4. Warranty
Your CTH-8550 is guaranteed for one full year, parts
and labour, against any breakdowns or component
failure, as is the tradition in Switzerland for such
equipment.
As we see it, any warranty longer than 1 year is the
obvious sign of inferior quality and design,
indicating that a failure could arise anytime.
Any component either will fail within days or will
last "forever".
This is the reason why all our machines are
thoroughly broken in before being lovingly packed
and sent to you.
We are still fully aware that no component is always
flawless, and that a problem could arise anytime
after the warranty period.
In such a case, we will carefully examine every
situation, with the aim of reducing the likely repair
costs to minimum levels. You can always trust us for
customer care, as you already trusted us when
purchasing your CTH-8550.
The warranty is valid in the original country of
purchase only.
Warranty is transferable to a single second hand user
within the first year, provided the country will
remain the same.
5. Installation
5.1. Unpacking
Please remember how your CTH-8550 was packed.
It will be very useful in case of move.
Your CTH-8550 has been carefully inspected and
packed prior shipping. Be sure you will receive your
carton box in mint condition, without any signs of
external damage.
If you would notice any packaging problem, please
immediately report to your official dealer!
Any future shipping must be done in the original
carton box. Any warranty rights will be void if the
CTH-8550 is not shipped/returned in its original
package.
Your carton box must contain:
The CTH-8550
The IRC-885 infrared remote control
The darTZeel USB key
The AC power cable related to your country

5.2. Location
Before making the first connection, you should think
carefully about the location where you are going to
put your gear. If you planned to fit your darTZeel
CTH-8550 into furniture, please bear in mind that
you must allow at least one inch of free space all
around the unit, for proper cooling.
As said in the “Brief description” chapter, the
CTH-8550 runs quite in a cool way. However, as
long as one dissipates an even low thermal power,
not allowing proper ventilation will quickly rise the
internal temperature.
If you do not respect this, the CTH-8550 may stop
playing if it becomes too hot.
The heat sinks shutdown point is at around 70°C,
and the power supply starts up again when the
temperature has dropped to 60 °C.
Please also note that permanent excessive temperature
will reduce the life span of your machine
Anyway, if possible, always leave enough space
around your darTZeel CTH-8550, allowing you to
gain easy access to it when making connections.
5.3. Connections
As you will see in next chapter, connecting the
CTH-8550 is quite easy, thanks to its clearly labelled
rear panel.
The only thing you will have to check is proper voltage
settings. You will find above the IEC connector a
small window showing the voltage selection.
Please read chapter 6.2.1 about this topic.
Speaker binding posts can accept most types of
connection. In case you will use speaker cables
terminated by spades lugs, be sure not over tighten
speaker posts. Over tighten will create some play
and could lead to loosen speaker posts.
If you have the choice, prefer spring loaded banana
plugs. Our experience showed that they bring very
reliable contacts over the long haul, without needing
to be periodically re tighten.
As soon as the CTH-8550 will be plugged into the
AC wall outlet, the operation status LED will go red.
There is no general hardware on/off switch.
We do hope you will nevertheless still sleep well,
knowing that the CTH-8550 consumption is less
than 3 watts when powered off.
