stage environment or a simple multi-room speaker system. The operating range from Master to the phone or
media device is approximately 30-50 ft, the Subordinate(sub) speakers can then be up to 150ft from the Master
speaker. Each TECH-LIFE BOSS can be a Master or Sub. Additional speakers are available to purchase

1 x Speaker with carrying strap
1 x Power adapter (AC100V-240V/DC18V 2A)

Getting Started
When you unpack the speakers there should be some power in the battery, however we recommend you
charge them for at least 6 hours to ensure best battery life. When charging, the RED charging LED (LED3) will
be lit, this will be off when fully charged.
Power ‘On’ the TECH-LIFE BOSS speaker by pressing and holding button (SW2) for 2 seconds – the Blue
LED (LED4) will Flash and the unit will say ‘Hello’ and announce the battery charge level Full/Medium/Low.
Bluetooth Pairing
On the Master Speaker - press and hold the button (SW5) for 2 seconds, the Speaker will announce
‘Bluetooth Pairing’ – now check your Bluetooth source (Phone /Tablet or other device) has Bluetooth enabled –
you will see the Bluetooth name of "TECH-LIFE BOSS", when your device is connected the unit will announce

‘Connected’. Both the Blue (LED4) will be static and lit – Please start your music playing and you can now
enjoy your music and listen to it on all linked speakers.
Multiple Linking
Short-press(1sec) the “Master” button (SW1) on the first unit, the Blue (LED4) and White (LED2) will flash –
now power ‘On’ the second TECH-LIFE BOSS speaker and then short press the Sub button (SW3), only the
white LED (LED2) will flash which indicates this speaker is in Sub mode (If the LED2 becomes solid mean it is
successfully grouped). You can do the same with the third and fourth speaker (up to 100 speakers can be
linked together – one Master and all others will be Subs). The master pairing mode lasts for approximately 2
minutes, when the white LED (LED2) is solid on the Master, it is no longer in grouping mode. Now you can
connect your music source to the master – the master unit is the only Speaker with both, Blue (LED1) LED
flashing and White (LED2) LED solidly lit (the Sub Speakers will only have the White (LED2) LED lit).
