Preface

PS705 is a high performance, multi-interface, and omni-directional scanner.
The unit comes with powerful reading sensitivity which allows hands-free bar
code scanning. Bar code labels are read by presenting the label towards the
scanner. Scanning labels with PS705 hardly requires any arm movement.

PS705 reads all popular bar code symbologies. An important feature of PS705
is its auto-sense mode. If the scanner is not used within a programmable
period of time, the scanner switches off automatically. The scanner can be
reactivated by placing a barcode towards the window of the PS705.

PS705 is designed with a specific size for all kinds of store applications and
ideal to use in check out services.

1.1 LASER SAFETY

English:

PS705 scanner complies with safety standard IEC60825-1 (2001) for a Class I
laser product. It also complies with U.S. 21CFR1040 as applicable to a Class
IIa laser product. Avoid long term viewing of direct laser light.

Optical:

The use of optical instruments with this product will increase eye hazard.
Optical instruments include binoculars, microscopes and magnifying glasses
but do not include eye glasses worn by the user.

Radiant Energy:

PS705 uses a low-power laser diode operating at 650 nm in an opto­mechanical scanner resulting in less than 0.6 mW peak output power. Laser
light observed at 13 cm (5.1 in.) above the window through a 7 mm (0.28 in.)
aperture and averaged over 1000 seconds is less than 3.9 µW per CDRH
Class IIa specification. Do not attempt to remove the protective housing of the
scanner, as unscanned laser light with a peak output up to 0.8 mW could be
accessible inside.

Laser Light Viewer:

The scanner window is the only aperture through which laser light may be
observed on this product. A failure of the scanner motor, while the laser diode
continues to emit a laser beam, may cause emission levels to exceed those for
safe operation. The scanner has safeguards to prevent this occurrence. If,
however, a stationary laser beam is emitted, the failing scanner should be
disconnected from its power source immediately.

Adjustments:

Do not attempt any adjustments to or alteration of this product. Do not remove
the scanner’s protective housing. There are no user-serviceable parts inside.

WARNING!

Use of controls or adjustments or performance of
procedures other than those specified herein may result in
hazardous laser light exposure.

C. TROUBLESHOOTING

This section contains information on solving problems you may encounter
when using the scanner. If troubles occur, take a moment to read the
information in this section. However, before referring to the diagnostic tips
ensure that the scanner is installed as described in Chapter 2 and that all
cables are properly connected.

Problem Diagnostic Tips

The scanner is on but a barcode
cannot be read.



The scanner window is dirty. Clean

the scanner window as described in
section 3.3.

 The presented barcode type is not

enabled. Select the barcode type with
the Configuration Guide.

 The scanner is disabled by the host.

Refer to section 3.2.

 The barcode type you presented to

the scanner is not supported by
PS705.

The scanner does not accept more
than two or three barcodes.



There is no proper handshaking with

the host system. Switch the host
system on and check connection and
communication settings.

A barcode is read by the scanner
but not accepted by the host
system.



The communication cable is not

connected to the serial port of your
host system. Refer to the manual of
your host system to locate the serial
port.

 The communication settings of the

host and scanner do not match.
Ensure that the setting values for both
devices are the same. For proper
adjustment values, refer to the
Configuration Guide.

 The communication cable does not

suit your host system. Contact your
supplier for the correct communication
cable.

Appendices

26



The data format is not supported by

the software running on the host
system.

USB communication is not
working.



In case of KB emulation you can

select various ‘keyboard languages’
or the universal ‘Alt-input-method’
(default). You may want to try
programming barcodes from section

3.4 on the Configuration Guide.

 In case of KB emulation in

combination with the Alt-input method,
check that Num-Lock of your
keyboard is on.

 In MS-windows environment, verify

with the device manager that the HID
(Human Interface Device) is installed
for the scanner.

 Check that the scanner and the host

system both expect the same USB
protocol (KB emulation, RS232
emulation or IBM POS protocol). See
the Configuration Guide for setup
codes and reset the scanner after
making any changes. When using a
standard-USB cable, the scanner
defaults to the USB KB emulation
protocol with ALT-method character
transmission. When using USB plus
power cable (with the green
connector), the scanner defaults to
USB-IBM-POS protocol for tabletop
scanners. These settings are restored
after programming “back to default”
using the Configuration Guide.

Due to Unitech’s continuing product improvement programs, specifications and features are subject to change without

notice.
