Precaution Statements
Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as
electrical shock.
1-1 Safety Precautions
1. Be sure that all built-in protective devices are
replaced. Restore any missing protective shields.
2. When reinstalling the chassis and its assemblies,
be sure to restore all protective devices, including
nonmetallic control knobs and compartment
covers.
3. Make sure there are no cabinet openings through
which people - particularly children - might insert
fingers and contact dangerous voltages. Such
openings include excessively wide cabinet
ventilation slots and improperly fitted covers and
drawers.
4. Design Alteration Warning:
Never alter or add to the mechanical or electrical
design of the SECR. Unauthorized alterations
might create a safety hazard. Also, any design
changes or additions will void the manufacturer’s
warranty.
5. Components, parts and wiring that appear to have
overheated or that are otherwise damaged should
be replaced with parts that meet the original
specifications. Always determine the cause of
damage or over- heating, and correct any potential
hazards.
6. Do not remove original insulation, especially near
the following areas: sharp edges, and especially
the AC and high voltage supplies. Always inspect
for pinched, out-of-place, or frayed wiring. Do not
change the spacing between components and the
printed circuit board. Check the AC power cord
for damage. Make sure that leads and components
do not touch thermally hot parts.
7. Product Safety Notice:
Some electrical and mechanical parts have special
safety-related characteristics that might not be
obvious from visual inspection. These safety
features and the protection they give might be lost
if the replacement component differs from the
original - even if the replacement is rated for
higher voltage, wattage, etc.
Components that are critical for safety are
indicated in the circuit diagram by shading, ( )
or ( ). Use replacement components that have
the same ratings, especially for flame resistance
and dielectric strength specifications. A
replacement part that does not have the same
safety characteristics as the original might create
shock, fire or other hazards.
CAUTION
There is the danger of explosion if battery is incorrectly
replaced.
Replace only with the same or equivalent type
recommended by the manufacturer.
Dispose used batteries according to the manufacturer’s
instructions.
ATTENTION
ll y a danger d’explosion s’il y a remplacement incorrect
de la batterie.
Remplacer uniquement avec une batterie du même type
ou d’un type équivalent recommandé par le constructeur.
Mettre au rebut les batteries usagées conformément aux
instructions du fabricant.
SAFETY NOTICE: "Electrical equipment should be installed near an easily accessible socket/outlet."

1-2 Servicing Precautions
WARNING: First read the-Safety Precautions-section of this manual. If some unforeseen circumstance creates a
conflict between the servicing and safety precautions, always follow the safety precautions.
WARNING: An electrolytic capacitor installed with the wrong polarity might explode.
1. Servicing precautions are printed on the cabinet.
Follow them.
2. Always unplug the units AC power cord from the
AC power source before attempting to:
(a) Remove or reinstall any component or assembly
(b) Disconnect an electrical plug or connector
(c) Connect a test component in parallel with an
electrolytic capacitor
3. Some components are raised above the printed
circuit board for safety. An insulation tube or tape
is sometimes used. The internal wiring is
sometimes clamped to prevent contact with
thermally hot components. Reinstall all such
elements to their original position.
4. After servicing, always check that the screws,
components and wiring have been correctly
reinstalled. Make sure that the portion around the
serviced part has not been damaged.
5. Check the insulation between the blades of the AC
plug and accessible conductive parts (examples:
metal panels and input terminals).
6. Insulation Checking Procedure: Disconnect the
power cord from the AC source and turn the power
switch ON. Connect an insulation resistance meter
(500V) to the blades of AC plug.
The insulation resistance between each blade of the
AC plug and accessible conductive parts (see
above) should be greater than 1 megohm.
7. Never defeat any of the B+ voltage interlocks.
Do not apply AC power to the unit (or any of its
assemblies) unless all solid-state heat sinks are
correctly installed.
8. Always connect an instrument’s ground lead to the
instrument chassis ground before connecting the
positive lead; always remove the instrument’s
ground lead last.
1-3 Precautions for Electrostatic Sensitive Devices (ESDs)
1. Some semiconductor (solid state) devices are easily
damaged by static electricity. Such components are
called Electrostatic Sensitive Devices (ESDs);
examples include integrated circuits and some field-
effect transistors. The following techniques will
reduce the occurrence of component damage caused
by static electricity.
2. Immediately before handling any semiconductor
components or assemblies, drain the electrostatic
charge from your body by touching a known earth
ground. Alternatively, wear a discharging wrist-
strap device. (Be sure to remove it prior to applying
power - this is an electric shock precaution.)
3. After removing an ESD-equipped assembly, place
it on a conductive surface such as aluminum foil to
prevent accumulation of electrostatic charge.
4. Do not use Freon-propelled chemicals. These can
generate electrical charges that damage ESDs.
5. Use only a grounded-tip soldering iron when
soldering or unsoldering ESDs.
6. Use only an anti-static solder removal device.
Many solder removal devices are not rated as anti-
static; these can accumulate sufficient electrical
charge to damage ESDs.
7. Do not remove a replacement ESD from its
protective package until you are ready to install it.
Most replacement ESDs are packaged with leads
that are electrically shorted together by conductive
foam, aluminum foil or other conductive materials.
8. Immediately before removing the protective
material from the leads of a replacement ESD,
touch the protective material to the chassis or
circuit assembly into which the device will be
installed.
9. Minimize body motions when handling unpackaged
replacement ESDs. Motions such as brushing
clothes together, or lifting a foot from a carpeted
floor can generate enough static electricity to
damage an ESD.

