Step 1 – Unplug the power and wait for 3 seconds before reconnecting the power. Step 2 – After the power is turned on, start checking if all the cable connections are in place. Make
sure your TA WAN port is connected to your XDSL/Cable.
Step 3 – Try to ping your G/W’s IP address described in section 3.2. You will be able to determine
whether the problem is from the network problem or terminal adapter.
Step 4 – If it is network problem, please contact your ISP or your network administrator and have
them resolve this.
st
section after you purchase the terminal adaptor. If

them, please have your module and series number ready, so the issue can be resolved faster.
Maintenance
We strongly recommend users to operate the terminal adaptor under a safe environment. These are
few tips that you can do to maintain your G/W:
Do not block the airflow entrance of the G/W to avoid the potential over heating problem.
Do not put heavy objects on top of the G/W.
Periodically clean up the dust near the G/W operation area. Do not use a wet material to
clean up the G/W.
If you are not using the connectors (2 RJ11 and 2 RJ 45). Please seal them up to avoid
getting dust into the G/W.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two condition s: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
