11. Only use attachments/accessories specied by the manufacturer.
12. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparatus. When a cart or rack is used, use caution when moving the cart and apparatus combination to
avoid injury from tip-over.
13. Unplug the apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualied personnel. Servicing is required when the apparatus has been damaged in
any way including but not limited to power supply cord or plug damage, liquid ingress, foreign objects in
the chassis, exposure to rain/moisture or impact damage. In addition the unit must be serviced when you
experience any abnormal operation.
15. CAUTION: These servicing instructions are for use by qualified service personnel only. To reduce the
risk of electric shock, do not attempt to perform any servicing other than that contained in the operating
instructions unless you are qualied to do so. In addition opening the casing will result in your warranty
becoming null and void.
16. Do not install this apparatus in a confined space such as a book case or similar unit. Good ventilation
should be maintained around the apparatus and any vents, air-inlets or fans should not be obstructed by
objects such as paper, table-cloths, curtains etc.
17. WARNING: To reduce the risk of re or electric shock, do not expose the apparatus to rain or moisture. The
apparatus should not be exposed to dripping or splashing and objects lled with liquids, such as vases,
should not be placed on the apparatus.

22. Warning: People who are implanted with an electronic cardiac pacemaker or AICD device (Automated
Implantable Cardioverter Debrillator) should pay attention to the following items:
Any radiation source may cause interference to the normal function of this kind of implanted devices. The
output power of all the wireless microphones’ transmitters normally is very low (less than 0.05W). And
usually it will not cause any disorder, especially when the wireless microphones are several inches away
from the implanted devices. When the RF is powered off, all the possible interference will be stopped. If
you are disturbed with any problems when using this system or any other RF devices, please consult your
doctor or your medical device dealer.
Attention: To ensure its optimal quality and also to comply with the related statutory rules, the inner circuits of
the receivers have been adjusted accurately. Please do not attempt to open or disassemble the receivers and
transmitters. It may invalidate your warranty and even may cause malfunctions.

11. Battery Charge Status/Battery Empty
i. Normal operating status
The full battery LED indicates the battery inside EZGO is fully charged and will last 6-8 hours.
When the low battery LED is displayed and ashes, it indicates the battery will last 15 minutes
or less. EZGO will power off when the battery is exhausted. Recharge the battery for continued
portable use.
Caution: When the low battery LED is flashing, please turn Power/Volume knob to "OFF"
and recharge the battery as soon as you can, or you can plug in the external power supply
immediately.
The Battery Empty LED indicates either a battery is not installed or if it is installed there
may be a problem with it. If a battery is installed and the Battery Empty LED is illuminated
check to make sure the connecting wires are secure and the battery is not damaged. If it is a
replacement battery check to make sure it is qualied.
ii. Charging status
When connected to mains, EZGO will immediately enter charging status. After 5 minutes the
remaining charging time can be estimated as follows:
a. If 3 Battery Charge Status LEDs are ashing in turn, 6-8 hours are needed for the
battery to be fully charged.
b. If 2 Battery Charge Status LEDs (Full and Half battery LED) are ashing in turn,
15 minutes to 4 hours are needed for the battery to fully charged.
c. If there is only one Battery Charge Status LED (Full) displayed and it is non-
ashing, the battery is fully charged and EZGO can be normally used
and operated.
12. External Power
When EZGO is connected to an external DC or AC power supply, the “External Power” LED
illuminates.
Battery is installed here.

Caution: Danger of explosion if battery is incorrectly replaced. Replace only with the same or
equivalent type. Contact the service centre to ask for the help on this replacement.

2. Remote control infrared receiver
This sensor receives signals from the accessory remote control. Do not place anything in front of
the sensor.
3. Display
The display shows if there is a drive inserted in the USB Drive input, what les are on the drive,
what operation the unit is performing, which track is playing, the lapse of time and the number of
total tracks.
4. STOP
Press to stop playing or to go back to the upper level of folders.
5. PLAY/PAUSE
Press to play or pause while in track mode. Press to enter a selected folder when in folder mode.
6. Previous Track/Fast Reverse
Press to go to the previous track while playing or the previous track in the track list. Press and hold
for fast reverse.
7. Next Track/Fast Forward
Press to go to the next track while playing or the next track in the track list. Press and hold for fast
forward.
*The USB Module buttons (Stop, Play/Pause, Fast Reverse/Previous Track, Fast Forward/Next
Track) and the remote control are only functional when the unit is operating from the “USB Drive”.
When a device is connected to the “USB to PC”, that device will control these operations.
8. USB Drive
Supports MP3/WMA le playback
9. USB to PC
The USB connector enables computers with USB connectivity to interface directly with EZGO for
full duplex recording and playback. You may use a USB A Male to USB B Male cable to connect
between a PC and EZGO.
In recent years the introduction of USB connectivity has ushered in a new appreciation of computer
audio capabilities helping to fuse digital with analogue and opening up endless possibilities for
recording musicians. The internal AD (Analogue to Digital) and DA (Digital to Analogue) converters
are 16-bit/48KHz enabling recording and playback above CD quality This ensures the recordings
you make with a Wharfedale Pro Connect Mixer will have outstanding quality. EZGO is fully class
compliant and requires no drivers when used with modern operating systems. Mac OSX, Windows
XP, Vista and 7 require no additional driver software to function with EZGO.

Interferenceandsignaldisturbances
Cause/Solution
- Connect the power cable to the AC inlet / DC Jack
- If the power cable is not connected, make sure the battery has been charged
- Make sure that both the “USB Input Level” knob and “Wireless Mic Level” knobs
are turned on.
- Make sure the les inside the USB drive are in MP3 and WMA format
- Make sure the remote control is within operating range
- The battery is dead and the remote control needs to be replaced
- Check that the transmitter and receiver are on the same channel
- Make sure the wireless mic is within operating range
- Check the power level of the microphone batteries.
- When two transmitters are being used, select different frequencies. If voice
disturbance still occurs, try selecting another channel until interference is gone.
- Make sure there are no other wireless systems operating on the same
frequencies in the area. This includes other wireless microphones, television or
radio stations, etc. Try setting the transmitter and receiver to a new channel
