(where are the ‘6.35 MM jacks’?)

(i have plenty of ‘3.5mm –> 6.35mm adapters’)

*to plug into ‘pre-amp input port’ (2)*

(first plug in a 6.35mm adapter to the port)

(then plug in the ‘wireless receiver’ to the ‘adapter’)

.

*the receiver is powered by 2 ‘re-chargeable lithium polymer batteries’*

(the batteries are included)

(USB micro-B charging port)

(takes ‘2 hours’ to charge’)

(when it is charging, there will be a ‘red light’ turned on underneath the port)

(once it is fully charged, the light turns ‘green’)

(battery life is approximately ‘6 hours’)

.

(turn pre-amp ‘volume levels’ down when plugging in the ‘receiver’)

(to avoid ‘feedback’)

(slowly turn up the volume after wirelessly connecting a ‘mic’ to the ‘pre-amp’)

.

*’short-press’ the ‘power button’ on ‘receiver’ to turn it on*

(the ‘blue battery light’ turns on underneath the ‘power button’)

(when battery power is low, the ‘blue light’ turns red)

*short-press’ the ‘power button’ again to turn off the ‘receiver’*

(the ‘blue battery light’ turns off)

.

*charge the ‘transmitter’*

*there is a ‘*USB 5V micro-B port’ on the bottom of the ‘transmitter’)

(there will be a ‘red light’ underneath the ‘charging port’ while the ‘transmitter’ is charging)

(the light turns off when the ‘transmitter’ is fully charged)

.

*there is a ‘3.5mm microphone port’ on the top of the ‘transmitter’*

(plug in your mics here)

.

*’short-press’ the ‘power button’*

*the ‘front screen’ turns on*

.

*top left corner* –>

*battery power monitor*

.

*top right corner* –>

*antenna signal strength*

.

*left/right buttons*

(use them to navigate between the 25 ‘frequency points’)

(but i count ’20’)

(‘U00’ – ‘U20’)

.

*the ‘frequency’ is displayed in the ‘center’* –>

534.4 Mhz

.

*when both the ‘transmitter’ + ‘receiver’ are powered on, a ‘blue light’ will turn on ‘receiver’ when they are properly connected*

.

*RF / AF*

“‘radio frequency’ / ‘audio frequency’*

.

*the ‘blue light’ will flash ‘green’ when there is an ‘audio signal’ from the microphones*

.

*for problems with ‘frequency operation’* –>

*turn off ‘receiver’*

*turn on ‘transmitter’*

.

*hold down 3 buttons at once* –>

‘left button’ / ‘right button’ / ‘power button’

.

*let go when the ‘LCD screen’ starts flashing*

.

*turn on ‘receiver’*

.

*when the ‘blue light’ on the ‘receiver’ stops flashing, turn off the ‘transmitter’*

.

*turn ‘transmitter’ back on*

.

*try to connect the devices again*
