Tips & Common Rules for All Users:

1. The AC adapter supplied is designed for dry indoor use only. NEVER use the AC adapter outdoors or in wet conditions.

2. NEVER operate this transmitter without an antenna, or dummy-load connected.

3. For best results, find an open, unused frequency to transmit on (http://www.radio-locator.com). NEVER transmit on occupied

commercial radio station frequency; for legal and ethical reasons.

4. Always follow your local regulations regarding the proper use of an FM transmitter.

5. Only use power adapters supplied with your unit. Using other types of power adapters may produce background noise with your

transmitted audio and/or could damage your unit. NOTE 12 V 2 A is the recommended Power Adapter, never exceed 12 V!

6. When transmitting from a microphone; only use a stereo plug microphone, using any other type of microphone such as a mono plug

microphone will permanently damage your unit, see ―Instructions – 3. Option b)‖

7. Always ensure that proper antenna tuning methods are used. Be resourceful, this Instruction Manual is only a guide...

FM Radio Transmission is a very tedious task and many variables factor into how clear your signal gets.

Instructions:

1. Connect chosen antenna or cable from antenna to antenna port (B).

2. Connect power to the Power Jack (A). ―-OFF-― will be displayed.

3. Option a) Connect audio source using desired 3.5 mm/RCA x 3.5mm audio cable. Insert one end into Audio Input Jack (C) and other

end of the cable to audio output jack /headphone jack/RCA out of the source device (ie: MP3 player, iPod, PC, MAC, PDA, DVD player,

etc.)

3. Option b) Connect microphone by inserting a stereo plug-type microphone into the Microphone Input (D)

WARNING: NEVER USE A MONO MICROPHONE TYPE, DOING SO MAY CAUSE PERMANENT DAMAGE

4. You should pre-scan your local FM frequencies using an FM radio or

www.radio-locator.com

to find an unused frequency and plan to

set the transmitter and antenna to this frequency.

5. Optional—FOR ANTENNA UPGRADES ONLY. (Skip to Step 7 if not applicable.) Refer to the antenna's tuning section.

6. Power unit ON by pressing down Power Toggle (D). LCD will come on and display a frequency.

7. Adjust the transmitting frequency using the Frequency Toggle Buttons (E).

8. Set volume level on the source device. Optimal audio level will vary for each type of device and recorded audio volume. Generally

you should set audio level at about 40-60% and slowly increase to optimum level

TIP 1 If audio is set too high it will cause distortion in the receiving radio such as static rather than bass.

TIP 2 When using the 500 mW RangeStar FM transmitter with a PC or MAC computer the volume level will need to be optimized at all

three sources: (1) computer sound card, (2) Media player software and (3) FM receiver radio. Set audio level at about 40-60% and

slowly increase to optimum level, if audio is set too high it will cause distortion in the receiving radio. Audio should also be increased at

the FM radio receiver to optimum level. In addition, it is recommended to also toggle the music player's equalizer (iTunes, Windows

Media Player, etc.).

9. Set volume level on FM transmitter using Audio and Microphone Volume Controls (G & H) and then adjust on radio receiver: When

the source audio level is optimized you should be able to have full audio level range with the FM receiver radio without any distortion

and crystal clear audio. Repeat until sound is satisfactory.

NOTE The RangeStar FM Transmitter's volume should not be adjusted to match local radio station's volume levels. Please understand

that the RangeStar is an amateur version of their complex, professional equipment.

Setting and Adjustment of Output Power Special Functions

Applies to all 2010 V1.2 versions or later with two level power adjustment: High power (H):> 0.5W/500mW; Low-power (L):

<0.1W/100mW

1. First press and hold the power switch

(E) while inserting the power adapter into the Power Jack

(A).

(E) after LCD screen shows the "H" or "L". Through the Frequency Toggles ▲/▼ (F) "H/L". Press ▲or

2. Release the power switch

▼ to toggle the LCD screen display between H or L. Again, "H" is the output power > 500mW; "L" is. the output power <100mW.

3. Press the power switch

(E). The LCD screen displays the default setting of "108.00MHz". This is the highest frequency operator

prefers to use. Through the ▲/▼ it can be changed from 76.00 – 108.00 MHz. Again press the power switch

(E). Now the LCD

screen displays the default setting of "87.00MHz". This is the lowest frequency operator prefers to use. Again, through the ▲/▼it can

be changed from 76.00 – 108 MHz. Lowest frequency high-end cannot be higher than the highest frequency.

4. Press and hold the power switch

(E). Wait 3 seconds to exit the output power adjustment menu and LCD screen will display

"OFF". Again press the power switch "

(E) and the transmitter will power on and transmitter will begin transmitting.
