Improving the Reception

FM

The headphones cord serves as the antenna, so extend it as long as possible.

AM

An AM antenna is built into the unit. Rotate the unit horizontally until you get the best reception.

To improve stereo program reception

Set FM SENS to LOCAL if interference is prevalent when radio wave intensity is dramatically stronger. Under normal conditions, set to DX.

To obtain Powerful Bass Sound

Switch MEGABASS to ON.
To reduce bass tone, turn MEGABASS to OFF.
If the sound is distorted, turn MEGABASS to OFF.

Presetting your Favorite Stations - Preset Tuning

You can preset up to 15 FM stations and 5 AM stations. To access the stations, simply select the corresponding preset numbers (AM 1-5, FM 1-15).
All the preset numbers are preset to certain stations at the factory. To preset your favourite stations, delete the preset numbers you do not need or change the stations you wish to preset.
