SJDGSMMOD51FM MODULATOR

CM Precision Technology LTD GSM Mod 51 Wireless MP3 adapter User guide Setup Instructions: The GSM Mod 51 Wireless MP3 adapter is your own personal FM broadcast station intended for use exclusively inside and automobile with a 12v cigarette lighter outlet. 1. Plug the GSM Mod 51 Wireless MP3 adapter to the headphone jack of your MP3 player. 2. Plug the GSM Mod 51 Wireless MP3 adapter to your automobile 12v cigarette lighter outlet. 3. Set the GSM Mod 51 Wireless MP3 adapter to desired FM channel by setting the slide switch to the desired frequency. Note that there are eight (8) Frequency selections available: 88.1MHz, 88.3 MHz, 88.5 MHz, 88.7 MHz, 88.9MHz, 89.1 MHz, 89.3 MHz and 89.5 MHz. For best results, set the frequency to a vacant spot on the FM band. 4. Tune your FM radio to the same frequency as selected on the GSM Mod 51. 5. Select an album on the MP3 player and set it to playback, Adjust MP3 player volume control to normal volume setting like when using a headset. 6. Adjust FM radio volume control to desired level. 7. If audio seems loud and distorted, decrease MP3 player volume control. If audio seems weak and noisy, increase MP3 player volume control. The volume control on your MP3 player behaves like the volume control on a disc jockey console in a real broadcast station. There is an optimum setting for best FM audio fidelity. Once you have found that optimum setting, do not adjust any further and leave it alone, Use the volume control on your FM radio for normal adjustments of volume level inside to automobile. 8. When traveling, you may observe that reception may become noisy or altogether displaced by a commercial FM broadcast station. This is because you may be approaching the location of an FM broadcast station operating on the same frequency as the GSM Mod 51 wireless MP3 player adapter, In such a case, change the frequency of the GSM Mod 51 wireless MP3 player (step-3 above). 9. The MP3 can be charged while insert the power plug of the GSM MOD 51 Wireless MP3 adapter to the power port of the MP3 player.
