PCMCIA Card Modem
If transmission problems occur, the fetal monitor automatically attempts to resend the remaining trace (up to three times). If these retries fail, and data transmission stops, you will see the error message ERR77 and hear a triple beep tone (beep, beep, beep!). The fetal monitor will make no more attempts to resend data. Acknowledge the error message by
scanning the barcode Display Memory or by pressing a key, such as 
. You can try to send the remaining trace at a later time. If this problem persists, refer to “Troubleshooting and Error Messages” on page 165.
If the barcode Transmit Data is scanned and the transmission of the stored trace is unsuccessful:
1.The error message Err 77 is displayed and a triple tone (beep, beep, beep!) is produced. Acknowledge the error message by scanning the barcode Display Memory or
by pressing a key, such as 
.
2.The error message Err 77 clears and two (three in the case of the Series 50 A Dual Ultrasound model) decimal dots are permanently displayed, indicating that fetal trace data is still stored in the memory.
When fetal trace data is sent to the receiver, it is sent in
If the barcode Transmit Data is scanned and no fetal trace is stored in memory, 0 is briefly displayed. Since there is no data stored, no transmission takes place.
