Relay-Key Online Guide

What to do when this happens?

The confirmation LED is lighted red

If you press the communication button and the confirmation LED lights red except when implementing the initial registration of the Relay-Key, that means that there is an error in the Relay-Key internal processing.
If this happens, the error can be resolved by connecting the Relay-Key to the PC.

There is no reaction when inserted in the USB port

Is the Relay-Key firmly and completely inserted into the PC's USB port?
Is the connection loose?
If so, use the accessory USB extension cable.

[If the problem is not resolved]
Is the special application activated?
* Shortcut execution

* Confirmation that the application is resident in memory


If it is activated and there is no particular response, confirm the conditions of Relay-Key registration in the PC.

Confirming the conditions of registration in the PC

[» Display Procedure for confirming the conditions of registration in the PC]

Execute the following tasks as indicated in the procedural manual:
(1) Confirmation of registration conditions
(2) Correction
(3) Final confirmation

Please send an inquiry if it is not possible to avoid problems that differ from this example after referring to the online guide.

The confirmation LED does not extinguish after disconnection from the USB port

If this happens, try reinserting the batteries. After that, the confirmation LED should light red when the communication button is pressed.
After confirming this, insert the Relay-Key into the PC and resolve the error.

When replacing or reinserting the batteries

The batteries must be replaced or reinserted at times due to low level charge, drops, etc.
At such times, the internal Relay-Key clock is reset and the confirmation LED will therefore light red even if the communication button is pressed.
Insert the Relay-Key to the PC and resolve the error.
