6. HEADPHONE: Connect a headset (not included) to this stereo output for private listening.
The headphone volume is controlled by the Model Three’s volume knob. Connecting a pair of
headphones will mute the Model Three’s speaker. This jack accepts a 1/8" stereo male mini
plug. Avoid using headphones at high volume levels to prevent hearing damage.
7. SUB OUT: Connect Tivoli Audio’s Model Subwoofer (sold separately) to this output to enhance
the bass. This jack accepts a 1/8" stereo male mini plug.
8. AUX IN: To hear audio from another device, such as Tivoli Audio's Model CD, connect the
device’s audio output to this stereo input and switch the source knob to Aux. Note that you
may need to adjust the volume level differently for an auxiliary device than the level normally
used for radio listening. This jack acceptsa 1/8" stereo male mini plug.
9. REC OUT: You may record from the Model Three by connecting a cassette deck or other
recording device to this fixed level, stereo output. You may also use the Model Three as a
high-performance AM/FM analog tuner by connecting a preamplifier or integrated amplifier
to this output. The Model Three’s speaker will not be muted when using this output. This jack
accepts a 1/8" stereo male mini plug.
10. MIX IN: Connect your computer’s (or other device) audio output to this stereo input to hear
audio mixed-in with either the tuner or auxiliary device if one is connected. The volume level
of this input must be adjusted at the source. This jack accepts a 1/8" stereo male mini plug.
11. MONO/STEREO: This switch should remain in the Mono position unless the rightDual Alarm
or Stereo Speaker (sold separately) is connected, in which case the Stereo position should be
selected. If you are using the Dual Alarm or Stereo Speaker and have the switch set to Stereo,
you may wish to experiment with this switch during radio listening, as the Mono position may
help to clean up FM static noise. The Headphone and Record outputs are Stereo and are not
affected by this switch, unless the Source knob is set to AM (which is always Mono) or FM and
this switch is set to Mono.
12. TIME SET: Briefly press and release this button to advance the hands in small increments.
Press and hold this button to continuously advance the clock’s hands. Release the button
when the clock is set properly. Be sure the alarm button is in the Off position when setting the
time. See “How to set the clock”.
13. ALARM GRILLE: The alarm beep emits from this grille. Do not block this grille.
14. BATTERY BACK UP: Remove the battery cover and install a fresh major brand 1.5V “AA”
alkaline battery, observing correct +/– polarity. The clock operates off of the battery continuously
and the battery also acts as a back up. In the event of a power failure, the battery back up
will maintain the clock’s operation and sound the wake-up tone if the alarm button is in the
On position, provided a fresh battery is correctly installed. The clock face will not illuminate
and the radio will not operate during a power failure in order to conserve battery life. Check
the battery’s strength annually and replace only with a major brand, 1.5V “AA” alkaline battery.
If the clock stops operating, replace the battery. To reduce the risk of fire or injury, do not
leave a dead battery in the clock. Do not dispose of the spent battery into a fire. Do not open
or tamper with the battery. Do not recharge the supplied battery. Dispose of the spent battery
according to your state/country's regulations. Remove the battery if the Model Three is to be
stored or unused for a long period of time. See also “How to set the clock”.
