INSTRUCTIONS FOR INSTALLATION
To obtain the best results and optimum performance,
follow the instructions for correct installation provided in
this manual. Failure to follow the instructions and apply
therulesindicatedmaycausemalfunctionoftheappliance
and relieves the manufacturer, OLIMPIA SPLENDID of
anyformofguaranteeandliabilityfordamagestopersons,
animals or property.
Theelectricalsystemmustcomplywiththeregulations
and rating data in the technical sheet, with good
grounding.
SELECTION OF POSITION OF THE UNIT
The position for installation of the inside unit, to obtain the
bestperformanceandpreventbreakdownsorhazards,must
have the following requisites:
- The bottom of the inside unit must be at least 2 meters
off the floor and no more than 3 (fig. 1)
- The wall on which the inside unit is installed must be
sturdy and able to withstand its weight.
- Itmustbe possibletoleave roomaroundthe unitfor any
maintenance operations that may be necessary.
- There should be no obstacles to the free circulation of air on
theintakesideand,especially,ontheairoutletside;onthisside,
in particular, there should be no obstacles closer than 2 m.
Thiscould causeturbulence thatwouldinterferewithcorrect
operation of the unit.
The air conditioner must be installed on a wall that
communicates with the outside.
Caution: After determining the best place for
installation as described above, check to make sure
that the wall can be drilled in that point without
interfering with other structures or installations
(beams, piers, pipes, wires, etc.).
Check again to make sure there are no obstacles to
air circulation through the holes to be drilled due to
plants and their leaves, slats or panelling, blinds,
gratings or grids too dense, etc.).
Before installing the air conditioner, it is essential to make
an accurate calculation of the heat load in summer (and
cold load in winter for models with heating pump) at the
site of installation.
The more accurate this calculation is made the better the
air conditioner will be able to do its job.
Tomake thesecalculations, referdirectlytotheregulations
in effect (UNI ref. Law 10/91) or to the tables, both printed
and computerized, based on those regulations.
For particularly significant applications, we recommend
contacting expert heating engineers.

As far as possible, in any case, it is important to try and
reduce major thermal loads by the following means:
Largeglass panes exposedto sunlightshould beprovided
with curtains on the inside or shades on the outside
(Venetian blinds, verandas, refracting films, etc.)
The air-conditioned room should be closed as much of
the time as possible.
Halogenspotlightsor other electricalequipment with high
power consumption should not be used in the room
(toasters, steam irons, hot plates for cooking, etc.).
- Itshouldnotbeinstalled ina positionwheretheairflow

- Itshouldnotbedirectlyoveranotherappliance(television
set, radio, refrigerator, etc.), or over a source of heat
(fig. 3).
- There should be no obstacles for reception of signals
emitted by the remote control (fig. 4).
Thisoperation shouldbecarriedoutusingtheproper tools
to facilitate your work and prevent excess damage or
disturbance to your client.
The best tools for drilling large holes in walls are special
drillscalledcore borers withveryhigh twistingtorqueand
adjustable rotation speed depending on the diameter of
the hole to be drilled.
Toprevent thecreation oflargeamountsofdust andrubble
due to drilling, the core borer can be fitted with a vacuum
system applied by means of suction cups to the drilling
zone.
Our Service Department can give you all necessary
information to enable you to find these devices.
To drill the holes, proceed as follows:
Fasten the drilling template to the wall leaving the
necessary space from the ceiling, floor and side walls as
shown on the template. Use adhesive tape to fasten it in
place.
Use a small drill or punch to mark, with extreme care, the
exact centre of each of the holes to be drilled.
Using a core boring head measuring at least 154 mm to
drill the two holes for entry and exit of the air.
Note: The holes should have a slight outward
inclination to prevent any backflow of water from the
pipes (see fig.1).
Most of the removed material is expelled outwards,
therefore make sure that it does not hit any person or
object when it falls out.
In order to avoid as much as possible outer plaster
breaking, it is necessary to proceed carefully with the
last part of hole execution, decreasing pressure on core
borers.

