Warranty description

1. Be sure to put the warranty label indicating purchase date on the bottom of equipment to ensure your interest in maintenance and service.

2. Product warranty, starting on the purchase date indicated on “warranty label”, will last for one year; if the equipment does not have “warranty label”, the warranty period is 15 months from the manufacturing date. If a microphone is broken but not sent back with the equipment, the warranty period is 15 months from the manufacturing date of the microphone.

3. Within the warranty period, if the equipment is broken under normal use as instructed in manual, please contact the original selling store for repair.

4. When the product is returned for repair, to facilitate proper determination of cause of malfunction and of whether repair fee is needed, please ship back the equipment and microphone together.

5. Within the warranty period, our company provides repair service at no cost except for the following conditions that parts and repair may be charged: a.Damages due to natural disaster or irresistible outside forces. b.Damages due to drop, water, moisture, corrosion, foreign objects, missing

components.

c.The warranty does not cover consumable parts. (such as microphone capsule,

ball grille etc.)

d.Those without “warranty label” on equipment or with “warranty label” being

damaged and failing to identify warranty period.

6. Please keep the warranty properly. No replacement will be made if the warranty is missing.

5-1 How to connect the receiver

1. Connect the audio output of receiver to mixer or amplier

1.1 / ：

The XLR output jack or 6.3mm unbalance output jack can be selected to

connect the AF output to a mixer or amplier.

1.2 ：

(1) The XLR output jack or 6.3mm unbalance output jack can be selected

individually to connect the AF output to a mixer or amplier for volume

control.

(2) Switch the “Mixed” on the back to ON. This allows to mix the RX1 and RX2

signals to RX1’s 6.3mm non-balance output jack and then to a mixer or

amplier for volume control.

2.Connect the power

2.1. Connect the AC/DC adapter:

Check that the DC current and voltage ratings of the adapter match the

label on the unit. Connect the DC terminal to the “DC input” port on the unit,

and the AC end to an AC socket.

2.2. Set the parameters:

Turn the power on and set the parameters of receiver according to the

setting instructions.

Caution! Secure the power cable on the fastening hook of anti-pulling clip in order to prevent the power cable from falling.

The Mute button on the hand-held unit also triggers the power-on. That’s why the

unit is on as soon as the batteries are replaced. Therefore, if you do not wish to turn on

after changing the batteries, keep the Mute switch on mute.

1. Unscrew the outer tube of the transmitter (Figure 1).

2. Place 2 AA batteries in the battery holder while make sure they are in the correct polarities (Figure 2).

3. Screw the outer tube on (Figure 3).

4. To turn the unit on:

a. Push the power button to turn on (Figure 4a), or

b. Push the Mute switch up also to turn the unit on (Figure 4b).

5. Set the transmitter parameters according to the instructions.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction, may cause harmful interference to radio communication. However, there is no grantee that interference will not occur in a particular installation. If this equipment dose cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on , the user is encouraged to try to correct the interference by one or more of the following measures:

--Reorient or relocate the receiving antenna.

--Increase the separation between the equipment and receiver.

--Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

--Consult the dealer or an experienced radio/TV technician for help.

Notice: The changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, no change to the antenna or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void user’s authority to operate the device.

CONSUMER ALERT

This particular wireless microphone device operates in portions of the 617-652 MHz or 663-698 MHz frequencies. Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies.
