Users Manual

Bike pod Model: AD202 The AD202 bike pod is equipped with the latest 2.4GHz ANT+ Sports System to achieve reliable transmission linkage with other devices. PACKAGE ITEMS The package should include the following items: • 1 x AD202 bike pod and cushion • 1 x magnet (plastic base) • 1 x magnet (with screw) • 6 x nylon cable ties • 1 x CR2032 3V lithium batteries (already installed in bike pod) SELECT MEASURMENT MODE This bike pod measures speed and cadence. First decide what you wish to measure as the positioning of the bike pod depends on the chosen measurement mode. To select measurement mode (speed / cadence): 1. Use a coin to open the battery compartment lid by turning it anticlockwise. 2. Remove the battery. 3. Slide switch to select SPEED or CADENCE (refer to markings on the unit). 4. Put battery back into place. 5. Secure the lid by turning clockwise. 6. Insert sensor into the provided cushion to help achieve a better grip on the bicycle. INSTALLING THE BIKE POD SPEED 1. Position sensor onto one side of the bicycle fork, with logo visible. 2. Thread a nylon cable tie through each of the holes on the sensor. Loop cable tie around the bicycle fork, then thread the end through the opening and past the ratchet. Pull to secure into place. TIP Cut away unnecessary cable tie to avoid it being caught in the wheel while in motion. 3. Unscrew magnet and press slot onto spoke, with flat magnet surface facing sensor. 4. Using the alignment notch as a guide, position magnet so that it will pass the sensor at the correct position. Screw into place. NOTE Improper alignment may affects sensor’s performance. CADENCE 1. Choose the crank arm which is not on the same side as the chain ring. Place magnet (with plastic base) onto the crank arm of the pedal, making sure the magnet faces the chain ring. 2. Thread a nylon cable tie through each of the holes on the sensor. Loop cable tie around the crank arm then thread the end through the opening and past the ratchet. Pull to secure into place. 3. Using the alignment notch as a guide, position sensor on any bar which is along the magnet’s path. 4. With the battery compartment facing the magnet, thread a nylon cable tie through each hole on the sensor. Loop cable tie around the bar then thread the end through the opening and past the ratchet. Pull to secure into place. NOTE Improper alignment may affects sensor’s performance. TIP Cut away unnecessary cable tie to avoid it being caught in the wheel while in motion. PAIRING DEVICE The AD202 can be paired with your heart rate monitor (watch) or sports accessory to provide speed / cadence readings. The bike pod has a maximum transmission range of about 62.5 centimeters (25 inches). To pair with Oregon Scientific heart rate monitors that use the 2.4GHz ANT+ Sports System, please refer to below pairing instructions. To pair with sports accessories or heart rate monitors of another make, please refer to manufacturer’s instructions. PAIR WITH OREGON SCIENTIFIC SPORTS ACCESSORIES / HEART RATE MONITORS NOTE While pairing, make sure to stay away from other devices and move the device to pair close to the watch. 1. Press MODE repeatedly to select . The watch will show how many and which devices are paired (if any). If no device is paired, the watch will show “0 DEVICE PAIRED”. 2. Press SET to enter “PAIR DEVICE?”. Press SET to start pairing. When the bike pod is paired successfully, the watch will display NOTE If pairing is weak and unstable: • Shorten the distance between the device and watch. • Re-adjust the position of the device. • Check the batteries. Replace them when necessary. If the watch is already paired with a bike pod, you have to first delete the bike pod before you are able to pair with another bike pod. INPUT BIKE WHEEL SIZE NOTE The watch will not show “WHEEL SIZE” if no bike pod is paired. If your watch is paired with bike pod, the watch will prompt you to input the wheel size values. Go directly to step 5. For normal setting procedure, start with step 1. 1. Press MODE repeatedly to select . 2. Press SET. 3. Press ST/LAP/+ repeatedly to select “WHEEL SIZE”. 4. Press SET. 5. Input the bike wheel size by pressing ST/LAP/+ to increase values or -/SP to decrease values. 6. Press SET to confirm. BIKE WHEEL SIZE Match the ETRTO or wheel size diameter printed on the wheel with the wheel size setting at the right hand column of the table below. Input the relevant wheel size setting number after bike pod is paired. ETRTO Wheel size diameter (inches) Wheel size setting (mm) 25-559 26 x 1.0 1884 23-571 650 x 23C 1909 35-559 26 x 1.50 1947 37-622 700 x 35C 1958 47-559 26 x 1.95 2022 20-622 700 x 20C 2051 52-559 26 x 2.0 2054 23-622 700 x 23C 2070 25-622 700 x 25C 2080 28-622 700 x 28 2101 32-622 700 x 32C 2126 42-622 700 x 40C 2189 47-622 700 x 47C 2220 NOTE Wheel sizes on this table are for reference only as wheel size depends on the wheel type and air pressure. REMOVE PAIRED DEVICE NOTE The watch will not show “DEVICE REMOVE” if no device is paired. 1. Press MODE repeatedly to select . 2. Press SET. 3. Press ST/LAP/+ repeatedly to select “DEVICE REMOVE?”. 4. Press SET. 5. Press ST/LAP/+ to select which device to delete. 6. Press SET to confirm selection. REPLACE BATTERY If the watch indicates sensor battery is low, replace batteries promptly as it may affect the accuracy of the readings. To replace the sensor battery: 1. Use a coin to open the battery compartment lid by turning it anticlockwise. 2. Remove the old battery and insert a new CR2032, 3V lithium battery. 3. Secure the lid by turning the coin clockwise. IMPORTANT Remember to pair device after every battery replacement or reset. CARE INSTRUCTIONS • Do not wrap the sensor in a wet towel nor with other wet materials. • Do not place or wash the sensor under running water, instead clean it with a wet cloth. • Do not store the sensor in a hot (about 50°C) and humid (about 90%) environment. WATER RESISTANCE The AD202 is water-resistant up to 10 meters (32.8 fe…

Operational Description

AD202 Technical Description The Bike Speed Sensor is a one way wireless transmitter that operates in conjunction with the Bike Console. The reed switch on the exercise bike detects the rotation of the wheel on the bike. The microcontroller in the bike speed sensor read the signal from the reed switch and activate the nRF24L01+ 2.4GHz transmitter IC to send encoded 2.457 GHz RF signal containing the number of revolution and timing information to the Console and the console will calculate and display speed, distance and energy consumption information on its LCD and may store these information.. The RF output of the nRF24L01+ 2.4GHz transmitter IC is connected to the antenna via an Antenna matching network. This network is used to match the impedance of the antenna to the nRF24L01+ 2.4GHz transmitter IC and suppress unwanted spurious transmission. The data signal is transferred through matching network (L1, L2, L3, L4, L5, C3 and C22) fed to the antenna. All rights reserved.
