AM RF Gain

The AM RF GAIN control affects signal strength for SW reception. If the signal is weak, turn AM RF GAIN toward MAX. If the sound is distorted, turn AM RF GAIN toward MIN.

BFO Switch and BFO Dial

Some SW and LW stations transmit in Morse Code using a form of transmis- sion called continuous wave (CW). Some SW stations use a special type of voice transmission called single sideband (SSB).

To tune to a CW or SSB station, select the band and frequency and adjust the antenna. In addition, set the BFO switch to ON. Then, beginning at its midpoint, slowly adjust the BFO dial until the reception becomes clear.

For the FM and MW bands and for SW stations that do not transmit in SSB or CW, set the BFO switch to OFF. The BFO dial has no effect when the BFO switch is set to OFF.

Tone

In all bands, adjust TONE for the best sound.

Silencing the Alarm

When the display shows the alarm time, the radio turns on or the buzzer

sounds and flashes on the dis- play.

After several seconds, the buzzer’s volume increases. After a few more seconds, the volume increases again.

The buzzer automatically stops or the receiver automatically turns off after 60 minutes. To silence the alarm sooner, press RADIO POWER. The flashing disappears and the alarm sounds

again the next day at the set time.

Turning the Alarm Off/On

To turn off the alarm so it does not sound again, press STANDBY. While STANDBY flashes, press C.
