This product uses a new generation of Japanese ROHM's chip FM stereo radio 
emission (BH1415F) Seiko-produced. This machine looks beautiful, with gold-plated 
aluminum chassis fully closed, compact structure, shielding is good, solid firm, due to 
BH1415F integrates PLL frequency PLL, audio pre-emphasis, limiter and low pass filter 
circuit, the transmission frequency stability, quality class, a high degree of stereo 
separation performance than the other forums using ROHM's predecessor (BA1404 ) 
produced a more superior transmitter. Very suitable for the various tertiary institutions, 
living quarters, towns and villages and the need to launch high-power high-fidelity audio 
signals to suit the occasion. 

The machine operation simple and easy wiring. Firing frequency of the front panel 


display using LCD screen, step to 100Khz, through the bottom of the "+" and "-" 
two touch switches to regulate the frequency of upward and downward, fast and intuitive. 
“Audio” as the standard 3.5mm stereo input jack, you can easily connect to most home 
stereo audio playback device. Back on the “DC12V" for 6.5mm power input socket, 
through the external 12V/5A (optional larger current margin of) power adapter input 
(jack inside the cathode), power adapter, switching power supply recommended , such 
as notebook computers and LCD monitors and other external switching power adapter, 
connector terminal with a magnetic ring filter is best, so can greatly reduce the power 
of the transmitter interference, conditional use 12V power supply to the battery of the 


transmitter .

As shown above, for connecting external sound source audio lines connected to 
"AUDIO" interface. Should use more cable shielding performance audio cable, 3.5mm 
plug. 

Connect the microphone 

Connected to the "MIC" jack. And audio cable, like a good selection of shielding 
wires, plugs for 3.5mm. (Note: The microphone for the microphone type is Electret 
condenser microphone. 

Boot 

After all the preparation work was ready, the power adapter open, the transmitter 
is in standby mode the screen displays "OFF": 

Click on the front panel , The transmitter will enter the normal working state, 


and then, through the + or Its two buttons to adjust the working frequency of 


the machine required frequency.

Special features of the setting and adjustment 


1.Power Adjustment 

The machine output power sub-two tranches: Power profile (H):> 5W; 
low-power profile (L): <1W 

First of all, turn off the power adapter (or disconnect DC12V), finished in the 
transmitter power lines disconnected state, press and Hold El And then connect the 
power adapter (that is, DC12V connected to the transmitter), 3 seconds after release 


the button, this time into the power to adjust the state, LCD display shows “L” or "H": 





Click "+", set to high power (H), according to , set for low-power (L), select 
the desired power profile, and then © | Power is set, it will go to set the frequency 
range of the state. 
2. Attention 
(1)Before booting, be sure to had connect the antenna. It is strictly prohibited 
empty boot. 
(2) Audio cable must use shielded cable. 
(3) The power adapter output DC voltage is selected as clean, so as not to interfere 
with the transmitter. 
(4) Avoid extreme hot or humid environment. 
3. General troubleshooting. 
A.The frequency can not be adjusted. 
Reason: to set the frequency range may be errors, high-frequency than low-end 
high frequency. 
Solution: re-setting the relevant parameters (see instructions ) 
B. To open the boot method, press the power button, the flash look, LCD displays 


"OFF" 


Reasons: low-voltage, over-power adapter with a lower load capacity. 


Contact: Rita Email: [email protected] Skype: rita.cai87 Web: www.fmuser.net 


Solution: replace the power adapter (12V/1A) 
C. Sound distortion serious 
Cause: The input audio amplitude is too large. 
Workaround: down the volume of the sound source. 
D. Launch proximity 
Reason: There may be power set to low power file (L) 


Solution: re-setting power parameters.
