Proper use
Operating manual AOTDR - Version 04-2021A
Proper use
The reflecotmeter has been designed for measuring Silica-based
optical fibres for telecommunications. Do not attempt to use this
device for other applications. Misuse of the device may result in
electric shock, fire and/or serious personal injury. Modification of
the devices or use for any other purpose is not permitted, and will
immediately void any guarantee provided by the manufacturer.
Target group of this manual
The target group for installation and starting operation of the
ASTRO optical transmission technology are qualified experts who
have training enabling them to perform the work required in accor-
dance with EN 60728-11 and EN 62368-1. Unqualified persons are
not allowed to install and start operation of the device.

Important safety information
Operating manual AOTDR - Version 04-2021Apage 6
Important safety information
To avoid any hazardous situations to the extent possible, you must
adhere to the following safety information:
ACHTUNG: Failure to observe this safety information
may result in personal injury due to electrical and thermal
dangers!
Proper use
Only use the device at the approved operating sites and in the
ambientconditionsallowed(as described inthe following), and
only for the purpose described in the section “Proper use”.
Before starting operation of the device
HINWEIS: Read this operating manual attentively! It
contains important information about installation, ambient
conditions and maintenance of the device. Keep this operating
manual for future use and for handover in the event of a
change of owner or operator. A PDF version of this manual is
available to download on the ASTRO website (there may be a
more recent version).
Check the packaging and the device for transport damage
immediately. Do not start operation of a device that has been
damaged.
Transporting the device by the power cable may damage the
mains cable or the strain relief, and is therefore not permitted.
Danger of optical radiation
This product is laser class 1M (according IEC 60825-1 Safety of
Laser Products) and therefore several safety precautions must be
applied.
Exposure to class 1M laser radiation is possible on open
connectors or connected fibre patch cords. Do not view
exposed fibre or connector ends when handling or maintaining
optical equipment. Do not view with optical instruments into
open connectors or fibre ends on switched on devices. Make
sure all wherever a fibre inspection is required, that the
inspected fibre or connector is completely optical radiation
free.
Due to the high optical radiation and improper handling of
optical fibre connections and devices, there could be risks for
the operating and service personnel. Access should be
restricted to trained personnel only.

Never look directly or with optical inspection tools into the end
ofafibre whichis connectedtoatransmitteroropticalamplifier
and which is in operation. If the eyes are exposed to optical
radiation, which are above the acceptable maximum, this
could cause permanent damage to the eye.
Installation, operation, maintenance
The electrical connection conditions must correspond to the
specifications on the device type plate.
The ambient temperatures specified in the technical data must
be complied with, even when climatic conditions change (e.g.
due to sunlight). If the device overheats, the insulation used to
isolate the mains voltage may be damaged.
The device and its cable may only be operated away from
radiant heat and other sources of heat.
To avoid trapped heat, ensure there is good ventilation on all
sides.
No objects may be placed on the device.
The device does not feature protection against water and may
therefore only be operated and connected in dry rooms. It
must not be exposed to spraying or dripping water, to conden-
sation, or to similar sources of moisture.
All adhere to all applicable national safety regulations and
standards.
The device is operational when connected to the mains power
or if the provided Lithium battery is charged and inserted into
the battery compartment of the device.
Excess mechanical loads (e.g. falling, impacts, vibrations)
may damage insulation used to provide protection from mains
voltage.
High excess currents (lightning strike, surges in the power
utility grid) may damage insulation used to provide protection
from mains voltage.
If there is no information about intended use (e.g. operating
site, ambient conditions), or the operating manual does not
include the corresponding information, then you must consult
the manufacturer of this device to ensure that the device may
be installed. If you do not receive any information on this from
the manufacturer, do not start operating the device.
Verify that the product is set to match the available line
voltage, the correct fuse is installed, and all safety precautions
are taken.

Do not operate the instrument in the presence of flammable
gases or fumes.
Operating personnel must not remove instrument covers.
Component replacement and internal adjustments must be
made only by qualified service personnel.
Stop using the device when it malfunctions. (See section
„Maintenance and repair“).
Usersmustdisconnect theAC powercordfromtheAC adapter
inlet or the wall socket (outlet) immediately if they observe the
following or if the splicer receives the following faults: Fumes,
badsmell,noise,orover-heat.Liquid orforeign matterfalls into
cabinet. Splicer is damaged or dropped. If this occurs, ask our
service center for repair. Leaving the splicer in a damaged
state may cause equipment failure, electric shock or fire and
may result in personal injury, death or fire.
Use only the AC adapter / battery charger designed for this
splicer. Using an improper AC power source may cause
fuming, electric shock or equipment damage and may result in
personal injury, death or fire.
Do not disassemble or modify the device, AC adapter or
battery. In particular, do not remove or bypass any electrical or
mechanical device (e.g. a fuse or safety switch) incorporated
into the design and manufacturing of this equipment. Modifica-
tion could cause damage that may result in personal injury,
death, electric shock or fire.
Never operate the device in an environment where flammable
liquids or vapors exist. Risk of dangerous fire or explosion
could result from the splicer’s electrical arc in such an environ-
ment.
Do not use compressed gas or canned air to clean the device.
They may contain flammable materials that could ignite during
the electrical discharge.
Check the AC power source before use: Proper AC power
source is AC100-240V, 50-60 Hz. Proper DC power source is
DC10-12V. Improper AC or DC power source may cause
fuming, electric shockor equipment damage and may result in
personal injury, death or fire.
AC generators commonly produce abnormally high AC output
voltage or irregular frequencies. Measure the output AC
voltage with a circuit tester before connecting the AC power
cord. Such abnormally high voltage or frequency from a gene-
rator may cause fuming, electric shock or equipment damage
and may result in personal injury, death orfire. Make sure the
generator is regularly checked and serviced.

Do not modify, abuse, heat or excessively pull on the supplied
AC cord. The use of a damaged cord may cause fuming,
electric shock or equipment damage and may result in
personal injury, death or fire.
Do not short-circuit the terminals of AC adapter and optional
battery.Excessive electricalcurrent maycause personalinjury
due to fumes, electric shock and equipment damage.
Do not touch the device,AC power cord and AC plugs with wet
hands.Thismay result in electric shock.
Do not operate the device near hot objects, in hot temperature
environments, in dusty/humid atmospheres or when
water-condensation is present on the device. This may result
in electric shock or malfunction.
When using Li-ion battery, follow the instructions below.
Failure to follow these may result in explosion or personal
injury.
Do not charge battery with other methods than instructed.
Do not discard battery into an incinerator or fire.

Maintenance
 The operating display only shows whether the DC current,
which supplies the device components, has been
disconnected. However, operating displays (on the power
supply unit or the device) that are not lit up in no way indicate
that the device is completely disconnected from the mains.
Read carefully: EN 60728 - Part 1 Safety requirements: No
service work during thunderstorms.
Repair
Repairs may only be performed by the manufacturer. Improp-
erly performed repairs may result in considerable dangers for
the user.
If malfunctions occur, the device must be disconnected from
the mains and authorised experts must be consulted. The
device may need to be sent to the manufacturer.
