Auto Clip Tuner

Item ref: 173.259

User Manual

Errors and omissions excepted.

Operation

Open the clip and clamp onto a headstock or other contact

surface. Pressure pads in the clip will switch on the power.

Play a note and the contact pickup will detect the pitch - the
display states the nearest note and a virtual needle shows

the tuning status. If the note is not correct, tune the
instrument closer to pitch until the correct note is shown.

If the needle is to the left, the note is flat

and the display will be lit in a red colour.
If the needle is in the centre, the note is in tune

and the display will be lit in a green colour.
If the needle is to the right, the note is sharp

and the display will be lit in an orange colour.

Removing the clip from the instrument will switch off the

power. 5 minutes without any note detected will also switch
off the power.
