Supplement Troubleshooting

No sound is heard.

Check the following items.

[Assembly]
Ensure that the battery-box connectors are fully engaged with the corresponding circuit-board connectors.
Ensure that the head plug is securely inserted into the unit’s jack.

[Batteries]
Replace any batteries that have run out of power, taking care to ensure that you insert them in the correct direction.
When the recorder is not being used, turn it off and remove the batteries.

[Speaker and microphone]
Ensure that the speaker and microphone cords have not become detached.
To fix a detached cord, remove all adhesive from the surface using a craft knife or the like, and then resolder.

[Circuit board]
If excess pressure is applied to circuit-board components from above, solder on the rear side may become detached.
If this has occurred, repair the damaged solder.

Recordings are not being made properly.

First, check the switch. Ensure that it is set to Record (R).
If it is, then make sure that you are using the erasing magnet correctly. Specifically, the erasing magnet should be slid along the recording surface in one direction only. If you slide in more than one direction, recording will not have the desired effect.
If you are trying to record onto a material other than the wire provided, make sure that it is suitable for recording. While the recorder generally works with thin or flat steel objects, not all such items are suitable.

The recorder does not play properly.

First, check the switch. Ensure that it is set to Play (P).
Certain words are difficult to record than others. If a particular word or sentence does not work, try another.
The direction in which you slide the head is also important. In specific terms, the erasing magnet and the head must always be slid in the same direction.
When performing this, be sure to slide the head carefully along a guide. Aim to use the same section of metal when recording and playing. Even if you are only slightly out of position, your recording may become difficult to hear.
The speed at which you slide the head may also make it difficult to play your recording.
The closer the speed of sliding during play is to that during recording, the better your recording will sound. However, very slow speeds significantly reduce the play volume.
As a general guideline, you should aim to slide from the left to the right of the rail in approximately one second.
