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!

Tuner Operations
Changing tuning grid (not available for all versions)
In North and South America, the frequency step between adjacent channels in the MW band is 10 kHz (9 kHz in some areas). The preset frequency step in the factory is 9 kHz. IMPORTANT! Changing the tuning grid will erase all previously stored preset radio stations.

Disconnect the system from the AC power supply (pull out the AC power cord). While holding down PROG and á on the main unit, reconnect the system to the AC power supply. � The display will show �GRID 9� or �GRID 10�. Note: � GRID 9 and GRID 10 indicate that the tuning grid is in step of 9 kHz and 10 kHz respectively. � The FM tuning grid also will be changed from 50 kHz to 100 kHz or vice versa.
