• Before connecting to power, make sure the voltage marked on equipment is the same as that on the power socket.
• Do not place the machine at a place where high temperature and humidity are expected.
• Do not operate the system with wet hands.
• Keep the machine away from any heat or ignition source.
• Before setting up the machine, make sure that the volume is set at the minimum for both the mixer and amplifier.
• Caution: The suitable environment for this product is with a temperature between -10°C (14°F) and +50°C (122°F).

| FEATURES

• CSU4000 is designed with FBT newest wireless and conferencing technology. It provides maximized compatible channels with a given bandwidth. Built in logic circuit provides conferencing feature. A microphone assigned with priority will work as a chairman unit. It overrides other microphones. Logic setting of one CSU4000 receivers can be cascaded. A microphone with priority in one receiver will also have priority in a cascaded system. The patented REMOSET® synchronizes all four microphones simultaneously by push one button.
• The microphone is of 108 MHz bandwidth(MAX). This feature allows more attendants to join the conference.
• Antenna outputs and AC power supply are designed to be cascaded.

| CONNECTING THE RECEIVER

1. Connect the audio signal cable

Connect the CSU4000 audio output to a mixer or an amplifier: Audio cable: one end of the XLR or ∅6.3mm audio cable is connected to the "AF output balanced" of CSU4000 and the other to the audio input of the mixer or amplifier.

2. Connect the power

Connect AC power cable: insert one end to the receiver's AC jack and the other to AC power outlet (100\~240VAC).

Cascading of AC power cable and antennas

*Up to 10 units can be cascaded for power/antenna.

When the microphone channel is turned on, the control signal corresponding to this channel will continue to output “High” (+5Vdc). When turned off, the control signal output of this channel will be “Low” (0V). The logic control signals can be used to trigger other applications, such as: the video camera.

INSTALLING TRANSMITTER // CST4000

   (1) The "frequency range labels" on "both" the receiver and transmitter are the same;
   (2)"Pairing" in the function menu of the transmitter is "activated;"
   (3) The "Device ID" on the transmitter is the same as that on the receiver; and
   (4) Transmitter battery is low (synchronization is impossible when battery is low).

*It should be avoided to have two or more receivers on REMOSET when REMOSET is used, as sometimes it prevents pairing due to the mutual interference of REMOSET signals.

1. Pairing 4 microphones simultaneously: Push [REMOSET] and the blue indicator starts to flashing. On the display all 4 receiver channels show "Synchronizing," indicating that data are being transmitted to all 4 microphones.

| ALERT FUCTION

The alert screen will blink slowly under these circumstance:

1. When microphone is under mute mode.
2. When microphone's power is OFF.
3. When microphone's battery level is too low.

NOTES FOR THE PRODUCT

1. For the optimized reception, keep the receiver 3m or more away from the transmitter.
2. Receivers and transmitters shall be kept at least 50cm away from any metal object.
3. Do not point the receiver directly into a speaker or there will be annoying feedback noises.
4. It is recommended to hold the transmitter (microphone) at the middle section for the optimized audio pickup.
5. In case that the microphone is not used for an extended period of time, it is recommended to remove the batteries from the battery bay in order to prevent electrolyte leaks from damaging the transmitter.
6. When changing the batteries, it is recommended to change both batteries of the same manufacturer for the optimized power performance.

IMPORTANT NOTE

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