Advanced Wireless Communication Features
Ensuring Reliable Operation and Safety

Tool Distance
A highly reliable data signal can be transmitted if the tool is within 10m of the assembly qualifier and if there are no barriers between the tool and qualifier.

ID management is not required
The qualifiers accept only registered ID. There is no interference even when multiple tools are used on the production line.

Out of Range Disable Function
In the event that wireless communication cannot be completed between the tool and the qualifier, the tool will be disabled and cannot be operated. Operation of this function is set on the tool body with remote control.

*Communication range varies with operating environment. The presence of metal walls, people, or other objects may result in decreased range.
Important Communication Considerations
There is a risk of less communication range and/or communication error in conditions as below
- Obstacle to disturb radio wave such as metals and/or reinforced concrete between tool and qualifier
- Metal cover on qualifier's antenna
- Operator’s body between tool and qualifier
- Devices creating radio noise such as PC and/or mobile phone near tool and/or qualifier
*If strength of radio signal is weak and/or qualifier’s reaction speed is slow, change qualifier’s location and/or channel setting.
