Use UPC Finish Connectors Only -- DO NOT insert APC connectors into the optical ports.
Caution
The OTDR is equipped with a protection circuit to avoid damage from live fiber connections, the in-

If a live fiber is connected to the OTDR and a scan is attempted, a warning dialog will be displayed as in
fig. 2.1. Immediately remove the live fiber from the OTDR and press select to clear the message.
