七．Working mode：

1 Electricity（3.0v--------4.5v）
2 Long press “POWER” to be on, the LED1 flashing once, then to put out . And LED2 kept flashing.

Flashing frequency is 5s once ;that means the module can work if connecting the bluetooth device.
But no 2s once.

3 The module will automaticly search the previous bluetooth device when power on. It will exit the

connection without searching the previous device in 10s. Otherwise, it will connect automaticly.

4 At boot state, long press “POWER” button, the LED1 will flash once then put out to power off .

At this moment , two lights don’t bright .

5 At boot state, no finding the previous connection, you must connect again. Long press “POWER”

button without let your hands go until the LED fast alternate flashing. Then it go into the match
mode. At the match mode, you can connect with your mobile phone, computer and other bluetooth
device . The bluetooth name is F-3088 and password is 8888(The name and password can change
according to your requirements) .

6 It can transmit music if the module have connected with the bluetooth device. You can control by

the button: Previous, Next, Volume +, Volume – , pause and play.

7 If connected with the phone, short press”POWER” button to hang on and hang off when someone

calls you .

8 Through the MIC port to connect your microphone, you can call for hand-free.

八．Circuit connection note：

F-3088 external amplifier, must meet difference of the input amplifier. If not , must take an op-amp
balance two difference level, or you will have the impact of sound.

九．Attension：

A．Use environment: the wireless signal is widely influenced by the surrounding environment.
Obstacles such as trees and metal can absorpt certain wireless signal. Therefore, in the appliction , the
transmission distance has a certain influnce.

B．The bluetooth modules are supporting the existing system, placed in the shell. However, the
metal shell can shield the wireless frequency signal.We suggest not equip it in a metal shell.

C．PCB board：The antenna of the bluetooth module is PCB antenna, but the metal will weaken the

function of the antenna , the module is strictly prohibited to go line and pave tile when clothing the
PCB. It is better to hollow out.
