RECHARGEABLE BATTERY GUIDE

Tips - To Prolong the Life of Rechargeable Batteries

Always charge the batteries before first and after use.

Always store portable system with batteries in a fully charged condition.

Always power off the portable system and transmitter/mic when NOT in use.

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 months. Battery may not charge if not charged for

a prolonged periods of time.

Store in dry, cool place away from heat. Elevated temperature reduces longevity.

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

rechargeable sealed lead-acid (gel cell) batteries.

FAQ - PORTABLE PA

Q: Why is my MA-808 not recharging (battery meter is not flashing)?

A: Plug one end of the included AC cord into the 12 AC Input Socket and the other end into an AC

outlet. Normal charging starts once indicators in the battery meter is flashing.

A: The built-in rechargeable batteries life has ended. Replaced with new, fresh charged batteries.

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 2~3pm (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, VCR, DVD players. As well, modular CD

players can be inserted into most models.

Q: How to Charge the Battery?

A: Simply plug the AC power cord into an AC outlet. “Flashing” LED indicators are flashing up-and-

down to denote normal charging status. 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, MA-101A &

MA-101B) or one indicator remaining in battery meter (MA-100, MA-202, MA-202B, MA-303, MA-505

, MA-708, MA-808). Plug into an AC outlet to re-charge immediatley.

Q: Average Life Span of Sealed Lead-Acid Rechargeable Battery?

A: The batteries should have a life of approx. 2~3 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 2~3 years or more.

Q: Should batteries be kept in the handheld or bodypack transmitters when not in use?

A: Do not leave old batteries in the transmitters if it will not be used for a long time. Batteries could

leak or corrode and damage the internal PCB of the transmitters.
