• HOW TO CHANGE THE CERAMIC FILTER
This model is used two ceramic filters of CF2 and CF3.
You must use same type of color marked ceramic filters in
order to meet same specifications.
Therefore, the ceramic filter must change two pieces together
since it's supply two pieces in package as a spare parts.

Setting the Clock
1. Plug in the unit.
The display will flash “AM 12:00”.
2. To set the hour, while holding down CLOCK, press TIME
SET H. When the correct hour appears in the display, release
CLOCK.
3. To set the minute, while holding down CLOCK, press TIME
SET M. When the correct minute appears in the display,
release CLOCK. The clock will begin to operate when you
release TIME SET M.
• Each press on TIME SET H or TIME SET M advances the
displayed number by one.
• The minute digits advance to “00” after “59”. The hour digits
do not advance by pressing TIME SET M.
• To adjust the time exactly to the second, release TIME SET M
simultaneously with the time signal.
Playing the Radio
1. Set the Function selector to RADIO ON to turn on the radioand adjust VOL. (volume)
2. Select BAND and tune in a station using TUNING.
• To turn off the radio, set the Function selector to OFF.
• To improve radio reception
FM: Extend the FM wire antenna fully to improve reception.
AM: Reorient the unit for optimum reception.
A ferrite bar antenna is built into the unit.
Setting the Sleep Timer
Enjoy falling asleep to the radio using the built-in sleep timer that
shuts off the radio automatically at a preset time.
1. While listening to the radio, set the Function selector to OFF.
2. Press SLEEP.
The radio turns on. It will go off after 59 minutes.
• To turn off the radio before the preset time, press SNOOZE/
SLEEP OFF.
• Every time you press SLEEP, the sleep timer is reset to 59
minutes.
• When you set the Function selector to ALARM MODERADIO or ALARM MODE BUZZER, if the preset alarm time
comes while the sleep timer is operating, the radio or buzzer
sounds depending on which you set.
Do not operate the unit over a steel desk or metal surface, as
this may lead to interference of reception.
Setting the Alarm
To set the radio alarm, first tune in a station and adjust the
volume.
1. To set the hour for alarm, while holding down ALARM,
press TIME SET H. When the desired hour appears in the
display, release ALARM.
2. To set the minute for alarm, while holding down ALARM,
press TIME SET M. When the desired minute appears in the
display, release ALARM.
3. Set the Function selector to ALARM MODE RADIO or
ALARM MODE BUZZER.
The alarm will come on at the presettime and automatically
turn itself off after 119 minutes.
• To shut off the alarm, set the Function selector to OFF.
To sound the alarm at the preset time the next day, set the
Function selector to ALARM MODE RADIO or ALARMMODE BUZZER again.
• To cancel either alarm, set the Function selector to OFF.
• To doze a few more minutes, press SNOOZE/SLEEP OFF.
The alarm will shut off, but will come on again after about 9
minutes. You can repeat this process as many times as you like.
• To adjust the radio alarm volume, turn VOL. The buzzer
volume is fixed.
• To check the preset time, press ALARM.
