FM / SW RECEPTION

Use the external wire antenna plug into the

[FM & SW ANTENNA]

 jack, and then

hang the other end outside the window for better FM and SW reception.

Caution:

 Do not install any external antenna at the area with thunder & lighting!
