Introduction
The KI 025 Series Optical Talk Set is designed to provide convenient
full duplexvoice communication on one optical fibre.
The superb optical performance of the 1550 nm Laser version covers
all normal applications on singlemode or multimode fibre, enabling
long and short haul applications to be solved with a single model.
Other units are available, covering all possible wavelengths and
applications up to 200 kms.
Reliable field operation is guaranteed by a unique combination of
features such as very simple to operate controls, rugged drop proof
construction andreliable analoguetransmission.
Conferencing of 3 or 4 units may be achieved by using the dual
output ports.
The dual optical port is fully drop protected, and can be cleaned
easily in the field.
High quality duplex voice transmission is maintained over the full
optical range, with no operator intervention. An optical reserve of
typical 5 dB allows intelligible operation over very poor joints for
emergency use.
The hands-free 'speakerphone' is convenient for most users, and this
automatically changes to headset operation when the headset is
plugged in. For noisy situations, or intermittent use, a manual
transmit mode is available.
In any mode, a buzzer can be used to call the remote unit. The
same buzzer can be used asa 2 KHzsource for fibre identifiers.
Limits of Operation
This optical talk-set uses a sophisticated receiver arrangement to
provide operation over a very broad range of optical power, thus
giving the user great flexibility without the need to make adjustments.
If you have an optical attenuator available, try testing the audio
performance over a wide range of optical attenuation settings, eg. up
to 50dB ormore.
As the limits of performance are reached, the background noise will
become louder, and eventually the sound will fade altogether.
Note also that at very high loss levels, the set tends towards
half-duplex operation, and you will find that you will have to use the
headset, as the speakerphone will not operate properly.
Most users will find that the set operates well on both singlemode
and multimode fibres; however the greatest optical loss range will
apply to the correct fibre type.
Typical losses of a multimode-singlemode mismatch are around
10~13 dB, depending of fibre types and the mode field.
Other Kingfisher products include optical attenuators, return loss test
sets, light sources and power meter instruments.

General Safety Summary
Safety
These instruments contain no hazardous optical or electrical items.
The following information is for your reference:
When using this equipment, optical safety precautions should be
observed commensurate with the maximum available source power,
since most of this power can also be coupled out of the instrument.
Optical power levels in fiber optic systems can cause permanent eye
injury and damage to eyesight. Organisations and users operating
with these power levels MUST determine and observe relevant
safety precautions, which are beyondthescope of this manual.
Never look into the end of an optical cable or connector which might
be attached to an active source. Do not enable a laser when there is
no fibre attached to the optical output connector.
Optical magnifying instruments increase eye hazard. Always
disconnect the source before using an opticalmagnifier.
The laser module has a built-in safety circuitry which will usually
disable the optical output in the event of a fault condition, however
this cannot be guaranteed. An equipment assurance program is
recommended to check for safe laser operation.
This instrument is manufactured under an ISO9001 approved Quality
System, and conforms to CE Mark and C-tick EMC specifications.

Optical Connector
To install a through adaptor, align the locating slot on the side of the
through adaptor with that on the instrument connector, and press it
on.
To remove an adaptor, press the ‘red’ button on the upper edge of
the connector housing then pull off the adaptor. It can be much
easier to pull off the adaptor with a test lead in place, since this gives
better grip.
Different styles of connector adaptor can be easily fitted by the user:
ST, SC, FC, MU, LC/ F3000, E2000 / LSH, and LSA / DIN, SMA.
When not in use, keeptheconnectors covered and awayfrom dust.
Do not touch connector tips with your fingers, since body oils and dirt
can impair connector performance.
The supplied standard adaptors have ceramic sleeves to avoid
connector metal dust contamination. This contamination can cause
connector failure. Ceramic connector sleeves also work better in cold
conditions.
CAUTION! Do not use damaged or incompatible connectors.
The talk set is either PC or APC connector specific. This is
determined when ordering the instrument, and can only be changed
at the factory.
CAUTION! The use of bare fiber adaptors with the talk set is not
recommended as permanent instrument damage may occur.
How to clean the optical connectors
Always clean the mating connector tip and ferrule before mating,
using approved materials.
CAUTION! Do not attempt to clean an optical interface with anything
hard that could scratch glass, or permanent instrument damage may
occur.
WARNING! Be aware of and observe relevant optical safety
requirement procedures. Disable all sources when cleaning optical
interfaces.
Preferred Procedures
To clean the interface without removing the adaptor, you can use a
“stick” style connector cleaner for 1.25 or 2.5 mm ferrules. This
cleans both the adaptor and end face in one operation.
Alternatively first remove the interchangeable adaptor to access the
glass interface. Then blow away any dust or dirt with compressed air.
If this is not sufficient, then clean the interface by rubbing a lint-free
lens cloth overthe surfaceusingsmall circular movements.