1-4 Safe Operation
Do not locate your SAM4s ECR in a damp or wet environment. Avoid high humidity, direct
sunlight and temperature extremes.
Always plug your ECR into a grounded three-prong outlet. Never use two-prong adaptors or
ungrounded outlets.
Check to make sure the power outlet provides the correct voltage: (120V +/- 10%).
Immediately disconnect the ECR from the power source in case of spilled liquid in the ECR,
smoke, or strange smells. Call your authorized dealer for assistance.
Do not operate the ECR with wet hands.
Use a soft dry cloth to clean the ECR cabinet. Do not use wet clothes or solvents.
Do not open the ECR case to attempt repairs. Dangerous voltages can cause shock. Service
attempts by untrained personnel can cause unnecessary damage to your ECR.
1-5 Power Requirements
Be aware that other electrical devices on the same circuit can cause your ECR to malfunction. Avoid
plugging your ECR into outlets where other high-current devices are connected.
Be aware that power quality issues, including voltage fluctuations, electrical noise, spikes, outages,
interruptions, and other power viruses can disrupt or damage modern electronic equipment, including
ECRs and PCs.
1-6 Surge Protectors and Power Conditioners
Most people are familiar with surge protectors, which guard against damage due to sudden spikes in
the electrical current. A power conditioner provides protection against surges in power just as a surge
suppressor does, but a power conditioner also maintains a continuous voltage during temporary
voltage reductions, such as a brownout. This is referred to as conditioning. Power conditioners also
can filter EMI emanating from a power source and can smooth the rhythmic cycle of alternating
current. While surge protectors safeguard equipment, a power conditioner cleans the signal,
eliminating interference on the line.
CRS recommends the PowerVAR ABC065-11 (CRS P/N 701002), a 0.65 amp power
conditioner that is suitable for most ECR applications. POWERVAR standard power
conditioners are for use with any microprocessor based electronic equipment.

Quick Start Guide
About the SAM4s ER-285M
The SAM4s ER-285M electronic cash register features a flat spill-resistant 49-position
keyboard with 15 category keys. Because this model has a flat keyboard, you can quickly
and easily setup or change key labels by printing or typing on the key sheet that lays under
the protective overlay. This configuration is ideal for a wide range of food service
environments or retail environments where the possibility of spills may be an issue. With its
superb thermal printing system, the ER-285M provides extremely fast and quiet operation.
Ready to Use
Each SAM4s ECR is ready to use after un-boxing and loading the paper.
The standard keyboard contains all the functions you will need for basic cash register
operation.
A standard capacity of 15 category keys, 2000 PLUs and 20 Groups allows for easy
item management.
In areas where sales tax is charged, you will want to enter the tax rate and set the
taxable status for each category key.
You will also wish to set descriptors for categories; if you choose not to set
descriptors, the default descriptors “PLU1, PLU2,” etc. will be used.
Carefully read and follow the steps in this chapter to complete these basic programming steps
and put your SAM4s ER-285M into service.
Easy to Customize
This manual also contains instructions for higher-level options and features that are available
for the ER-285M. Among many options, you can add or relocate function keys on the
keyboard, or you can connect POS peripherals including a DataTran integrated payment
appliance. The programs required for these options are fully explained in the reference
sections of this manual. You may require the assistance of your professional cash register
dealer to design and implement your special requirements or options.
