Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

Forced Flash Mode
When taking photographs of subjects in strong light or with backlighting, dark shadows may appear on the image. Forced Flash Mode is used to soften shadows. The flash will operate in all lighting conditions.
q When the REC(ord)/PLAY switch is set to REC, press the FLASH button until the [ ] symbol appears on the LCD monitor. The Flash LED will blink.
The FLASH LED will light when the Release button is pressed lightly.
Note: The flash LED flashes while the flash is charging; a picture cannot be taken at this time.
w Press the RELEASE button.
The camera will take a picture with the flash.
Canceling the Mode Press the FLASH button repeatedly to select another mode. Flash Distance The recommended shooting range is approximately 0.6 m to 3.0 m if the flash is used. If the flash does not reach the subject, a dark, underexposed image may result. If the lens-to-subject distance is less than 25 cm (10 in.), the image may look washed-out.