Next, drill the holes for anchoring the fastening brackets to
the wall using as a first option the 4 holes on the ends of
the bracket as shown on the drilling template (see fig. 6).
If the wall is not very solid, it is advisable to use some
extra anchor bolts.
As you can see, the bracket can be fastened in a number
of different ways and positions. The air conditioner is
heavier on the left-hand side, so it is best to make sure of
asolidanchorage onthatside.Theanchor boltsprovided
require holes with a diameter of 10 mm. In any case, the
wall should be inspected carefully to determine the best
possibleanchorage andtypeofboltssuitableforparticular
situations.
Warning: The manufacturer is not liable in case of
underestimation of the structural consistency of the
anchorage made at the time of installation. We
therefore recommend that you perform this operation
with the maximum care as, if not done properly, it
can cause serious damage to persons and property.
When installing models equipped with heating pump, if
no drainage well for condensate has been provided built
into the wall (see paragraph 2.3.2), it will be necessary,
to allow for drainage of the condensate, to drill a hole
through the wall measuring 16 mm in diameter in the
position shown on the template (see fig.6).

33 UNICO-HE
When the machine is heating, it produces condensate
that has to be eliminated through a specific drain line,
otherwise the machine will not work. Drainage occurs by
gravity. For this reason, it is essential for the drain line to
have a minimum inclination of at least 3% throughout its
length. The pipe can be rigid or not, with a minimum
internal diameter of 16 mm.
Ifthe linedrainsintoasewersystem,it shouldbe provided
with a trap ahead of the main outlet.
The trap should be at least 300 mm lower than the inlet
opening on the air conditioner (fig. 7).
If the drainpipe drains into a vessel (tank or other
container), this container should not be sealed and the
drainpipe should not remain immersed in the water (see
fig. 8).
The correct position for the pipe inlet on the machine is
shown on the template for drilling and positioning the
machine (see also fig. 6).
Theair conditionerisequippedwithapipewithanexternal
diameter of 14 mm for drainage of condensate.
Thispipeprotrudesfromthe machineforalengthof about
400 mm.
The pipe should be fitted inside the one provided by you
foradistance ofat least200mm,withoutanysharpbends
that could obstruct it.
When draining toward the outside, the pipe can be
inserted through the wall (always making sure to give it a
suitable inclination) (see fig. 5).
Caution:makesure,inthiscase, thatthewaterexpelled
outward does not damage or disturb persons or
property. During the winter this type of drainage may
cause sheets of ice to form.
After drilling the holes, the plastic pipes supplied with the
air conditioner have to be fitted through them. The pipe
with insulation on the inside has to be fitted in the right-
hand hole with the insulated part toward the inside as
indicatedonthe labelappliedto it.Thelength of thepipes
should be 55 mm less than that of the wall. To cut the
pipe, a normal handsaw can be used. After cutting the
pipes, fit the ends into the two internal anchoring flanges
(fig. 10).
The tube diameter is nearly the same as those carried
out using the 152/154 mm nominal diameter core drill. In
orderto introducethetubes,theymustthereforebe forced
slightly using, in the most difficult cases, a normal rubber
hammer (fig. 10/1). Having the hole internal diameter
extremely similar to the tube external diameter avoids
dangerous slacks which may generate humidity
infiltrations or air noises. Should the insertion prove to be
too difficult, we suggest you drill using the core bit inside
the hole so as to widen the internal diameter slightly.
Next, fit the pipes into the holes in the wall and fasten the
flanges with 4 anchor bolts with diameter 6, taking care
to keep the two fastening holes in a horizontal position.

To position the external grating, proceed as follows:
- Grasp the two rubber belts attached to the grating in
one hand.
- Fold the outer gratings in half by grasping them with
your free hand along the fold line and inserting your
fingers inside the fins (fig. 11).
Insert your arm inside the pipe until the grating
protrudes all the way outside.
- Let the grating open, but keep your fingers inside the
fins.
- Turn the grating so that the fins are perfectly horizontal
with the inclination toward the outside (fig. 12).
- Pull the grating toward you.
- Tighten the rubber belts and fasten them to the two
pins on the inner flange.
- Cut the excess part of the belt.
Warning: If the external grating is accessible, to
prevent the hazards resulting from its possible
removal (insertion of the hands into the pipes and
touching moving or powered parts) it is absolutely
essential to fasten it to the wall with 4 anchor bolts
with a diameter of 6 mm.
Theairconditioner isequippedwith apowersupply cable
and plug.
If it is installed near an outlet, you need only plug it in.
In this case, it is important to make sure the outlet to
which you are plugged in is effectively grounded and
connected to the mains by wiring of adequate size
(minimum 1.5 sq.mm. cross section).
To make an electrical connection with the shielded cable
(recommended for installations high on the wall) proceed
as follows:
Install a shunt box in the wall in the position shown on
theinstallationtemplate (fig.6), whereyoushould provide
apowercablewitha cross-section(twopolesplusground
wire) of 2,5 sq.mm.
Warning: The external power line should be provided
withan overloadcircuitbreaker withsuitablecapacity
for the rating of the machine.
Make all connections in compliance with the laws in
effect.
Close the shunt box with its cover after drilling a hole in it
for passage of the cable.
Alternatively,you canuseacableinthewallinthe position
shown on the template, for making the connection. In
this case, remove the casing (as described in paragraph
2.4.2)andconnect thecableto thepowerterminal board.
Caution: these operations should be performed with
the machine already positioned on the bracket. Read
the instructions carefully before completely the
electric connection.

