5.5 Using Voice Mail
5.5.1 Message Waiting
If the red message waiting indicator is flashing slowly, voice
mail messages are waiting to be retrieved.

Press the MESSAGE key. The speakerphone will be activated
(unless the handset is off-hook) and the phone calls the
voice mail server. Follow the voice prompts for entering
your password, listening to, saving and deleting messages.

before using this feature. (Refer to subsection 3.2.3)
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.
