Disposal
Dispose of any unusable devices or batteries responsibly and in
accordance with any applicable regulations.
Disposing of used batteries with domestic waste is to be avoided!
2005-08-13
Batteries / NiCad cells often contain heavy metals such as
cadmium(Cd), mercury(Hg) and lead(Pb) that makes them
unsuitable for disposal with domestic waste. You may return
spent batteries/ accumulators free of charge to recycling centres
or anywhere else batteries/accumulators are sold.
By doing so, you contribute to the conservation of our environment!

One wireless microphone can simultaneously transmit to multiple MA-202 units
receiving on the same frequency for a wider and expanded coverage.
Multiple wireless microphones of the same frequency cannot transmit to an MA-202
receiver on that same frequency. For example, if you have both a hand-held wireless
microphone and a body-pack transmitter on the same frequency, be sure to switch off
one of the two to avoid severe interference between them!

Charging begins immediately, and will be indicated by a flashing LEDs. If the LEDs are
not flashing, it may due to excessive power over-drain and it may take longer for the
LEDs to flash. This is normal and not faulty. If, after a while, there is still no flashing
LEDs, the rechargeable battery may be faulty.
If a battery replacement is needed, open the battery compartment and exchange the
faulty battery for a new one. Be sure to insert the battery with the right polarity
connection.
26
Shoulder Carrying: Remove the shoulder belt 8 from the Battery Compartment 26 and
hook the connector around the rod on top of the unit, between the Fixed Handle and the
Speaker.
Simply plug the connector of the supplied DC adapter to the DC 18V Power Input Jack
,17 and plug the other end into any available AC socket.
Battery will re-charge itself once plugged-in regardless if the system is turned on or
off.
and adjust volume as desired.
Hand Carrying: Remove the shoulder belt 8 and store in the Battery Compartment
directly above the battery. Use the Fixed Handle for transport.
Please make sure the built-in rechargeable batteries are fully charged before and after
use. The battery itself will gradually self-discharge over a long period of time.
Therefore, if the system will not be used for a long period of time, please make sure
the batteries are fully charged before storing them properly. The Company warranty
DOES NOT applies to over-discharged batteries; hence, please ensure the batteries are
recharged every 3 months.

With proper care and charging, it is unlikely that it will be necessary to replace the MA202 battery for some time. However, there is an access panel provided for this purpose.
If extended periods of use are required without time to recharge the battery, you may
wish to have a second battery fully charged and ready to install and use once the existing
one is drained. The rechargeable battery is a standard 12V/2.9A gel cell or 14.8V/3A

Q:
Average Life Span of Sealed Lead-Acid Rechargeable Battery?
A:
The batteries should have a life of approx. 2 years if used and maintained properly. Battery life is
determined by temperature, depth and rate of discharge, and the number of charges and