Afterchecking againthatthe fasteningbracketis securely
fastenedtothe wall, andthatanynecessary preparations
for electric connection and condensate drainage have
been made, you can fasten the air conditioner to its
supportingbracket. Liftitupholdingthesidesofthebottom
(see fig. 13).
To facilitate the operation of fastening it to the bracket, tilt
it slightly toward you.
Tomake theelectricalconnectionandfastenthedrainpipe,
place a wedge between the air conditioner and the wall
(see fig. 14).
After these operations have been carried out, the air
conditioner can be pushed firmly against the wall so that
the bottom hook catches.
When you have finished, inspect carefully to make sure
there are no fissures at the back of the air conditioner
(the insulating gasket must fit firmly against the wall)
particularly in the zone where air enters and leaves the
machine.
PREPARATIONFORASSEMBLY/INSTALLATION
WALLTOPPART
The air conditioner is assembled in the factory ready to
be installed low on the wall.
Theair outlet,in thiscase, isat thetopoftheairconditioner
with the recycle grating and control panel.
In order to prepare the product for installation on the top
part of the wall, follow the instructions below.
Note: if the air conditioner has not been installed on
the wall yet, place it on its back. To not apply heavy
pressure to the bottom of the device as this could
dent or scratch the casing.
Use a small blade screwdriver to remove the horizontal
strips on the casing, applying gentle leverage in the slits
along the sides. (see fig. 15).
Take care not to scratch the strips or casing with the
screwdriver point.
Unscrewthe 8self-threadingscrewsthatfastenthecasing

you will find two holes on the base (see fig. 18-19).
Make sure the connection plate is securely fastened on
theinsideoftheair conditioner, andapply someinsulating
tape if necessary. Remove the styrofoam enclosure on
the lower right-hand side under the air recycle fan and fit
it against the opening above the fan (see fig. 20-21).
Remove the air outlet grating by removing the fastening
screws. Remove the control panel (see fig. 22).
When performing this operation place the casing on a
secure surface so as not to scratch or dent it. Remove
the plastic plate with the logo and transparent screen for
display of the leds from the control panel by pressing on
the hooks at the rear. Turn it over (rotate by 180°) and
reinstall it on the panel.
Reassemble the parts in the opposite position from the
original installation, reversing the air outlet grating with
the control panel grating.
Turn the casing over so that the air outlet grating is on
the lower right-hand side of the device.
Connect the plug on the step-step motor of the grating.
Fit the casing back on the air conditioner carefully, taking
care to hold the wires for the step-step motor to one side
so that they do not interfere with the inner part of the air
outlet grating.
Check that all the coupling references of the casing with
the rear frame are fully inserted so that the casing is
fitted smoothly and evenly all around.
Fasten the casing with its eight screws and replace the
strips in their slots.
After completing installation, the electronic parts of the
air conditioner have to be configured so as to take into
account the stratification of heat in the room. This proce-
dure is outlined in paragraph 2.5 (Operating tests and
diagnosis of possible malfunctions).
WORKING TESTS AND IDENTIFICATION
OF POSSIBLE MALFUNCTIONS
The program introduced in the microprocessor of this
device makes it possible to run a brief self-test to ensure
that the machine functions normally by starting each of
its internal components.
To run the self-test, proceed as follows:
- Power the air conditioner and make sure it is on stand-by.
- Use a sharp object to press the microkey located under
the hole on the left of the control panel for at least 10
sec.
- At the beginning and end of the self-test procedure the
status of configuration of the machine will be displayed
for a few seconds as follows:

