You will need to use the Forward and Reverse buttons on the CD player. Set the station by holding the button you want to set it to until it blinks and shows the station number.
To set more that 10 stations. Press the (>10) button and then enter 11 or 12 or so on and set the stations the same as above.

MIght be an antena problem. Cheapest a quickest way to find out if the problem, your local autoparts store will sell a cheap replacement antena. Pull out stereo use this antena to check if more stations are picked up or use speaker wire about a foot or so in lenght and stick the wire in the antena port of the radio and see if you pick up stations, if so then your antena needs replacing.

SOURCE: brand new lasonic i931 boombox wont turn on!!!

okay, i had a similar problem, and the problem turned out to be a bad connection. If you open up the battery box, in the bottom top left corner there is a positive connection wire that looks kind of like a "U".
this connection doesn't come in contact with the batteries, so you need to extend it by wrapping a small piece of wire or something to make it stick out more.

what we actually did was put a piece of 1/4 in. by 1 in. piece of copper flashing in the plastic slot and across the U shaped connector to increase conductivity and it works fine.

i hope this was helpful!

if you have preset buttons dial up your station and hold down the selected button until the number stops flashing
