Do NOT press the BOOST button when the clamps are not
connected to a battery. When the GREEN LED is lit the clamps are
under tension. Do NOT hold the clamps together and cause a short
circuit.
Note: If you cause a short circuit, the GREEN LED will start to flash.
Remove the clamps from the TX-120 EC5 socket and wait about 1
minute before reattaching.
ATTENTION: During the starting process of a car with the
TX-120, neither charge any other devices over the USB
connection, nor charge the TX-120 itself.
To protect the TX-120 and keep its long lifetime, make sure the
power of the TX-120 always is ≥60% when using it to start a car.

Warnings
Do not disassemble the device by yourself (voiding the warranty).
Use the original home charger to recharge the device, or it may
reduce the lifetime of the device.
Make sure the blue plug of the cable into the socket of the device
tightly, otherwise it cannot jump start the vehicle, and even make the
joint melt.
Do not start up car with the car jump starter when the power is
less than 60% (3 BLUE LEDs or less are lighting) to avoid any
damage. Take the product away after the car starts within 30
seconds. Otherwise may cause accidents. When finding the device
expands, do not use it to start the car, to avoid safety accident.
This product cannot be continuous to start the car, it may cause
damage to the product.
Each time you start the interval must be longer than 30 seconds.
When starting the car continuously with 30 seconds pause, and it is
not successful after 3 times, then stop starting to avoid causing
damage to the device or safety accident.

It will cause severe damage to the device when starting the car via
this device continuously or use this device to start the car whose
starting power is over this device, and it may cause safety accident
easily.
Make sure the battery clamps are well connected. If battery
connector is rusted or dirty please clean it first, or the vehicle cannot
be started. Make sure the red clamp is connected to the positive
pole, and the black clamp to the negative pole. Do NOT connect in
the opposite way or it may damage the car.
Once the blue EC5 connector of the clamps is connected to
the EC5 port of the TX-120, NEVER (!) connect the two clamps
together as this will cause a short circuit.
Keep the device away from children. It should be only used
by adults.
