SMART 300 Operation Manual
Congratulation and thank you for the purchase of this all-in-one ultra compact
portable sound system.
To ensure a trouble-free operation, please read this manual thoroughly to fully
understand its controls and functions.
There are various versions of the SMART 300 as follow :
1. SMART 300 Passive Speaker. (Fig.1)
2. SMART 300 portable sound system only ( VHF / UHF ) ( Fig.2 )
3. SMART 300 with USB Digital player. ( VHF / UHF ) ( Fig.3 )
All the versions can be equipped with 1 or 2 Wireless ( WR ) receiver module(s). The
wireless (WR) receiver module can be either VHF or UHF. The VHF module is a fixed
crystal single frequency type whereas the UHF module is a PLL synthesized type
with 16 preset frequencies ( identified by external 16 channel rotary switch(s) ).
Remark: It is also possible to have all the above versions without any wireless (WR)
fitted.
Configuration :
All versions of SMART 300 series comes equipped with the following :
1.A switch mode power supply.
2.One or two wireless microphones, either handheld or bodypack transmitter.
( except version with no wireless receiver module built-in )
.
Matching Transmitters
Optional accessories :
1.Carrying bag.
2.Tripod stand.
3.Charger for UHF transmitter.
4.Companion powered speaker.
5.Wired microphone.
Remark:
Manufacturer reserves the rights to change the above combinations
without prior notice.

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.
6. SMART and FOCUS operate on one 12V/2.7AH battery. ADVENTURE, CHALLENGER, and
VICTORY operate on two 12V/4.5AH batteries.
