Thank you for purchasing Sphere TPMS! Sphere TPMS is an innovative safety
accessory which provides drivers with information for tire pressure and tire
temperature. The product warns the user of leakage, high/low tire pressure, low
sensor battery, high tire temperature while driving. Sphere TPMS also helps drivers
maintain sufcient levels of tire pressure for safer driving and reduced tire wear.
1. This product must be correctly installed before use. Avoid damaging the
sensor and the wheel when installing. Internal sensors should be installed
according to manual instructions by a professional auto-technician.
2. Installation or use of this product cannot substitute the user's regular
maintenance and self-check of auto parts.
3. Do not handle this product while driving. Failure to concentrate on driving may
result in serious consequences.
4. This product is a safety accessory and cannot prevent puncture or tire
leakage. Please react promptly to the product warning signals and resolve
abnormal tire conditions before getting back on the road.
5. The user is responsible for safe driving, taking care of their vehicle, and
ensuring the correct installation and use of the product. Sinotek assumes
no liability for damages and losses.
6. Whenever the position of a tire is changed (tire rotation), the sensor must be set
to the correct position on the display (see Tire Swap function on page 9).
7. All sensors are already paired to the display in the factory. Users DO NOT
need to pair the sensors to use this product for the rst time.

Q & A After installation, why does air leakage occur?
Tire valves may not be of universal standard. Check with your installer.
There are two methods:
1. External sensors can be taken off and screwed onto the correct position;
or
2. Users can utilize the Tire Swap function to exchange two tire
positions each time, until all tires are swapped to the correct position.
Do I need to perform a dynamic wheel balancing?
After installing internal sensors, dynamic wheel balancing is a must.
Dynamic balancing is not required for external sensors.
During a wheel rotation, how can I make sure the sensors are in the right position?

Q
A
What happens if I separate my trailer and my 4-wheel vehicle? Will the
display alarm and report sensor failure?
If the display fails to receive all of the pre-paired tyre signals from the
trailer at the same time, it will pause the status of trailer data. The display
will not alarm and report for sensor failure.
Q
A
Where do I nd help?
The rst point of contact should be your direct seller. For more help, visit
our website www.coastrv.com.au.
Q
A
What to do if I want to upgrade to ten tires?
Please purchase extra sensors from authorised stores and follow the
sensor pairing instructions in this manual to pair the extra sensors to your
display. It is easy.
Q
A
What happens if I lost a sensor?
Please purchase a new sensor from a distributor.
Q
A
1. Ensure that all the sensors are present, and the display is fully
charged and turned on;
2. Ensure there are no electronic interference around;
3. Drive the vehicle over 20km/h for 5 minutes;
4. Ensure that the sensor battery is working and then repeat step 3.
[Note: The display has low sensor battery warning to alert the user. If it
is a new unit, skip to step 4.]
5. If data is still missing, commence sensor pairing.
