The KORG GM-1 features the following controls and parts:

1. SYNC button: Press to synchronize devices. Hold down to Mute.

2. MODE button: Press to cycle through settings. Hold down to turn Power on/off.

3. Display: Shows the current settings.

4. Jog Switch: Slide to change values for the selected setting.

5. Ear cap: Attach the included ear cap to the GM-1.

6. Ear clip: Attaches the GM-1 to your left or right ear.

1. Open the ear clip, and move the round part on the tip to match the ear onto which you’ll attach the GM-1.

2. Place the GM-1 on the hollow part of your ear around the ear hole, and close the ear clip to attach it.

Note: The round part can rotate a maximum of 220 degrees. It will break if you attempt to rotate it farther than this.

As this is a small and lightweight device, there is a risk that small children may place it in their mouth and ingest it. Keep the device out of reach and store it away from small children.

1. Slide the lid open.

2. Pull the lid diagonally upwards, and then insert the battery.

Please note the following:

• Make sure that the GM-1 is turned off before replacing the battery.

• Make sure to observe the correct polarity.

• The battery (CR 2032) is not included, so please obtain it separately.

To turn on the power: Hold down the MODE button until the display lights.

To turn off the power: Hold down the MODE button until the display goes dark.

The display will blink if the battery has worn down. When this happens, replace the battery as soon as possible.

Press the MODE button to switch between the setting screens for Tempo, Beat, Rhythm, Volume, and Pitch, in that order.

1. Press the MODE button to display the Tempo setting screen.

2. Use the jog switch to set the tempo from 30 to 252 min (BPM). Slide and hold the jog switch to make the tempo continue to change.

1. Press the MODE button to display the Beat or Rhythm setting screens.

2. Use the jog switch to set the beat and rhythm.

• Beat: Select a beat from 0 beat to 9 beat.

• Rhythm: Select a rhythm pattern from Quarter Notes, Duplets, Triplets, or Quadruplets.

These settings will be stored in the device. However, the settings will not be stored if the device is not turned off in the ordinary manner (such as when the battery runs out).

1. Press the MODE button to display the Volume setting screen.

2. Use the jog switch to select the volume from “Volume: Low” to “Volume: High”.

This device’s volume has been set to be a little loud, since it may be used when practicing musical instruments. If the device seems too loud, fasten it to your ear at a position slightly away from the ear hole. To protect your hearing, avoid using this device for long periods of time.

1. Press the MODE button to display the Pitch setting screen.

2. Use the jog switch to set the pitch from “Pitch Low” to “Pitch High”.

The count timing for two or more GM-1 devices can be synchronized. The GM-1 device that drives the base tempo is called the “source”, and the other GM-1 devices that will follow that tempo in sync are called “replicas”.

Note: The GM-1 cannot be synchronized with SyncMetronome.

1. Match the protruding part of the GM-1 that will be the source to the recessed part of the GM-1 that will be the replica, as shown in the diagram.

2. Press the SYNC button on the GM-1 that will be the source.

When the synchronization is complete, you’ll see the volume shown on the replica’s display. The tempo, beat and rhythm of the replicas will be overwritten by that of the source.

The metronome sounds can be muted.

1. Hold down the SYNC button. Press the SYNC button again to cancel muting.