equipment heats normally (if equipped with heat pump
function) for about 2 minutes and then, after a few
seconds, that it cools for another 2 minutes.
Beforeconcludingthe self-test,the electronicparttests

normally. If any of these should not be working, the
corresponding signal led remains lit for 20 sec. (see
table on next page).
Should there be a jam in the air-conditioning system with

be ready to refer to the Service Centre which leds are
blinking in order to simplify their intervention.
Starting from the left:
The end of the self-test will be signalled by all the leds
lighting up at once and blinking ten times, as well as by
an acoustic signal.
At this time, you can adjust the temperature reading on
theroomtemperature sensor. Thiscorrectionis important
if the air conditioner is installed high on the wall in a room
where the warm air tends to stratify upward (as in rooms
with high ceilings or other sources of heat besides the air
conditioner).The sensorwill reada temperature3°C lower
than the effective one, in this case, to compensate for
the difference between the lower inhabited part of the
room and the temperature at the height of the sensor.
To enter or remove this correction proceed as follows:
1 Check the status of the machine as described
previously, and if no correction has been made, press
the button on the console while the acoustic signal is
on at the end of the self-test.
2 To remove the correction, press the button while the
acoustic signal is on at the end of the self-test.

The machine is set in the factory without correction of
the temperature.
In addition to the self-test (that can be made under any
conditions of room temperature) we recommend that you
also test the product in the various operating modes
accessible to the user (see the user manual). One
important test you should make concerns regular
evacuationof condensationwateronthemodelswithheat
pump. To check this, keep the machine running for at
least 4-5 hours in the heating mode. If the water does not
drain, there should be an “overflow” alarm.
Ifthereshould bea malfunctioninthe condensationwater
drain system, the air conditioner stops working and
signals, with flashing orange, green and red lights (the
second and third leds from the left), the alarm status.
To enable the air conditioner to work temporarily until the
service personnel arrives, you can drain the water out by
following these simple instructions:
- Grasp the rubber cap on the bottom centre of the air
conditionerbehindthe edgeofthe framefacingthe wall
between your thumb and forefinger.
- Pull the rubber tube closed by the cap out by a few
centimetres.
- Removethe capafterplacingabucketorothercontainer
underneath it (at least five litter capacity) to collect the
water (see fig. 23).
- After eliminating the malfunction the service personnel
will take care of closing the evacuation tube.
PERIODICAL MAINTENANCE
Air conditioners of this type do not require any particular
routine maintenance except:
- Cleaning or washing the room air filter when the red
led lights up (see user manual).
- Cleaningof“externalair”battery,tobe doneasneeded,
depending on the amount of dirt in the external air,
once or twice a year. To do this, you must, of course,
open the air conditioner by removing its casing and
the noise insulation on the inside.
- Cleaning can be done using a vacuum cleaner or soft
brush, taking particular care not to damage the
aluminiumheatexchanger baffles.Itmay benecessary
to use water and detergents to remove heavily
encrusted dirt.
Note: after cleaning the battery replace the noise
insulation carefully matching the edges and gaskets
with their reference markings.
Beforeyouleavethe site ofinstallationyou should gather
up all packing material and use a damp cloth to remove
any traces of dust that may have deposited on the
machine during assembly (fig. 24).
These operations, though certainly not essential, have a
beneficial effect as they enhance the professional image
of the installer in the eyes of the client.
To preventunnecessary callsby theuser, beforeyouleave
the site of installation it is also a good idea to:
- Explainthecontents ofthe InstructionManualto theuser.
- Show him how to clean the filter.
- Explain when and how he should contact the Service

Important Recommendations
Installationandconnection oftheairconditionershould
be carried out by specialized personnel in possession
of the qualifications specified in Law 46/90.
The instructions for installation are provided in the
specific manual.
Nostructural object(furniture, curtains,plants,leaves,
blinds, etc.) should ever obstruct the normal flow of
air from either the internal or external gratings.
Never lean or, worse yet, sit on the casing of the air
conditioner as this could cause serious damage to
the external parts.
Do not turn the horizontal airflow baffles by hand.
Always use the remote control to adjust baffle
position.
If the unit leaks water, switch it off immediately and
disconnect it from the power mains. Call the nearest
service centre.
When the air conditioner is heating, it has to
periodically eliminate any ice that could form on the
external battery. While it is doing this, the machine
keeps running but does not heat the room. This lasts
for a brief period of time, from 3 to a maximum of 10
minutes.
The air conditioner must not be installed in rooms
where explosive gasses develop or where there are
conditionsof heat andhumidity beyondthe maximum
limits indicated in the installation manual.
Clean the air filter periodically, as described in the
specific paragraph.

