Li-Ion Battery Safety Precautions (sample document)
1. When Using the Battery
Danger
(1) Misusing the battery may cause the battery to get hot, explode,
or ignite and cause DANGER serious injury.
Be sure to follow the safety rules listed below:
.Do not place the battery in fire or heat the battery.
.Do not install the battery backwards so that the polarity is revers
ed.
.Do not connect the positive terminal and the negative terminal of
the battery to each other with any metal object (such as
wire).
.Do not carry or store the batteries together with necklaces, hairpi
ns, or other metal objects.
.Do not penetrate the battery with nails, strike the battery with a h
ammer, step on the battery, or otherwise subject it to stro

s safety and protection devices which, if damaged, may c
ause the battery to generate heat, explode or ignite.
(3) Do not place the battery on or near fires, stoves, or other high-
temperature locations. Do not place the battery in direct s
unshine, or use or store the battery inside cars in hot wea
ther. Doing so may cause the battery to generate heat, ex
plode, or ignite. Using the battery in this manner may als
o result in a loss of performance and a shortened life exp
ectancy.

TROUBLESHOOTING
Problems Check Points
No reception
- Check the battery status
- Check the connection and cables
- Check the communication range
Poor reception,
static, noise
- Change the location of RX Set
- Check the communication range
- Check to see if unit is placed near TV,

2. While Charging
Caution
The temperature range over which the battery can be ch
arged is 10°C to 45°C. Charging the battery at te
mperatures outside of this range may cause the
battery to become hot or to break. Charging the
battery outside of this temperature range may al
so harm the performance of the battery or reduc
e the battery’s expectancy.
3. When Discharging the Battery
Danger
Do not discharge the battery using any device except for
the specified device. When the battery is used in
devices aside from the specified device it may d
amage the performance of the battery or reduce
its life expectancy, and if the device causes an a
bnormal current to flow, it may cause the battery
to become hot, explode, or ignite and cause seri
ous injury.