Battery & External Power
This instrument is fitted with an internal rechargeable battery.
For operation of the instrument by external power, use Kingfisher AC
adaptor OPT103 (9V DC, 0.3 A,).
Suitable external powerpacks are easily available, andmust meet
the following requirements:
Rated for local mains supply voltage & safety requirements
Regulatedor unregulatedDC output 9 ~12V at 50mA max
Connectionpolarity: +ve pin
The instrument can also be charged from 12 V vehicle systems in an
emergency, however overcharging in this situation will reduce battery
lifesignificantly.
When the internal battery is low, a low-battery ‘Red’ LED indicator is
shown on the top panel.
a. Only start charging after the low battery indicator starts
operating.
b Do not charge for more than 10 hours.

Getting Started & Turning On
Powering Up
Check the compatibility of the supplied mains power unit with your
mains power supply. Check the setting of the 110/240 V selector, if
applicable. Connect the power unit to the mains, and plug the output
jack plug into the instrument power socket. If the battery is
completely fiat, you will have to wait a few minutes before the unit
becomes operable.
Connecting a Patch-cord & Turning On
To operate the system, you will need two instruments and a long
patch-cord. Clean the patch-cord connector, and plug it into the talk
set optical connector. For speakerphone operation, the two talk sets
need to be in different rooms, or separated by at least 10 metres, to
avoid acoustic interference. To turn the instrument on, turn the
volume knob, and set it mid-way. Upon turn-on you should hear a
tone emitted briefly which indicates normal operation.
Headset Operation
Set the rocker switch to Auto (on both instruments), plug in the
headset, and you should now be able to carry on a conversation.
Note that the 'XMIT' indicator shows that you are transmitting. If this
does not go on, the other person will not hear you.
Try also using the buzzer. Note that with the headset plugged in, the
built-in speaker is silent, however the buzzer will cause the speaker
to sound, alerting the user to put on his headset.
If therocker switch is set inthemid position, youwill be able to listen,
but not transmit. In this mode, push the 'Manual' function to transmit.
This feature can be useful in very noisy situations, to avoid spurious
transmission.
Speakerphone Function
To try testing the speakerphone function, unplug the headset. You
should now be able to operate the unit as a half duplex
speakerphone. Note that if you are talking, and the unit is
transmitting, then youwill hear the other person until he/she 'cuts in'.
In the speakerphone mode, you can also use the rocker-switch to
select auto ormanual operation.
‘Party Line’ Conversation
To use more than 2 talk sets in a communication link, you need to
use the second optical output connector connected to an additional
talk set.
The number of units that can operate is limited by the fact that each
individual unit reduces the available operating performance by about
7 dB. For this kind of use, headset operation is preferable, since the
half-duplex speakerphone is difficult to use when several people are
involved.
As long as the units are turned on, their buzzers will still operate to
call people to a conversation.

KI 025 UM-5

Getting Started & Turning On
It’s as simple as:
Turn the unit on, and set the volume
Plug in the fibre
You can now receive calls or hear the buzzer
Set transmit to auto or manual
Speakerphone operation is now fully functional
The buzzer is independent of all other controls
If you want to use a headset – just plug it in

Care of your Instrument
Environmental
This equipment is ruggedly constructed with a cast aluminium frame,
which will take normal wear and tear. The internal pcb is also
mounted in a shock absorbing arrangement and the panel controls
are protected when the instrument fails face down.
The unit is designed to be reasonably dust & moisture resistant, with
a plastic waterproof speaker etc. However, if water gets into the
microphone, it may stop working until it dries out again. If the
microphone is damaged, see the maintenance section for
replacement.
Avoid leaving the unit in direct sunlight, where it can get very hot.
Take note of the section 'Optical Connector' in relation to the optical
connector, and ‘Battery and External Power’ for power requirements.
Please note that the instrument is not waterproof, so exposure to
liquids should be avoided if possible. The (optional) carry case is
hose-proof and dustproof, and provides complete protection.
Tips on PortableUse
When using the instrument in a mobile situation, a few turns of the
patch-cord around one of the handles provides strain relief for the
optical connector.
The instrument is fully operational without removal from the carry
case, which provides excellent protection in normal use.
