< Notes for Communication Error >
If a communication error occurs, one of "-- IRC BUSY --, ECR#-xxx ERROR or ECR#-xxx BUSY"
(xxx = ECR machine number) is displayed, then;
- retry the communication by pressing CASH/TTL 25 key, or
- cancel the communication by pressing CL key, then check the slave ECRs causing the communication error.
When CL key is pressed, depending on the cases, the master displays REQ.Z70-xxx or REQ.X70-xxx with
sequential clerk number (not clerk code) and prints the message on the journal.
When REQ.Z70-xxx is displayed,
(This is displayed when the master collects the clerk's data from the slave, but the slave has not deleted it yet.)
1. Press CL key again to clear the error condition.
2. Then perform the clerk code entry again to continue the operation.
3. After the operation is completed, take Z-70 individual clerk balance report on the ECR machine
number xxx to delete the clerk's data on that ECR so that the master and slave may not have the same
clerk's data.
When REQ.X70-xxx is displayed,
(This is displayed when the master collects the clerk's data from the slave and the slave deletes it but the
confirmation of such deletion has not been sent to the master yet.)
1. Press CL key again to clear the error condition.
2. Then perform the clerk code entry again to continue the operation.
3. After the operation is completed, take X-70 individual clerk balance report on the ECR machine
number xxx to ensure that the clerk's data has been deleted from the slave.
