1Warnings & Safety Information
1. Both appliance power cables must be removed from the device for Power Disconnection.
2. Remove the phone cable from the POTS interface before servicing.
THUNDERSTORM AND LIGHTNING WARNING:
DO NOT USE Tieline codecs during thunderstorms and lightning. You may suffer an injury
using a phone, Tieline codec, or any device connected to a phone during a thunderstorm.
This can lead to personal injury and in extreme cases may be fatal. Protective devices can
be fitted to the line, however, due to the extremely high voltages and energy levels involved
in lightning strikes, these devices may not offer protection to the users, or the Tieline codec
and equipment connected to the codec.
Secondary strikes can occur. These secondary strikes are induced by lightning strikes and
also produce dangerously high currents and energy levels. You only need to be near an
object struck by lightning to lead to personal injury or damage to equipment. e.g. if you are
located near a lighting tower at a sports facility, water features and drains on golf courses,
you may be affected by these secondary strikes.
Damage to personnel and Tieline codecs may occur during thunderstorm, even if the codec
is turned off but remains connected to the phone or ISDN system, LAN or the power.
ANY DAMAGE TO A TIELINE PRODUCT CAUSED BY LIGHTNING or an ELECTRICAL
STORM WILL VOID THE WARRANTY. Use of this product is subject to Tieline's
SOFTWARE LICENSE and WARRANTY conditions, which should be viewed at
www.tieline.com/support before using this product.
DIGITAL PHONE SYSTEM WARNING:
DO NOT CONNECT THE ANALOG POTS MODULE TO A DIGITAL PHONE SYSTEM.
PERMANENT DAMAGE MAY OCCUR! If you are unfamiliar with any facility, check that the
line you are using is NOTa digital line. If the Tieline codec becomes faulty due to the use
of a digital phone system, the WARRANTY WILL BE VOID.
WARNING:
HIGH LEAKAGE CURRENT. EARTH CONNECTION ESSENTIAL BEFORE CONNECTING
SUPPLY.
If the total leakage current exceeds 3.5 mA, or if the leakage current of the connected
loads is unknown, connect the supplementary ground terminal to a reliable ground
connection in your facility.
Supplementary ground connection
A supplementary ground terminal is provided on the codec to connect the unit to a ground
connection. The ground terminal has an M4 stud with M4 retaining nuts and is compatible
with all grounding wires. Remove only NUT 2 to connect your ground wire. The ground wire
must have a suitable lug. When refitting NUT 2 ensure that both NUT 1 & NUT 2 are
correctly tightened to establish and maintain a proper earth connection.

Important Note: To ensure the codec is added into Navigator correctly, when you add
the codec using the System 3rd Party Devices tab:
1. Ensure you use the identical Name and IP Address used to configure the device in
Razor software.
2. Ensure the codec is powered up and connected to the WheatNet-IP network.
3. After configuration the device should be displayed in the System pane in Navigator
software under a Blade.
4. Close Navigator software, remove power from the codec for 5 seconds and then
restore power.
5. Restart Navigator and test if codec sources can be routed to Blade destinations.
This is verified when green dots are displayed in the Navigator cross-point matrix.
Yellow cross-point dots indicate the Blade and Navigator haven't detected the
codec correctly. If this occurs, remove the newly added device, close Navigator
and remove power from the codec for 5 seconds. Then restore power to the codec
and add the device in Navigator again.
Only one codec should be added to Navigator at a time. For more information on the
WheatNet-IP system download Wheatstone user documentation via
