Please check the receiver settings to make sure the Power feature is turned off. Please make sure that the speed sensor and the monitor are mounted on the same side of the bike. If you have the speed sensor on the right side of the fork, make sure the monitor is mounted on the right side of the stem or vice versa. Also the speed sensor should be mounted as high up on the fork as possible, the sensor should be right below the brake. When the spoke magnet passes the speed sensor is should be within 2 mm of the sensor and it should pass through the middle of the sensor. The red led light will flash to let you know that the sensor is picking up the magnet. This light will only flash for about 30 times then it will default off. If possible you should use the screw on magnet, not the clip on magnet, the clip on magnet has a tendency to shift out of position on the spoke. Also make sure that the zip ties are tight enough to keep the speed sensor from shifting if you ride over rough roads, the zip ties should be tightened as much as possible. The angle between the sensor and the receiver has an effect on the transmission range and it should be as close to 90 degrees as possible. In many bikes the wheel is so close to the fork that the optimal angle cannot be achieved, however, an adequate range can be achieved by adjusting the range setting in the sensor and the angle between the sensor and the receiver. There are three possible settings for the transmission range in the sensor: short, medium and long. We strongly recommend that you send the sensor to an authorised Polar Service Center, where the unit is tested for water resistance after adjustment. Water resistance cannot be guaranteed after an unauthorised service. If you wish to adjust the sensor by yourself, follow the attached instructions carefully and note that the warranty does not cover damage or consequential damage caused by service not carried out by an authorised service center of Polar Electro. (See attached file: TRANSMISSION RANGE ADJUSTMENT.doc) If you would like to return your unit for service please return your sensor plus $2.95 for return shipping and handling to: Polar Electro Inc. 1111 Marcus Avenue Suite M15 Lake Success, NY 11042-1034 Attn: Technical Service Please include your name, address and daytime phone number in the event we need to contact you. It is recommended you return your unit in a traceable manner such as UPS Ground or Insured US Mail. If you need further assistance please feel free to contact customer service at 800-227-1314 or 516-364-0400. Thank you for choosing Polar. Customer Service POLAR ELECTRO INC.

TRANSMISSION RANGE ADJUSTMENT Please note! We highly recommend that you send the Cadence Sensor to an authorised Polar Service Centre for the transmission adjustment, where the unit will be water-resistant tested after the adjustment. Water resistance cannot be guaranteed after an unauthorised service. With the S-series bike sensors you are able to adjust the transmission range of the sensor. However, you should be aware that you might cause interference to other cyclists training with Polar Speed/Cadence Sensors if you do adjust the transmission range. This function enables you to measure speed if you are cycling with an indoor trainer (i.e. stationary bicycle without a front wheel). When you adjust the transmission range to the longest option you can install the speed sensor on the seat stay and the spoke magnet on the rear wheel. The transmission range options are • min 60cm (parallel) • min 90cm (parallel) • min 110 cm (parallel) The transmission range options are default measurements. Note that the range may be shorter when the sensor is installed on a bicycle because the bicycle frame may affect the magnetic field, which shortens the transmission range. Note also that a longer transmission range shortens the battery life. 1.
Put the unit on a clean, dust-free pad on a flat table surface and open the sensor by removing the two screws counter-clockwise, with a small screwdriver.
2.
Lift the case off carefully. Hold the sensor cover upwards ensuring that the PCBA (printed circuit board assembly) stays in the case.
3.
Remove the PCBA carefully.
4.
Adjust the jumper. See the position of the jumper in relation to the transmission range in the following pictures.

Make sure that the jumper is securely attached to the pin(s).
6.
Put the PCBA back into place.
7.
Make sure that the sealing ring is not damaged and is in its groove. Replace the sealing ring, if necessary. Silicon paste can be used to keep the ring in place. Replace the case.
8.
Put the two screws in their holes and tighten them first to 0.5 kgf.cm, holding the case level while tightening the screws. Do not force the screws or damage the existing threads. After tightening both screws to 0.5 kgf.cm tighten them to 2.0 kgf.cm.
9.
Test the sensor by checking that it gives out an orange flash when the magnet passes the sensor.
