wired microphone, switch to MT position and the
gain control can serve as input sensitivity adjustor.
9. Battery Compartment and Cover: Accommodates
two 1.5V(AA) batteries.
10. Detachable Belt Clip: Allows 360 degrees rotating to
suit transmitting angles. To detach simply use a

1. To adjust GT/MT Switch (9), and Gain Control (7),
simply push down both snap locks on the sides of
battery cover and flip it backwards to expose the
adjustment panel.
2. The LED indicator flashes briefly when power on
indicating normal battery status. If no flash occurs it
has either no battery, the battery is drained or installed
incorrectly. Change accordingly.
3. Plug the microphone connector into the input jack and
tighten the connector screw clockwise direction as
shown in (Fig. 2).

4. FUNCTIONS OF LCD DISPLAY
1. ERR Message: When "ERR" appears, it means
"Operation Error". 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 are about to program into
the system exceeds microphone's upper limit.
(At this time, microphone is still operatable
and the frequency remains unchanged. To
clear the "ERR" message in LCD display,
simply turn off the power and switch back
ERR no04→The frequency you are about to program into
the system is below microphone's frequency
lower limit. (At this time, microphone is still
operatable and the frequency remains
unchanged. To clear the "ERR" message in
LCD display, simply turn off the power and
switch back on.)
2. "Group" & "Channel " : When both items are shown,
they indicate that the user is currently using the pre-
programmed frequency in the receiver.
3. "Channel" Only : If "Channel" is the only item shown in
the display, it indicates the user is using the
personalized frequency. (Such frequency can only be
programmed via MIPRO's ACT Software and available
on ACT-707MC only.)

1. Pushing down both snap locks on the sides of battery
cover to open battery cover. Take out the batteries.
Fig.(3).
2. Insert two 1.5(AA) batteries into the battery
compartment according to the correct polarity as
shown in Fig. (4). Then push up to close the battery
compartment as shown in Fig. (4).

4. Battery Status:
Battery Status: When the battery has less than 10%
power remaining, batteries must be replaced. If
undervoltage continues, LCD will show "PoFF" and shut
down the system to avoid battery being over-discharged.
5. Switch Off:
When switch the power knob to "Off" position, LCD
will show "PoFF" first. Then, the system is completely
shut down and no further message will be displayed.

PS: When the microphone is not in use:
Make sure the power of the microphone is off. If the
microphone will not be used for some time, please
remove the batteries from the battery compartment to
avoid battery leakage and result in damaged battery
springs and circuit. If a rechargeable battery was
used, take it out and recharge it.
