To be able to use the Auto-Start function, the dust extractor must be connected via Bluetooth® to an Auto-Start Remote GCT … (39).
For this, the dust extractor and the Auto-Start Remote must be located in the immediate vicinity of one another.
If the on/off switch (14) of the dust extractor is turned to the
position, the dust extractor automatically begins searching for an Auto-Start Remote GCT …. The statusbar (2) and the Auto-Start function indicator (4) slowly flash blue.
Reconnection to a known Auto-Start Remote:
If the dust extractor has already been connected to an Auto-Start Remote GCT … and this Auto-Start Remote is functional and within range, the connection to this Auto-Start Remote is automatically re-established.
Establishment of a new connection (first-time connection or connection to another Auto-Start Remote):
- Press and hold the pairing button (5) on the dust extractor until the statusbar (2) begins rapidly flashing blue.
- Then promptly press and hold the start/stop button (41) on the Auto-Start Remote (39) until the status indicator (40) on the Auto-Start Remote flashes blue twice.
Connection successfully established:
- The statusbar (2) and the Auto-Start function indicator (4) on the dust extractor light up green.
