drop during startup, but within 15 seconds of start it should

begin rising.

3. If the charger is working properly, a slow but steady rise of

voltage will still be observed from 30 seconds to 1 minute, and

usually beyond.

Static Diagnostic Check

This test employs the internal battery voltage measurement. It takes a

little more time on the machine because the battery must be

discharged some before measuring voltage, and then recharged

through normal use for several minutes to get an accurate result.

1. Without stepping, press START. Press and hold the + and - keys

of the INTENSITY section (left side of display). LED test will start.

When LED test has most LEDs lit (number 8s, and dot display all

lit) press the Fat Burn 2 Program button to measure display (if

necessary, toggle back to LED test by pressing Fat Burn 1

Program button).

2. If left display does not show "bat" press left + switch until it

does. (This voltage typically reads about 0.2 volts lower than a

meter directly on the battery.)

3. Leave this display active for at least 2 minutes; voltage may drop

slightly during this time. Read and record the final voltage

displayed.

4. Exit diagnostics by again pressing the INTENSITY (left) + and -

switches. The Hiker may then be started normally.

5. Run the Hiker in normally (Level 1, at 50 to 60 RPM is fine) for at

least 5 minutes to charge the battery.

6. Stop pedaling and enter diagnostics as described in a and b

above. Make sure that the battery voltage is measured with

most LEDs lit as described above. This voltage should be at

least 0.1 volts higher than the previously recorded value. If so,

the charger is working properly.