CONTROL OF AIR CONDITIONER
USING THE REMOTE CONTROL UNIT
The remote control supplied with the air conditioner is
designed to be extremely sturdy and to ensure excellent
performanceinuse,butitshouldnevertheless behandled
with some care.
For example, do not:
- leave it out in the rain, spill water on its keyboard
or drop it into water.
- subject it to impacts or drop it onto hard surfaces.
- leave it exposed to direct sunlight.
- place obstacles between the remote control and
the air conditioner while using it.
Furthermore:
- if other devices operated by remote control (TV, radio,
stereo systems, etc.) are located in the same room as
the air conditioner, there may be interference,
- electronic and fluorescent lighting may interfere with
communications between the remote control and the
air conditioner,
- remove the batteries in case of prolonged disuse of
the remote control.
Useonly 2dry cellbatteries typeLR03 with1,5 V(supplied
with the remote control unit). Dispose of used batteries
only at the special collection points provided by the local
authorities for this type of waste.
Replace both batteries at the same time.
To insert the batteries remove the spring-latch cover on
the back of the remote control.
The batteries have to be inserted according to the positi-
veandnegativepolemarkings inthebottomofthe battery
compartment.
Close the spring-latch cover after inserting the batteries.
REMOTE CONTROL
The remote control is the interface between the user and
the air conditioner. It is therefore particularly important to
familiarize yourself with the parts of the remote control
that relate to this interface.

The remote control is also equipped with a cover with a
cursor that can be positioned so as to permit access only
to the ON/OFF, AUTOMATIC MODE and NIGHT MODE
buttons.
With the cover in this position the air conditioner can be
used but none of the settings can be tampered with.
In order to command the machine via the remote control,
the main switch on the electric line (ask the technician
whoinstalledthe machineaboutthemainswitch position)
must be on and the mains plug of the machine must be
plugged in.
Once these operations have been carried out, the
machine may be regulated using the remote control.
To send commands to the air conditioner, point the front
of the remote control toward the air conditioner control
panel.
The device emits a beep when it receives a command.
The maximum distance for transmission of commands is
about 8 meters.
This button turns the machine on or off.
The machine’s control system has a memory, therefore
any setting will not be lost when it is turned off.
This button serves to switch the air conditioner on or off
for brief periods of time.
In case of prolonged stop of the machine, it must be
deactivated turning the main switch off or unplugging the
machine from the mains.
By means of this button the machine is automatically
regulated in order to create an optimal comfort tempera-
ture in the air-conditioned room.
The machine’s temperature is automatically regulated
according to the room’s temperature.
The fan speed is also automatically regulated according
to the set temperature (except in dehumidification use).
Whenusedinthis mode, theairconditionerdehumidifies
and cools the room.
Button T4 is used to select the operating mode.
Press until the snowflake symbol appears on the display.
First set the desired temperature and fan speed (see the
relative paragraphs).
After three minutes (maximum time), the compressor
shouldstartup andtheairconditionershould startcooling
the room.
When the compressor starts you will see a green LED
light up on the control panel.

