6. Care and Troubleshooting

Your Teledex SIP LD series IP phone will provide years of trouble-free service, particularly if it is maintained in an indoor environment.

6.1 Cleaning the SIP LD Series

Dust or deposited materials caused by normal handling of the phone handset or base should be removed occasionally to ensure optimal performance. Use a soft cloth moistened with water to wipe the plastic exterior parts.

CAUTION: Do not use solvents, powders or spray cleansers that may leak into the electronic components and cause damage.

6.2 In Case of Trouble

If the SIP LD series does not seem to function as expected, there are several troubleshooting techniques that may be tried before calling the network administrator.

6.2.1 Disconnect From the Network

Unplug the network cable from the wall jack. Wait at least fifteen (15) seconds, then plug the cable back into the same jack. The phone will attempt to re-establish contact with the IP-PBX. In many cases, this will restore normal operation.

WARNING: Risk of electrical shock! Dangerous voltages may be present on the exposed terminals of the network patch cable after it is plugged into the network wall jack.

6.2.2 Disconnect the PC

If there is a PC or other network device connected to the port on the side of the phone, disconnect the cable to the PC or device from the base, then perform the actions from section 6.2.1 (Disconnect From the Network).

6.2.3 Check the Cords and Cables

If the previous two steps do not solve the problem, all of the cords and cables (including handset cord and headsets) should be disconnected, inspected for dirt or corrosion, and reconnected.
