Keep clear of the motor and moving pas while in use. The enclosure will heat up when subject to prolonged, extreme use. Always keep the cooling holes clear and plug it in for extreme use to keep the fan working. Please use the T2 on a stable suace with adjusted leveling feet before use. Use caution when standing while riding on T2. Do not install or disassemble the bicycle until T2 completely stops. Do not use other power source to power T2. Please conrm whether the bicycle is installed properly before eve ride.

For , refer to "2.4 For Bikes with Rear Thru-Axles" for installation.thru-axle For , refer to "2.5 For Bikes with Quick Release Skewers" for quick release installation. Carefully go through the manual and compare it with the actual pas to make sure all of them are complete and properly installed before mounting your bike to T2. 1 T2 is compatible with most quick release and thru axle frames including those with disc brake sets. However, there are still a few special frames, because of the shape of the rear fork and the location of the disc brake set, may not be compatible with T2. For bikes with disc brake sets and a chain stay shaped as shown below, they are ve likely to be incompatible with T2, and do not force to install. For bikes with disc brake sets, make sure the disc brake set is not against the housing of T2. If you nd any contact or friction, do not force to install. 3 Special-shaped chain stay Possible area in contact Read the manual throroughly and be sure to follow the instructions provided in the manuals when using T2. Don't hesitate to contact us for suppo and don't force to install. CYCPLUS is not responsible for damage or loss caused by incorrect installation, incompatible bike frame or customer's forcing installation. 4 For hydraulic disc brakes, install the pad spacer between the brake pads(as shown on the right) after removing the rear wheel, to prevent you from accidentally closing the brake without the rotor in place. Please use your own pad spacer if the spacer coming with T2 is not compatible with your disc brake. 2 Use this notch to clip the spacer to the retaining pin Install the Thru-axle adapter-L(04) 2 1 4 8 1 4 2 Install the Thru-axle adapter-R(03) with 17mm wrench(07) 1 2.5 For Bikes with Rear Thru-Axles 06 Outwards for Mountain bike Outwards for Road bike T2 comes preinstalled with thru-axle adapter. 3 Secure the bike with the thru-axle of your bike. 5 4 6 Original thru-axle 07 Inse the quick release skewer into the axle of T2 and install the nut in place, but don't tighten it yet, in order to install the bike frame.

The PCB requires the welding to function properly. This test uses an externalbatteryfortesting.  TestingResult All the reflection measurements were performed with a network analyzer connected to a semi-rigid coax cable, which was soldered to the feed point of the antenna. Because of the small size antenna and the small ground plane this kind of measurements is heavily affected by the presence and placement of the coax cable. This influence can result in a small uncertainty in resonance frequency and measured reflection. Typically different placement of the semi-rigid coax cable could change the resonance frequency with 5 -10 MHz and the reflection with 3 - 4 dB.