When used in this mode, the air conditioner only
eliminates the humidity in the room, practically without
changing the temperature.
This function can be extremely useful between
seasons, particularly on rainy days when the tempe-
rature is not uncomfortable but the excess humidity
feels unpleasant.
When used in this mode, the air conditioner ignores
the temperature and fan speed settings, which are
not shown on the display in this case.
To operate the air conditioner in this mode, press
Button T4 until the droplet symbol appears on the
display with automatic ventilation.
In this operating mode it is normal for the air
conditioner to function intermittently.
When used in the mode the air conditioner does not act
on the either the temperature or the humidity in the room,
but only keeps the air in circulation.
This operating mode is selected by pressing button T4
until the fan symbol appears on the display.
At this stage you can select the fan speed (see
paragraph 3.4.10).
When used in this mode the air conditioner heats the
room. This function is only available on models with a
heating pump (HP).
To select this mode press button T4 (operating mode
selection switch) until the sun symbol appears on the
display. First set the desired temperature and fan speed
(see the specific paragraphs). After three minutes
(maximum time) the compressor should start and the air
conditionerstartsheatingtheroom.Whenthecompressor
starts you will see a green LED light up on the control
panel.
Note: The air conditioner has to defrost its battery
periodically (about once every half hour). During this
operation(about 3-8minutes)the airconditioner does
not heat the room, though its internal parts remain
on except for the room air fan. When the outdoor tem-
peratureis verylow,there maybeaslightdelay(about
three minutes) for passage from the minimum to the
medium or maximum speed from when the command
is sent to the machine with the remote control.
The airflow can be controlled in both its horizontal and
verticaldirection. Controlofthehorizontaldirection cannot
be carried out with the remote control and must be made
manuallybyadjusting thepositionof the finsonthe outlet
opening.
IMPORTANT: Adjustment of horizontal airflow should
only be made when the movable grating is not m
oving.

To adjust vertical airflow you can operate in two ways:
- continuous oscillation of airflow, obtained by pressing
button T9 which starts and stops the movable grating.
This enables the fins on the grating to turn completely
around.
- stop the movable grating in the desired position by
pressing button T9 again while the fins are in motion.
PressingbuttonT9willstartautomaticturning ofthebaffle.
IMPORTANT: The baffle must not be turned by hand.
Fan speed is controlled by button T5.
Pressing this button gives the following sequence:
once=Low, twice=Medium, three times=High, four
times=Automatic.
The higher the speed setting, the greater the output of
the air conditioner but also the louder its operation.
If you selectAutomatic mode, the microprocessor in the
air conditioner adjusts the speed automatically, keeping
it as high as needed to reach the temperature setting
with respect to the effective room temperature.
As the room temperature nears the setting, fan speed
is reduced automatically.
When the unit is operating in dehumidification mode,
fan speed adjustment is not possible as it can only
function at low speed.
This function is available only on devices equipped with
the optional external air intake, that is an exclusive
feature for this type of air conditioner.
Press button T8 once to start the microfan on the
external air intake and open the shutter to refresh the
air in the room.
Press button T8 again to close the shutter.
It should be borne in mind that opening the external
air intake reduces the cooling effect of the air
conditioner.
This is also true of the heating effect for machines
equipped with a heat pump.
For this reason, if you want to maintain a constant flow
of external air with the air conditioner in operation, you
should first make sure your unit is powerful enough to
operate this way.
If not, you should close the external air intake when
the temperature outside is extreme.

Use button T3 to select Night well-being Mode, which
includes the following functions:
- Gradual increase of the temperature set for cooling.
- Gradual reduction of the temperature set for heating
(only HP models).
- Reduction of noise level.
- Lower energy consumption at night.
To select Night well-being mode press button T3 after
selecting the operating mode using button T4 and
setting the temperature using button T7.
Ideally, you should start night well-being mode
operation just before you fall asleep.
In cooling mode, the set temperature is held for one hour
after starting Night well-being mode operation.
For the next hour, the setting is allowed to increase
gradually up to 2°C over the original setting, while the fan
speed setting is low.
After the second hour, the temperature and fan speed
settings are not changed.
In heating mode, the set temperature is held for one hour
after starting Night well-being mode operation.
For the next hour the setting is lowered gradually to 4°C
below the original while the fan speed setting is low.
After the second hour, the temperature and fan speed
settings are not changed.
Night well-being mode operation is not available for
dehumidifying only.
Night well-being mode operation can be halted at any
time (ideally when you wake up in the morning) by
pressing button T3 again.
At this stage the temperature and fan speed settings
made prior to starting Night well-being mode operation
go back into effect.
The air conditioner logic provides the user with a choice
of two operating programs that can be set to start and
stop at programmed times, for example you might want
the air conditioner to start shortly before you return home
so that it is cool when you get there.
To usethesefunctions itisfirst necessarytoset the exact
time on the remote control and then set the time for the
programs to start.
To set the exact time proceed as follows:
a) Press buttonT6 Time and Program Setting, as many
times as necessary to display the hour indicator (H).
b) Press the toggle button T7 to increase or decrease
the numerical display until it shows the exact hour.
c) Press button T6 again to display the minute
indicator (M).
d) Press toggle button T7 to increase or decrease the
numerical display until it shows the exact time in
