1. Important Caution

2. Features

Always make all connections before plugging the unit into an AC power outlet. •

Do not leave the devices in a place neither with high temperature nor high humidity.•

Always do not handle the power cord with wet hands !•

Keep the devices away from re and heat sources. •

Operated in UHF band where there is less RF interference than the VHF band. •
Due to the PLL synthesized technology, the system can oer up to 961 selectable frequencies for •
choosing simultaneously.

e true diversity reception with 2 independent RF receivers ensure the stable transmission and •

reception.

Adjustable Pilot tone squelch control can eectively reduce the noise. •

Equipped with S.A.W. lter benets the interference-resistant. •

Tuned antennas can benet the stable RF reception.•

Built-in Noise Squelch circuity & Mute function are available to restrain the interference for •
signals.

Compact half-rack receiver design is considerable for the space saving.

•

Rugged metal housing can pass through the dicult environment. •
Equipped with balanced XLR and unbalanced output allow great convenience.•

Anti-interference design is available to work with every computer device.•

6. Recommendation

(1) In order to achieve the optimum reception condition and also extend the operating distance,

please leave a “open space” between the receiver and transmier.
(2) Keep the devices away from the metal objects or any interference sources, at least 50 cm.
(3) To avoid the feed-back eect, don’t leave the mic. to aim at the speakers directly.
(4) For best pick-up paern, please hold the middle of the mic. body.
(5) Remove baeries from the baery compartment when the transmier will not be used for a

long time.
(6)When you need to replace the baeries, please replace both baeries at the same time with

new ones.
