FeaturesContents

Bandwidth to 72MHz for compatibility with the

wideband receivers.

Industry's smallest bodypack transmitter with

sturdy magnesium alloy housing for 2AA batteries.

Antenna, mute button and XLR input connector

are located on the top of transmitter.

Backlit LCD displays working band-code, group,

channel, frequency, AF input gain, RF output power, mute, battery status, and error codes.

Innovatively designed battery cover allows easy

access to operate buttons and prevents accidental operation.

Mute button and remote-control jack is equipped

for easy activation of mute function.

High efficiency, low power consumption, low

spurious emission and high stability PLL synthesized circuit is applied.

An interference-free working channel can be

synchronized quickly and precisely by MIPRO's patented ACT™ function.

High SPL input without distortion.

Can be directly matched to high-low input

impedance for microphone and guitar without switching and the input sensitivity is adjustable.

Mini-XLR input connector for quick-lock or screw-

lock with lavaliere or headworn microphones and guitar.

Adjustable belt clip allows wearing transmitter in

any position.

Battery Status

! Indicates the power remaining in the transmitter

battery. When the battery has less than 10% power remaining it must be replaced or recharged. If an under voltage condition continues, the LCD will show “OFF...” and the system will shut down to prevent being overly discharged.

10 0% 80 % 60 % 40 % 20 % 10 %

Power Button

! Press and hold for 2 seconds to power on & off.

“OFF...” - Power Off

! When the power switch is turned off, the LCD will

show “OFF...” (for Power Off) first and then the system will shut down and no further messages will be displayed.

ERR Message

! When “ERR” appears in the display it indicates

that an operational error has occurred. Please refer to the following codes to diagnose which error you are experiencing.

ERR no01 EEPROM is not being programmed or internal

data error.

ERR no02 For testing only.

ERR no03 The frequency you want to program is above

the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed "ERR" message, switch the handheld transmitter off and on again.)

ERR no04 The frequency you want to program is below

the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed “ERR” message, switch the handheld transmitter off and on again.)

! “Group” & “Channel” : When both the group

and channel numbers are displayed, it means that you are using the pre-programmed frequency of the receiver.

! “Channel” Only : If “Channel” only is displayed,

it means that you are using a frequency which is not pre-programmed.

Disassemble the Belt Clip

! Turn the bodypack transmitter

to the back side like the right diagram.

! Pull open one side of the belt

clip and make it depart from the slot of the bodypack transmitter like the right diagram.

! Then the other side of the belt

clip can be departed from the other slot easily. The whole belt clip is departed from the bodypack transmitter completely like the right diagram.

Assemble the Belt Clip

! Turn the bodypack transmitter

to the back side. Put the belt clip to the right direction and aim the one side of the belt clip to the slot of the bodypack transmitter like the right diagram.

! For opposite wear of bodypack

transmitter, just rotate the belt clip by 180℃ like the right diagram.

! Put one side of the belt clip to

the slot of bodypack transmitter and fix it like the right diagram.

! Pull open the other side of the

belt clip and put it to the other slot of bodypack transmitter and fix it like the right diagram.
