Notes:
!
MA-100 uses a CR2032 lithium 3.0V coin battery that is commonly used in small electronic devices. You'll find these batteries at most electronics and drug stores.
!
!
Remote control operates on an infrared (IR)-based technology. If it has an unobstructed line-of-sight, the remote control can function at distances of up to 5 meters (about 17 feet).
Dispose of the used battery according to local environmental laws and guidelines.

REPLACING THE RECHARGEABLE BATTERY
With a proper care and charging, it is unlikely that the rechargeable battery needs to be replaced by a new battery for some time. You may consider to have a backup battery in case you need to use MA-303 for a longer time. The rechargeable lithium battery is available from MIPRO.
!
!
!
!
!
!
INSTRUCTION OF CHARGING THE RECHARGEABLE BATTERY
Charge the battery completely in its first use to obtain its maximum capacity.
Connect to any available AC power outlet using the included DC adapter to the DC
IN jack .
The battery meter LED blinks while charging. Blinking LED may start later if the battery suffers from excessive battery drain. The battery may be damaged if the
LED does not blink after charging for a while.
+
The battery is low when only the red LED is on. Please recharge the batter for at least 4 hours (the time of charging depends on the type of battery).
+
All LED blinking means the battery is charging.
+
Charging completes when all LED are on.
Fully charge the battery after each use or minimum once every 3 months.
Improper maintenance or over discharge the battery will not be covered by the warranty.
The battery stops charging when it is fully charged. It is safe to leave it connected to the power overnight.
Note:
!
The rechargeable battery pack is user replaceable. Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. Battery life and number of charge cycles vary by use and settings.
Personal Wireless Public Address System
Steps of Changing the Rechargeable Battery
!
Lay the PA system on a flat surface. Power off and gently remove USB from USB port, if needed.
!
Remove the two screws so the battery cover can be opened and removed.
!
The battery pack is stored inside the compartment slot. Pull out the battery gently and remove it completely by detaching the connecting pins.
!
Insert the replacement battery pack. Ascertain the connecting pins are connected firmly before inserting. Carefully slide the battery back into the compartment slot.
!
Insert back the two screws back in place securely.
Warning:
!
Never short-circuit the battery pack by either accidentally or intentionally bringing the battery terminals in contact with another conductive object. Never expose a battery pack to abnormal shock, vibration or pressure. Failure to observe the foregoing could result in serious injury.
Note:
!
Dispose of the used battery according to local environmental laws and guidelines.

Wireless Mic System
!
!
Turn on master Power/MIC VOL switch . Power indicator glows red. Ready for operation.
Turn on CH 1 VOL or CH 2 VOL VOL switch.
Turn transmitter power on. Ensure fresh alkaline or lithium batteries (not included) are installed.
RF indicator or glows green after the transmitter is turned on to denote a successful RF link.
Adjust CH 1 VOL or CH 2 VOL to desired volume.
Ensure receiver and transmitter have the same matching operating channels.
(see page 17: Corresponding Channel Display: MA-303 Receiver and Transmitter)
If not, perform ACT Synchronization (Sync) between Receiver and Transmitter
Channels (see page 18 ).
Notes:
!
Same wireless microphone can transmit to multiple MA-303 systems on the same channel for a wider and expanded coverage.
!
It is not possible to transmit two wireless microphones on the same channel to MA-
303 system. Only one transmitter can be used at a time on that channel. Be sure to turn off one of the two transmitters to avoid interference.

FAQ - PORTABLE PA
Q: How to adjust for optimal sound volume?
A: If the portable system has both Master & Microphone volumes, we recommend turning the Master volume to about 3pm (clockwise) first and about 1~2pm
(clockwise) for Microphone or other volumes.
Q: How to prevent and minimize the annoying feedback?
A1: Do not stand directly in front of the speakers; keep mics away from speakers.
A2: Avoid pointing microphone towards the speakers.
A3: The microphones should be behind the speakers wherever possible.
A4: Locate the portable PA between the crowd and the presenters and facing the crowd.
A5: Turn down the sound level coming out of the portable PA / speakers if necessary.
A6: Place the speakers above the head of the crowd.
Q: What if I need more power to cover a larger crowd?
A: Two or more portables can be used with one wireless microphone transmitter.
Ascertain that the receiver frequency in each portable coincides with the wireless microphone.
Q: Can I play music through the systems?
A: Yes. All MIPRO portables have auxiliary inputs (3.5mm min-jack, RCA or
1/4”phone), which will accept input from an external iPod, MP3, CD, cassette,

FAQ - RECHARGEABLE BATTERY
Q: How to Charge the Battery?
A: Simply plug into a power outlet using the included power cable and adapter.
“Flashing” LED indicates it is charging. The main power switch can be on or off position during charging. Microphones or music can be used during charging & power is on.
Q: How to Spot System Low Battery?
A: When Power LED is lit (MA-705 & MA-707) or Charge LED is lit (MA-101& MA-
101a) or one indicator remaining in battery meter (MA-100, MA-202, MA-303, MA-
708, MA-808). Plug into a power outlet to re-charge ASAP.
Q: Average Life Span of Rechargeable Lithium or Sealed Lead-Acid Battery?
A: The batteries should have a life of up to 2 years if used and maintained properly.
Battery life is determined by temperature, depth and rate of discharge, and the number of charges and discharges (called cycles).
Q: When to Replace the Battery?
A1: Power LED indicator is not “lit” when power on. (No battery voltage).
A2: LED indicator or meter is not “flashing” when plugged-in.
A3: Getting 1~2 hours operating time per charge.
A4: When battery has been used extensively for 2 years or more.

RECHARGEABLE BATTERY GUIDE
Tips - To Prolong the Life of Rechargeable Batteries
Power off the portable system and transmitter/mic when NOT in use.
Store portable system with batteries in a fully charged condition.
Most lithium-ion polymer batteries use a fast charge to charge your device to
80% battery capacity, then switch to trickle charging. That's about two hours of charge time to power up to 80% capacity, then another two hours to fully charge it, if you are not using the portable PA system while charging.
The battery prefers a partial rather than a full discharge. A partial discharge reduces stress and prolongs battery life.
Avoid frequent full discharges because this puts additional strain on the battery.
Several partial discharges with frequent recharges are better for lithium-ion than one deep one.
Avoid keeping the battery at full charge and high temperature.
It is OK to leave the system plugged into a power outlet when not being used for a long time. The built-in automatic protection circuitry will auto shut-off when fully charged. It will not harm the system or the battery.
Fully charge the system at least once every 3~6 months. Battery may not charge if not charged for a prolonged periods of time.
Do not freeze the battery. Store in dry, cool place away from heat. Elevated temperature reduces battery lifespan.
Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. Battery life and number of charge cycles vary by use and settings.
CAUTION: DO NOT recharge other types of batteries and connect a battery's negative terminal to another batteries positive terminal. An explosion and/or a fire could occur as a result. Use only authorized rechargeable lithium batteries.
