Introduction User Manual TuneFM ™ for iPod ® nano Introduction | 01 Introduction Congratulations and thank you for purchasing the innovative TuneFM from Belkin. This product is designed to play your iPod nano through your car, home, or portable stereo. Please review this User Manual carefully so that you can be sure to get the most from your iPod nano, virtually anywhere you go. | 02 Car Setup Instructions Car Setup Instructions 1. Turn down your car stereo’s volume. 2. Connect the Belkin TuneFM to your iPod nano (at the bottom of the nano). 3. Connect the included Auto Power Cord to your cigarette-lighter outlet in your car and to the bottom of your TuneFM for optional powering and charging in the car. The TuneFM transmitter function automatically turns on when the iPod is connected. It automatically turns off when the iPod is removed. 1. Tune your stereo frequency to a channel with a weak broadcast signal. The ideal channel is one that is not broadcasting a radio program, or is doing so weakly. 2. Insert the TuneFM into your iPod nano. The iPod backlight will turn on and the current transmitter frequency will be displayed on the iPod screen. 3. Press the ▲ or ▼ button on the TuneFM to select the transmission frequency chosen in step 1. The frequency will be visible on the iPod nano’s screen. Pressing and holding either button will provide faster tuning. 4. After displaying the current frequency for five seconds, the iPod screen will return to the iPod Main Menu. This happens whenever you make changes to the TuneFM’s settings. All settings—including transmission frequency and stereo/mono control settings—are permanently stored in memory at this time. Note: iPod playback will pause momentarily when entering and exiting the TuneFM control menu. Playback will quickly resume. Using the TuneFM Transmitter Using the TuneFM Transmitter | 03 | 04 5. Adjust the iPod nano volume to about three-fourths of the maximum. Adjust the volume of your FM radio to the desired listening level. NOTE: We recommend that you remove the TuneFM from the iPod when not in use.

To store a preset, select the desired frequency using ▲ or ▼ buttons. Press and hold the desired preset button (1, 2, 3, or 4) for two seconds. An audible beep sounds in the transmitted audio when the new frequency is programmed*. The iPod nano display reflects the change when the memory button is released by showing which memory button was pressed followed by the frequency saved in that memory position. * Do NOT remove the TuneFM from the iPod nano until it returns to the Main Menu screen or new settings may not be saved. 2. To transmit over one of your preset frequencies, momentarily press “1”, “2”, ”3”, or “4”. This will instantly tune the FM transmitter to the frequency stored in that preset. Transmission-Volume Setting Although the default volume setting will be ideal for most conditions, you may be able to improve the performance of the TuneFM by adjusting the volume of the transmitted audio signal. The TuneFM allows you to select one of five volume levels. You may wish to decrease the volume if you experience distorted audio. You can access the transmission-volume menu by pressing the “1” and “2” buttons simultaneously. TuneFM displays the current volume setting on the iPod, which is represented by “VOL 1” (low), “VOL 2”, “VOL 3” (default), “VOL 4”, and “VOL 5” (high). You can then change the volume level by using the up and down arrows. To accept your volume selection, simply wait for the iPod screen to return to the iPod Main Menu. Note: The iPod nano has a lower audio-output level than other iPod models, so a volume setting of “VOL 4” or “VOL 5” works best for iPod nano. Storing and Using Presets | 05 Storing and Using Presets ���������������������������������������������������������������������������������� ������������������������������������������������������� ������������������������� | 06Stereo/Mono Selection Stereo/Mono Selection ���������������������������������������������������������������������������������� ������������������������������������������������������� ������������������������� ���������������������������������������������������������������������������������� ������������������������������������������������������� ������������������������� Transmitting music in stereo generally gives you the highest-quality listening experience. However, you may get better FM signal reception by changing the transmission to mono. The TuneFM transmits in stereo mode by default. We suggest that you switch from stereo to mono transmission only if your car stereo is NOT receiving a clear signal from the TuneFM, or if you are listening to mono recordings such as audio books. You can access the stereo/mono transmission menu by pressing the “1” and “3” buttons simultaneously for two seconds. The TuneFM then displays the current mode setting, which is represented by “MONO” or “ST”. You can change the mode by pressing the up or down arrows. Either arrow will change between the two modes. The new setting takes effect immediately. To accept your mode selection, press one of the memory preset buttons, or simply wait for the iPod screen to return to the iPod Main Menu. Issue – The audio is distorted. Solution 1 Decrease the volume of your iPod nano until you no longer hear distortion. Keeping the iPod nano volume level at or below three-fourths of the maximum should prevent audio distortion. Solution 2 Tune your car stereo and the TuneFM to a different frequency. Issue…
