Protect Against Lightning and Power Surges
When the TDR60 is installed, have the professional installer ground the system to protect against
voltage surges and built-up static charges. For information on grounding standards for electrical and
radio equipment, refer to the electrical code in the country of installation.
Protect the TDR60 from lightning and power-line surges during a storm by unplugging it from the
wall outlet and disconnecting the coaxial cable.
Provide Antistatic Protection
Wear a properly grounded antistatic wrist strap to prevent electrostatic damage to components when
handling circuit boards or other electronic modules.
Turn the TDR60 Off When Changing Circuit Boards
Turn the TDR60 off before installing or removing any circuit boards from chassis slots. Possible
damage may occur to modem, boards, or related equipment if power is left on during this procedure.
Non-replaceable Lithium Battery
The lithium battery is not placed in an operator accessible area. The battery is part of an approved
semiconductor and is not replaceable.
Keep Objects Outside
Touching internal TDR60 parts is dangerous to both you and the unit. Never put any object,
including your fingers, through slots or openings, as this could result in touching dangerous voltage
points, short-circuiting parts, electric shock, or fire.
There are no user-serviceable parts inside the TDR60. If an object falls into the equipment, unplug
the unit and contact Tiernan Customer Service, as serious damage could occur to the TDR60 or its
components.
Use Approved Attachments Only
Use only Tiernan-approved option cards and equipment with the TDR60.
Clean the TDR60
Before cleaning the TDR60, unplug it from the wall outlet. Do not use any type of abrasive pads,
scouring powders, aerosol cleaners, or solvents such as alcohol or benzene.
Use only a clean, soft cloth lightly moistened with a mild detergent solution. Wipe all equipment
with a clean, soft cloth lightly moistened with water to remove the detergent solution.
Service the TDR60
Do not attempt to service the TDR60 yourself, as there are no user-serviceable parts. Opening or
removing covers may expose you to dangerous voltages or other hazards as well as void your
warranty. Contact Tiernan Customer Service to obtain qualified service personnel.
The following conditions indicate that the equipment needs servicing:
■
The power cord or plug has been damaged.
■
An object has fallen into the TDR60.
■
Liquid has been spilled into the TDR60, or it has been exposed to rain or water.
■
The unit has been dropped or the cover has been damaged.
■
The TDR60 does not operate normally, or it shows a marked change in performance.
Perform Safety Checks
Upon completion of any service or repairs to the TDR60, ask the service technician to perform
safety checks to verify that the system is in safe operating condition.
