specified to charge it. Be sure to follow all instructions that
are provided with the battery charger.
Discontinue charging a battery that gives off extreme heat or
a burning odor.
Use the battery only in CHC equipment that is specified to
use it.
Use the battery only for its intended use and according to the
instructions in the product documentation.
WARNING –Do not damage the rechargeable Lithium-ion battery.
A damaged battery can cause an explosion or fire, and can result in
personal injury and/or property damage.
To prevent injury or damage:
Do not use or charge the battery if it appears to be damaged.
Signs of damage include, but are not limited to, discoloration,
warping, and leaking battery fluid.

Do not expose the battery to fire, high temperature, or direct
sunlight.
Do not immerse the battery in water.
Do not use or store the battery inside a vehicle under hot
weather condition.
Do not drop or puncture the battery.
Do not open the battery or short-circuit its contacts.
WARNING-Avoid contact with the rechargeable Lithium-ion battery
if it appears to be leaking. Battery fluid is corrosive, and contact
with it can result in personal injury and/or property damage.
To prevent injury or damage:
If the battery leaks, avoid with the battery fluid.
If battery fluid gets into your eyes, immediately rinses your eyes
with clean water and seek medical attention. Please do not rub
your eyes!
If battery fluid gets onto your skin or clothing, immediately use
clean water to wash off the battery fluid.
3.3.1 External Power supply
We have two methods to provide the external power to the receiver
by the CHC GPS to PC cable+ Power Adapter or CHC GPS to PC cable+
external power cable (option purchase)+ car battery.
In the office, the Power Adapter is connecting with AC
power of 100-240V, the output port of the Power Adapter
connects with the Power Port of the GPS to PC cable,
shown as Figure3.3.1-1.
In the field, the external power cable is connecting with
the Car battery, the output port of the external power
cable connects with the Power Port of the GPS to PC cable,
shown as Figure3.3.1-2.
3.3.2 Internal Battery
Two rechargeable lithium-ion batteries are supplied with the
receiver.
●Recommendations for the battery daily use
Figure3.3.1-1
Figure3.3.1-2
Figure3.3.1-2

Product View
15
The rechargeable Lithium-ion battery is supplied partially charged.
The following recommendations provide optimal performance and
extend the life of your batteries:
Fully charge all new batteries prior to use.
Do not allow the batteries to discharge below 5 V.
Keep all batteries on continuous charge when not in use.
Batteries may be kept on charge indefinitely without
damage t the receiver or batteries.
Do not store batteries in the receiver or external charger
unless power is applied.
If you must store the batteries, fully charge them before
storing and then recharge them at least every three months.
●Charging the Battery
The battery fully charged will take approximately three hours each
using the charger attached.
Connect the Power Adapter and the charger together.
The red LED in the middle indicates the charger is powered
on.
When the battery is placed in the right place, the
Green/Yellow LED will start to flash or turn on.
The Green/Yellow LED indicates the statement of charging.
When it is flashing, it means the battery is on charging, and
the flashing speed tells the progressing of the battery
charging, in other words, when the battery fully charged, the
Green/Yellow LED will keep lighting but no flashing any
more.
●Battery Disposing Notices
Discharge the lithium-ion battery before dispose of it. When
disposing the battery, be sure to do so in an environmentally
sensitive manner. Adhere to any local and national regulation
concerning battery disposal or recycling.
