Saber Hand Wind Audio Player - Maintenance Guide
3. Troubleshooting Procedure
The key to identifying and repairing electronic devices is to have a logical approach to
troubleshooting and fault diagnosis. The first step is to examine carefully all the symptoms of the
fault, and to identify the problem areas. This guide is designed to assist you in identifying the fault,
and the steps needed to repair the player.
The three major areas of troubleshooting the Saber player are:
•
Power. Generator, external DC, and Battery issues.
•
Audio file preparation. How to download, and setup
playback of audio files.
•
The use of the Player to play audio files.
3.1 Power Management
All electronic devices require power to operate. The
Saber is designed specifically to be able to use the
built in hand-wind generator as well as external
power to charge the internal battery to allow the
player to function.
We can divide the power into 4 categories:
Hand-Wind Generator, External DC power, Internal
battery, power management circuit.
3.1.1 Hand-Wind Generator
The onboard generating unit contains the only moving part in the player. It consists of:
•
Crank handle
•
gears and pulley wheel
•
belt
•
idler arm
•
generator
•
Red light
If the red light does not light when turning the crank handle in a clockwise direction, further
investigation steps need to be taken. This will require the opening of the player and possible
replacement of parts. Please follow the assembly instructions on page 15 in this manual, and check
that the belt, gears and generator are working correctly, and replace any parts that are preventing the
reliable running of the hand-wind generator subsystem.
