Do not twist this area.
1. Before installing the device, please confirm if the installation
space can accommodate the product.
2. Be sure to use an adjustable wrench when installing the
pressure gauge. The wrench must complete the equipment
tightening operation at the hexagonal position of the threaded
interface to ensure airtightness. Do not directly fix the device
by twisting other parts!
3. Please make sure to fully charge the product in advance and
use the standard adapter and charging cable when charging.

accordance with the instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
Note: The Grantee is not responsible for any changes or modifications not
expressly
approved by the party responsible for compliance. such modifications could
void the user's authority to operate the equipment.
