Set the Clock
Your computer is equipped with a digital clock that displays time of day in a 12 hour or 24 hour format.
STEP 1
Press the RIGHT button to advance to the CLOCK display screen (TIME). In the Clock display screen (TIME), press and hold the RIGHT button for three seconds.
STEP 2
“12” or “24” will flash in the lower line of the display. Press the LEFT button to select 12 hour or 24 hour mode. Press the RIGHT button to confirm
your selection and advance to the hours setting.
STEP 3
The hours will flash. Press the LEFT button (or press and hold) to advance the hours. Press the RIGHT button to advance to the minutes setting.
STEP 4
The minutes will flash. Press the LEFT button (or press and hold) to advance the minutes. Press the RIGHT button to set the time and return to the
Clock display screen.
Installation
We recommend that you install the Tempo cadence computer in the following manner, starting with the sensor units on the chainstay and
working up to the mounting bracket on the handlebar.
WHEEL MAGNET AND SENSOR INSTALLATION
STEP 1
Identify the two sensors and magnets. The cadence sensor is connected to the shorter cable and has “CADENCE” printed on one side. The
cadence magnet is the square, flat magnet with “CADENCE MAGNET” molded on one side.
STEP 2
Using two zip-ties, mount the cadence sensor loosely (so that you can slide it around) to the outside of the left (non-drive side) chainstay. See Figure 3.
STEP 3
Use an included zip-tie to attach the cadence magnet loosely to the inside of the left crank arm directly opposite the cadence sensor.
The words on the magnet should face the sensor. Adjust the position of the magnet and sensor until the magnet passes the sensor with
1mm-3mm of clearance.
STEP 4
Using two more zip-ties, mount the speed sensor loosely (so that you can slide it around) to the inside of the left (non-drive side) chainstay. See Figure 3.
STEP 5
Attach the wheel magnet loosely to one of the spokes on the same side of the wheel as the sensor. Adjust the position of the magnet and sensor
to achieve 1-3mm of clearance between the two (1mm is about the thickness of a penny). See Figure 3. If the magnet and sensor are not close
enough, the computer will not pick up a reading or readings will be inconsistent and erratic. Most problems that occur when installing a new
computer are related to magnet and sensor alignment and spacing.
STEP 6
Once the speed and cadence sensors and magnets are aligned properly, tighten the zip-ties to secure all four in place and trim the excess zip-tie
ends with scissors.
Determine Wheel Size
The Tempo computer uses wheel circumference (measured in millimeters) to calculate
speed and distance. Before you can program the computer you must calculate wheel
circumference using one of the three methods below.
1. Select size from chart (least accurate): Use the chart to find the circumference for your
tire size. The chart lists the programming sizes for some of the most popular tire sizes
currently in use. These numbers are estimations which may not precisely match the
circumference of your wheel, due to variations in tire size between brands and models.
2. Measure wheel diameter (more accurate): Measure your wheel diameter (including
wheel and tire) in millimeters (1 inch = 25.4mm) and multiply by 3.1416. This value is
your wheel circumference.
3. Perform roll-out test (most accurate): See Figure 2.
STEP 1
Stand your bicycle upright. With your tire inflated to its proper pressure, rotate your
front wheel so that the valve is located at the bottom (6 o’clock position). Make a mark
on the floor to indicate the valve location.
STEP 2
Roll the bicycle forward in a straight line for one complete wheel revolution, until the
valve is again at the bottom (ideally, you should be on the bike). Make a mark on the
floor to indicate the valve location.
STEP 3
Measure the distance between the marks in millimeters (1 inch = 25.4mm). This value is your wheel circumference.
Program the Computer
Before using your Tempo computer, you must program wheel size (see “Determine Wheel Size,” above), select a speed scale (miles or kilometers),
set the odometer (if desired), input your weight and set the clock. The first step is to select the speed scale.
Select Miles or Kilometers, Program Wheel Size & Set the Odometer
The Tempo computer is capable of displaying speed and distance information in either miles or kilometers. Also, the odometer can be set so that
cumulative mileage can be restored after a battery change or transferred from another computer.
(SELECT MILES OR KILOMETERS)
STEP 1
Press the RIGHT button to advance to the Odometer display screen (ODO). In the Odometer display screen (ODO), press and hold the RIGHT
button for three seconds.
STEP 2
“km/h” or “m/h” will appear on the right side of the screen. Press the LEFT button to select miles (m/h) or kilometers (km/h).
STEP 3
Press the RIGHT button to confirm your selection and advance to the wheel size setting screen.
(PROGRAM WHEEL SIZE)
STEP 4
After the speed scale has been selected, the computer will automatically advance to the first wheel size programming screen (
➊
). The digit at
the right of the screen will flash. Press the LEFT button to adjust the flashing digit according to the wheel circumference value determined above.
Press the RIGHT button to advance to the next flashing digit.
STEP 5
Repeat this sequence until the correct wheel size has been entered. Then press the RIGHT button to advance to the second wheel size setting screen (
➋
).
STEP 6
The digit at the right of the screen will flash. Press the LEFT button to adjust the flashing digit. Press the RIGHT button to advance to the next flashing digit.
STEP 7
Repeat this sequence until the second wheel size has been entered. Then press the RIGHT button to advance to the odometer setting screen.
(SET THE ODOMETER)
STEP 8
After programming wheel size, the computer will automatically advance to the odometer setting screen. (If you don’t want to change the
