Maintenance-free Lead Acid battery
Guidelines for maintenance-free Batteries:
1. Battery should operate at temperatures between 15°C ~ 50°C. To ensure a longer life span, it
should be kept between 5°C ~ 35°C. For optimum result, 20°C ~ 25°C will be ideal. When
temperature falls 15 degrees below zero, battery will undergo some changes in its chemical
contents and therefore cannot be recharged. Operating the battery at higher temperature will
result in higher capacity but shorter lifespan, whereas lower temperatures operation has a
longer lifespan but less capacity.
2. If the battery is not recharged 72 hrs after it is completely used, it will be permanently damaged.
3. When the battery is being charged, the internal gases will be electrolyzed into water at the
negative charge, maintaining the battery’s storage abilities with no water added. However,
erosion at the charged ends of the battery will cause poor performance.
4. The battery’s cycle lifespan ( no. of charge and discharge cycle ) is determined by the degree at
which power is dissipated., especially the degree of discharged each time it is used and the
recovery charging method. For normal use, the battery can be used for longer hours when less
power is dissipated each time and vice versa. At 25°C, maintenance-free batteries could be
charged 150 ~ 200 times at 100% discharge each time.
5. Decrease in capacity, internal short circuit, deformation in appearance, erosion of charged ends
and decrease in open circuit voltage are symbols indicating battery is approaching the end of its
life cycle.
6. When two batteries are used in parallel connection, the resistance of the cables should be kept
equal.
Properties of the Lead Acid Battery:
1. Has no memory effect. Can be charged at anytime, even when the recharge indication light is
not on.
2 .Performance and efficiency are affected by changes in the environment, especially temperature
and humidity. (Best operated between 20°C ~ 25°C)
3. Battery discharge naturally according to a certain pattern even not in use. For best performance
and a prolonged lifespan, it should be recharged every month even when not in use.
4. Under normal circumstances, battery could last for about a year.
5. When the battery’s life expires, possible indicators include internal short-circuit, decrease in
capacity, deformation in appearance, erosion of charged ends and decrease in operating
voltage.
User’s Precautions:
1. For first-time use, charge the battery for 10 hrs until it is fully charged.
2. To maintain performance and lifespan, if product has not been used for 3 months after the
initial shipment, please fully charge the battery.
3. Before each use, it’s advisable to charge the battery to its full capacity.
4. The average lifespan of the battery is one year. The user is advised to change the battery after
one year of use.
5. The current consumption is in direct ratio with load current. The more current consumption, the
less the operation time.
Remark:
The removal of the battery/ies must be done by an experienced qualified technician or by the appropriate recycling operator!

Caution and tips on how to obtain the best results.
1. Before inserting the batteries, please make sure that they are inserted according to the correct polarity.
2. The audio cable of VHF transmitters also serves as antenna. The length of the cable is cut according to the specific frequency range. Do not alter the length or mix around the cable of different transmitters. The use of wrong audio cable will affect the antenna efficiency of the transmitter!
3. Use only brand new Alkaline batteries. Do not use " general purpose " batteries, When batteries are weak, replace all the batteries at the same time. Do not mix and use new and old batteries together.
4. Position the receiver such that it has the least possible obstructions between it and the transmitter. Line of sight is best !
5.The transmitter and the receiver should be as close as possible but not less than 1m.
6. A receiver cannot receive signals from two or more transmitters simultaneously.
7. Turn the transmitter off when it is not in use. Remove the batteries if it is not to be used for a period of time.
8. Antennas form an integral part of the receiver and must be installed when in Operation.
Simple DIY Trouble-shooting :
No sound when one speaks into the wireless microphone
Please verify the followings:
1.Main power switch of the system should be ON. When power on LED not lighting up, it means that the battery is either weak or not charged. Please plug in the AC cable to
Charge the battery. The rechargeable battery has a life span of about 2 years. If the batteries have reached their life expectancy, please change to a fresh pair.
2.The power switch of the corresponding receiver module should be put to ON. This is indicated by the lighted power LED. When two wireless microphones are used, both power switches of the receiver modules must be ON.
3.Wireless microphone should be switched to ON and verify that the battery is okay. ( please refer to wireless microphone operating manual ).
4.Please verify that the frequency on the wireless microphone and the corresponding built-in wireless receiver module are exactly of the same frequency group and channel.
5.Master volume control of the system should be turned on.

Operating procedures
After unpacking the unit for the first time, please charge the unit for about 4~5 hours before any operation. This is absolutely necessary as the built-in rechargeable battery might have been discharged naturally due to long shipment and storage time, even though it has been fully charged in the factory prior to shipment.
To charge the battery, just plug in the DC end of the switch mode power supply into the
DC IN of the unit and charging will start automatically. During the charging process, the charging indicator LED will flash GREEN. When GREEN LED stays glow permanently, battery is then fully charged and normal operation could now be started.
To operate this portable sound unit, switch on the main POWER switch (H), which will glow GREEN. However, the main POWER switch does NOT switch on the WR modules as each of them has dedicated Power / Volume control switch indicated by WR1, WR2.
To operate each of them, you must switch them on accordingly.
When the Charging / Battery Status Indicator glows RED, it means the builtin rechargeable battery is weak and a recharge is necessary. While charging, the unit could also be operated simultaneously.
Operating the built-in Wireless ( WR ) receiver modules
In the SMART 300 control panel, there are two designated power switch / volume control knob for the built-in Wireless Receiver (WR). They are indicated by WR1 and
WR2 .
st
To use the 1 wireless microphone, first switch on the main power switch (H), then switch on the WR1 power / volume control switch, Red LED next to it will glow. Switch on the corresponding transmitter ( RF ). Rotate the volume control knob clockwise and amplified sound could be heard if voice is spoken into the transmitter. nd
To use the 2 wireless microphone, switch on WR2 power / volume control switch and repeat the same operation as above.
By default, when the system is equipped with one WR receiver module only, it is always controlled via WR1 switch, WR2 is then redundant.
For SMART 300 which comes with wireless receiver (WR) module, there are two possibilities, namely the VHF or UHF version. The VHF receiver module is a fixed frequency type. To operate the VHF version, just switch on the corresponding wireless microphone(s) after switching on the WR1 or WR2 switch.
To operate the UHF version, which comes with 16 preset frequencies, please ensure that the channel setting on the wireless microphone and SMART 300 receiver module(
D or E ) are the same before operation. Then perform the same procedure as above.
The above operation is only valid with SMART 300 version with built-in wireless receiver (WR) module(s). Otherwise, the WR controls are redundant.
