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.

Battery

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.

*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.
