SAFETY NOTICE: "For pluggable equipment, the socket-outlet shall be installed near the equipment and shall be easily accessible."

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 fieldeffect 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 wriststrap 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.Contents

About the ER-420M

•The ER-420M features a 48-position keyboard with traditional raised keys. This keyboard will accommodate up to 12/16 NLU keys and works best in retail stores, or shops where it is not necessary to place a large number of preset item keys on the keyboard.

•A standard capacity of 1000 PLUs and 20 Groups allows for easy item management. For expansion to 9000 PLUs, please contact your dealer.

•ER-420M is an excellent low cost solution for a wide range of retail environments.

•ER-420M, with its superb thermal printing system, always provides the fastest in transaction speeds.

•ER-420M is preset with GST and Australian rounding as well as a number of other useful functions.

Unpacking

1.Unpack and unwrap the cash register.

2.Located in the packing are the following items:

•2 rolls of paper and 1 paper spindle,

•2 sets of control keys,

•Operation and Program Manual,

3.Remove the cardboard protectors from the cash drawer.

4.Plug the register into a grounded outlet (three prong), insert a control key and turn the key to the REG control lock position.

Installing the Paper

1. Remove the printer cover.

2.For proper feeding through the print head, cut or tear a straight even edge on the end of the paper roll. (Be sure to remove any paper with glue residue.) Place the paper roll in the paper holder so that the paper will feed from the bottom of the roll.

2 • Getting Started

ER420M Electronic Cash Register AU

3. Insert the end of the paper into the paper slot.

4. Close the paper lever and press the PAPER FEED key until the paper comes out.

5.Passing the leading edge of the paper through the cutter slot. Tear off the excess paper. Replace the printer cover.

If you wish to use the printer to print a sales journal, insert the paper into the paper take-up spool. Wind the paper two or three turns around the spool shaft and install the spool in the mount.

ER-420M is possible to feed automatically when you rock the paper levers and insert paper.
