Safety Instructions: T-BERD/MTS 5800 and TEM
23 November 2016 21148865, Rev 003 Page 3
The instruments supported by these instructions are designed to be used to test non-hazardous circuits
with voltages less than 42.4 V peak and 60 VDC.
You must be responsible for your own safety by employing proper safety procedures to minimize the risk of
electrical shock. Comprehensive safety training is beyond the scope of these instructions. Still, you should
read and understand all safety information within before using these products.
When using the product, basic safety precautions should always be followed to reduce the risk of fire,
shock, and injury to persons, including the following:
1. Read and follow all warning notices and instructions marked on the product and included in the
manual.
2. Use only the AC Adapter/Charger supplied with the product. Do not use AC Adapter/ Charger
outdoors or in wet or damp locations. Connect the AC Adapter/Charger to the correct mains voltage
as indicated on the ratings label.
3. Do not allow anything to rest on the power cord, and do not locate the product where persons can
walk on the power cord.
4. This product is intended to be used with a 3-wire grounding-type plug (a plug that has a grounding
pin). This safety feature is vital to the safe operation of the instrument. Do not defeat the purpose of
the grounding-type by modifying the plug or using an adapter.
5. Do not use telephone equipment (other than cordless) during a lightning storm. There is a
possibility of a nearby lightning strike, which could exceed the capacity of the telephone network
protective devices and harm you.
6. Do not use telephone equipment in the vicinity of a gas leak or in any explosive environment. This
tester, and most other telephone equipment, could in normal operation generate a spark strong
enough to ignite a fire or explosion.
7. Do not touch or otherwise come in contact with telephone conductors that could be exposed to
lightning or accidental connection to power circuits without first isolating them from the telephone
network.
8. Do not install telephone equipment or terminations (jacks) in wet locations unless the equipment or
termination is specifically designed for such locations.
9. Do not cause or allow telephone or telecommunication circuits to come in contact with power
circuits (mains).
10. Do not attempt to service this product yourself, as opening or removing covers may expose you to
dangerous high voltage points and other hazards. Refer all servicing to qualified service personnel.
11. The 5800 WiFi module complies with the FCC RF radiation exposure limits set forth for an
uncontrolled environment. For body worn operation, this equipment has been tested and meets the
FCC RF exposure guidelines when used with an accessory that contains no metal and that
positions the handset a minimum of 0cm from the body.
12. Use appropriate cables when connecting to telecommunications circuits. Putting an RJ-11
connector in a RJ-45 port can damage the RJ45 port.
13. WARNING: Danger of extreme heat, fire, or explosion if battery is tampered with. Replace only with
Viavi approved Li-ION battery. Dispose of used batteries according to the manufacturer's
instructions.
