3. A battery protection feature is provided with the IPD-4500 system, and when the "warning, needs
charging" red indicator light is on, it indicates that the system will enter the automatic shut-off mode and
needs to be charged before it can be restarted for use.
In this case the system may exhibit distorted
sound or abnormal functioning and the battery needs to be fully recharged before operating the IPD-4500.
The system should return to normal after charging.
4. When the IPD-4500 system is charging, the power level indicator light is green and flashes. When the
indicator light is green but does not flash anymore, this shows that there is sufficient power. In normal
conditions, it takes about 7 hours from
[red light] to
[green light] when the power switch is
set to the “ON” position, and it takes 4.5 hours to finish charging when the power switch is set to the
“OFF” position.
When using the NI-MH as the power supply, in normal use the duration of IPD-4500 continuous play
depends on the volume at which the music is played. At normal volume, it can be operated continuously
for over 8 hours.
5. If the internal rechargeable batteries cannot be recharged or the playing time is extremely short, it
indicates that the service life of the batteries have ended, and they need to be replaced with new
batteries. (Please refer to the battery replacement instructions.)
6. Due to the intrinsic limitations of rechargeable batteries, we would like to make users aware of the
following:
● Do not expose the batteries to heat or place them over an open flame. Otherwise, the batteries
will leak or explode.
● Do not disassemble the batteries. The alkaline liquid inside is highly corrosive and may cause
injury.
● Do not short-circuit the batteries.
● Do not place the batteries in a closed container.
● Do not swallow the batteries.
● Do not use the batteries with reversed polarities.
● Do not mix old and new batteries. In particular, do not mix with nickel-cadmium batteries, dry cell
batteries, etc.
● Do not use a battery if it is leaking, is deformed, or has other abnormalities.
● Do not place the batteries in water, which will affect their performance.
● If the main unit will not be used for a long time, remove the batteries from the main unit. During
long-term storage, charge and discharge the batteries once a month.
● Use the batteries after they are fully charged. Do not charge batteries at temperatures lower than
0
°
C or higher than 40
°
C. Do not charge or discharge batteries using current not of the specified
range.
● Keep the batteries away from infants and children. Do not let a child use the batteries unless he or
she understands how to use them correctly.
● If it is necessary to change two or more batteries at the same time, please fully charge all of the
batteries before use and store the batteries in a cool, dry place. Storage conditions: Batteries
should be stored in an environment with a temperature of 10-35
°
C and humidity
≤
80%. The
temperature for long-term storage (3 months or longer) should be 10-25
°
C.
● Do not forcefully strike, shake, or press the batteries.
