when scanning.

6.  Press the TUNING knob to confirm your setting. The display will return to normal

 

radio display.

“Stereo”, the radio will switch to stereo mode automatically if the reception is good.

Preset (1–10) button until the radio beeps and shows

 “Saved”.

5.  Repeat step 3 and 4 for the remaining presets. 

6.  Stations stored in the preset memories can be over-written again by following the  

 

above procedures.

A 3.5mm stereo Aux-In socket is provided on the side behind the rubber cover, for 

connecting an external audio device such as MP3 player or CD player (Aux cable not 

included with this radio).

1.  Connect an audio source to the 

AUX-IN socket. 

2.  Press the 

SOURCE button to select AUX input. Display will show “AUX IN”.

3.  Play the external player.

4.  Adjust the 

VOLUME of both the radio and the player for comfortable listening.

5.  After use, close the rubber cover to prevent moist or dust from entering into the  

 

sockets and radio. 

Notes: Never use the Aux-In socket in rainy or moist conditions to prevent moist from 

entering the radio. Keep the rubber cover well closed under these conditions. 

The Auto-Power management function will be activated in AUX mode. If there is no 

signal* from the Aux-In socket for a period of over 15 minutes, the radio will automatically 

switch to standby mode. Pressing the 

On/Off button will wake up the unit.

* Also when the incoming signal from the external device is too low and cannot be 

detected for a period of over 15 minutes by the Auto-Power management, the radio will 

switch to standby mode.

To prevent this raise the output level of the external device enough to be detected.
