1. Power On
. Minimize all volume levels before turning on the Master Power Switch A fully lit
Battery Status Indicators indicates the rechargeable battery is fully charged A single
red color indicator indicates the rechargeable battery is low on power. Simply plug the
supplied power cord into the power socket on the back and the other end into an AC
power outlet to recharge the battery.

2. Master Volume Control
(A) Master Volume Control has two switchable modes The standard mode resets to
zero volume level after power is turned off. The memory mode saves and recalls the
last programmed volume level by pressing and holding the specific volume indicator
before power is turned off.
(B) We recommend the master volume control is turned to the maximum level. Next,
adjust volume of other audio input individually to avoid distortion with maximum
dynamic range output. Built-it audio limiter serves automatically to pre
level from exceeding a preset limit and stop sound from distorting.

meter indicators will glow immediately no matter if the power switch is on or off
This means that the built in switching power supply is functioning normally and the
built in rechargeable batteries are fully charged If the battery meter indicators are
blinking this means that the built in switching power supply is working normally and
the built in rechargeable batteries are in an under charged condition After a couple
of minutes the battery meter indicators will stop blinking and continue a glowing
condition indicating the batteries are now fully charged

2. How to use DC power input
(A) Two built in series connection lead-acid batteries with models WP 4.5-12 are used.
-
When the batteries are fully charged, the unit can be operated continuously for
approximately 7 hours in standby mode (CD player and two receivers are turned on);
5~6 hours for audio and 3~5 hours for music The above figures are references for
brand new batteries only
(B) The built in rechargeable batteries can be recharged when the unit is plugged into an
AC or DC power outlet
(C) In the case of no AC power connection if the power switch is not turned on the
battery meter indicators will not be shining When the power switch is turned on
the red LED on it will be shining; meanwhile, if 2 to 4 battery meter indicators are
shining, it means the battery power is enough for normal operation The number of
the shining indicators is in direct proportion of the battery power If only battery
meter indicator is shining or the red LED on the power switch is sparking it means
the battery power is insufficient and immediate charge is necessary If no battery
meter indicators are shining after the power switch is turned on it means the
batteries are completely discharged or possibly faulty

the usage time to preserve battery life
temperature is too high, resulting in excessive discharge and charging failure the first
step is to remove the battery and charge it by V A DC power supply for more
than half an hour and noted the battery surface temperature should not exceed 50
during charging. Then reload it into the machine and turn on the power if the battery

Ⅹ. Helpful Operating Tips
1. We recommend placing sound system between the target audience and the
presenter, facing the audience and raised above their heads using a
speaker stand or tabletop. This set-up helps prevent the annoying feedback
by keeping wireless & wired microphone users behind the sound system.
The internal power supply rechargeable batteries should be kept fully
charged. Always charge the system after use.
2. Minimized the master volume control before powering on. Adjust the
volume controls afterward.
3. Each audio input is accepted through amplifier and its volume can be
controlled separately.
4. Each audio input can be broadcasted and recorded at the same time.
5. NEVER place any wired or wireless microphone in front or close in front of
the speaker otherwise feedback could occur.
6. Do not expose the MA-708 to an environment where there are water
dropping or splashing.
7. This speaker fits into a standard speaker tripod stand.
8. Detached the power cord from AC power outlet once the system is fullyrecharged.
9. Refer to operating instructions for wireless microphone system.
10. Refer to actual product in the event of product description discrepancy.
11. Frequency range, output power and maximum deviation to comply with the
regulations of different countries.
