3. Pairing;
Bring the transmitter close to the receiver ( within 3 ft if possible ).
After a short time
the transmitter will lock to the receiver. When this happens the transmitter light will remain ON, a solid green.
The green receiver LED will go out.
No light on the receiver means it is locked to a transmitter. ( Or the power is off )
The mic should now be active.
The range extends to 150 ft. and through solid objects.
The “Vol +/- “ buttons on the right side of the transmitter will change the mic sensitivity and the resulting sys-
tem volume. One suggestion is to set all levels at the midpoint and adjust from there. Remember the Re-
ceiver also has a Volume adjustment.
For projectors there are also a “Mic Vol “ and the Output “Vol” controls. Also, the internal projector speaker
can be set in the ON or OFF state.
Please note that the headset microphone is a little more sensitive than the clip-on lavaliere type mic. The
transmitter can be worn by placing the lanyard ribbon around the user’s neck.
System operation
.
The system operation uses 48k digital audio sampling. There are 80 channels available for the transmitter and
receiver. The frequency of operation is 2.400 to 2.480 GHz.
Channel changing;
Changing the channel on the receiver will cause the transmitter and receiver to loose
their lock. The receiver channel can be set using the Ch + or - buttons.
Please turn the transmitter OFF for about 10 seconds. Then turn it back on and the transmitter green LED will
flash till it locks to the receiver. The receiver LED will also flash till the lock occurs and then it will go OFF.
A
flashing green LED indicates the system components are seeking a pairing.
.
Turning OFF the transmitter or receiver will require the system when turned ON to again seek and pair.
Low Battery
;
Operation with a low battery in the transmitter can result in weak signals which will result in noise and loss of
pairing.
A fully charged battery in the transmitter can operate for over 8 hours. The low battery is indicated by a red
LED. The transmitter battery is charged using the line plug adapter with the USB port. Use the USB to 3.5mm
mini jack cable. The battery is a rugged cell phone battery, Nokia BL-5B Lithium-ion, 3.7V . It is charged by the
5V DC from USB ports.
