SAFETY INSTRUCTIONS
•Always read the safety instructions carefully.
•Keep this Manual for future reference.
•Keep this equipment away from humidity and dust.
•Lay the equipment on a reliable flat surface before setting it up.
•The openings on the enclosure are for air convection, hence protecting the equipment from
overheating. DO NOT COVER THESE OPENINGS. For a more detailed explanation about
ventilation requirements, please check the appropriate section within this document.
•Make sure the voltage of the power source (mains) conforms within the permitted range
before connecting the equipment to the power inlet. If you have any doubts, please contact a
licensed electrician to advise you accordingly.
•Place the power cord in such a way that people cannot step on it. Do not place anything over
the power cord.
•ALWAYS shut down the operating system and disconnect the unit from any power sources
before removing any connections (Keyboard, Mouse, etc..) or opening up the unit to fit
additional cards and or devices.
•ALWAYS shut down the operating system and disconnect the unit from any power sources
before removing the front cover or attempting to remove the Blade or the Hard Drive.
•All cautions and warnings on the equipment should be noted and adhered to.
•Never pour any liquid into any openings. This could cause damage or electrical shock.
•If any of the following situations arise, have the equipment checked by qualified service
personnel:
oThe power cord or plug is damaged
oLiquid has penetrated into the DigiPoS Retail Blade™ or the external power supply
oThe equipment has been exposed to moisture
oThe DigiPoS Retail Blade™ is not working well or you can not get it to work according
to the User’s Manual
oThe DigiPoS Retail Blade™ has been dropped and damaged
oThe DigiPoS Retail Blade™ has obvious signs of breakage or physical damage
•Do not leave this DigiPoS Retail Blade™ in a non air-conditioned environment with a storage
temperature above 60ºc (140ºf) as it may damage the equipment.
•For reasons of safety, gloves should be worn when assembling the DigiPoS Retail Blade™
after any work has been carried out.
NOTE
•The technical descriptions, specifications and any associated diagrams or pictures of the
DigiPoS Retail Blade™ are subject to change without notice.
ACHTUNG!
•Wir behalten uns Änderungen der technischen Beschreibungen bzw. Spezifikationen vor.

Ventilation Requirements
Cavity Size
If the Retail Blade™ is to be located in a cavity, i.e. under the counter, the cavity
dimensions must be a minimum of 450mm (17.7”) long by 400mm (15.7”) wide by
200mm (7.9”) deep (excluding the external PSU). A diagrammatic representation is as
follows:
Although this is the required space, the Retail Blade™ MUST be located centrally to
prevent the airflow from being disrupted through the ventilation holes in the sides or the
rear of the case.
Enclosed Spaces
If the Retail Blade™ is to be located in an enclosed space, i.e. in a closed box or cabinet,
there must be sufficient airflow into and out of the enclosed space. Using the above
cavity space, for example, forced airflow would have to be fitted to prevent the Retail
Blade™ from overheating. As a general rule, the Retail Blade™ requires an airflow
exchange rate of a minimum of 25 CFM (Cubic Feet per Minute) excluding PSU or 30
CFM including PSU when in an enclosed space.
The recommended location for these fans is as follows:
Without External PSU With External PSU
Page13 of 100

DigiPoS Retail Blade™Manual
External PSU
DigiPoS Systems recommends that the external PSU for Retail Blade™ is not situated in
the same space as the Retail Blade™ to minimise heat build up in enclosed spaces.
If this is unavoidable, forced air ventilation must be installed or the cavity size increased
to provide adequate ventilation for the Retail Blade™ & PSU heat dissipation devices. A
diagrammatic representation is as follows showing the new cavity size required and the
positioning of the external PSU:
Warning: Failure to observe the minimum ventilation requirements for the Retail
Blade™ will cause the unit to overheat. This will dramatically affect the performance
of the Retail Blade™ and may cause permanent damage which will not be covered
by the warranty.

DigiPoS Retail Blade™Manual
Under Counter Mounting
The Retail Blade™ can be mounted under the counter or on a secure vertical surface to
maximise the available space at the Point of Sale. In order to do this, a special bracket
must be used that has been specifically engineered for the Retail Blade™. This bracket
does not obstruct the ventilation yet still provides a secure mounting without the need
for drilling holes in the case which will void the warranty.
DigiPoS Brackets
To fit the bracket, simply remove the four small black case screws on the side of the
Retail Blade™ and offer up the bracket to the Retail Blade™. Then, using the new longer
screws that came with the bracket, attach the bracket to the Retail Blade™ and secure in
position.
Give due consideration to the mounting of the Retail Blade™ so that the Blade can still
be extracted without having to dismantle to bracket assembly.
The External PSU has mounting holes pre-formed in its case and does not require any
special brackets.
Please contact you’re nearest DigiPoS Systems Office for further details and availability
on these brackets.

The thermal transfer medium between the CPU and the cooling assembly is a
specific type of industrial silicone designed to withstand the more aggressive
environments found within a point of sale installation. We therefore recommend that
only DigiPoS Systems or authorized agents for DigiPoS Systems attempt to remove
the CPU cooling assembly. Failure to comply with this notice shall void all
warranties.
Memory
Each DigiPoS Retail Blade™ can be fitted with two modules of memory. Commonly
referred to as DDR (Double Data Rate) memory, the specifications for this type of
memory is as follows:
Pins 184 Pin Gold
Type SDRAM (Synchronous Dynamic Random Access Memory)
Sizes 256Mb, 512Mb, 1Gb & 2Gb
(Single module or matched Pair)
Clock Speed 266 / 333 / 400Mhz (System FSB x 2)
Using inappropriate types of memory or unmatched pairs of memory may
significantly degrade the performance of your DigiPoS and also void all warranties.
