POWER SAVE MODES AND THE MULTI-FUNCTION BUTTON

The MS7220 has five programmable power save modes. Refer to the
MetroSelect Programming Guide for additional information on Power Save
Modes.

1. Blink Power Save Mode (Default):
“Blinks” the laser OFF & ON after a programmed period of non-use.

When the scanner recognizes a bar code it will exit the Blink mode.

2. Laser Off Power Save Mode:
Turns the laser OFF after a programmed period of non-use.

The motor continues to spin allowing for a faster “wake” up time. Pressing
the Multi-Function button will “wake” the scanner from the Laser Off power
save mode (see figure 8d).

3. Laser & Motor Off Power Save Mode:
Turns the laser and motor OFF after a programmed period of non-use.

Pressing the Multi-Function button will “wake” the scanner from the power
save mode (see figure 8d). This mode is the only power save mode that can
be activated by the Multi-Function Button (see figure 8c). This mode’s
“wake up” time is slightly longer due to the motor’s need to restart.

4. Dual Action Power Save Mode #1:
“Blinks” the laser OFF & ON after a programmed period of non-use turns the
laser and motor OFF at thirty-minute intervals.

Example:

If the power save timeout
is set to 15 minutes.

AUDIBLE INDICATORS

When the MS7220 scanner is in operation, it provides audible feedback. These
sounds indicate the status of the scanner. Eight settings are available for the
tone of the beep (normal, 6 alternate tones and no tone). To change the tone,
use the Multi-Function Button or refer to the MetroSelect Programming Guide
(

MLPN 00-02407).

One Beep

When the scanner first receives power, the green LED will turn on,
the red LED will flash and the scanner will beep once. The red LED
will remain on for the duration of the beep. The scanner is now
ready to scan.

When the scanner successfully reads a bar code, the red LED will
flash and the scanner beeps once (if programmed to do so). If the
scanner does not beep once and the red light does not flash, then
the bar code has not been successfully read.

Razzberry Tone

This is a failure indicator. Refer to failure modes page 17.

Three Beeps - during operation

When placing the scanner in program mode, the red LED will flash
while the scanner simultaneously beeps three times. The red and
green LEDs will continue to flash until the unit exits program mode.
Upon exiting program mode, the scanner will beep three times and
the red LED will stop flashing.

16

When configured, 3 beeps can also indicate a communications
timeout during normal scanning mode.

When using one-code-programming, the scanner will beep three
times (the current selected tone), followed by a short pause, a high
tone and a low tone. This tells the user that the single
configuration bar code has successfully configured the scanner.

Three beeps will also occur during a manual adjustment of the
beeper tone. With each short depression of the Multi-Function
Button, the new tone will be heard, followed by a short pause then
two more of the new current tones.

Three Beeps - on power up

This is a failure indicator. Refer to failure modes page 17.

FAILURE MODES

Flashing Green and One Razzberry Tone

This indicates the scanner has experienced a laser subsystem
failure. Return the unit for repair at an authorized service
center.

Flashing Red and Green and Two Razzberry Tones

This indicates the scanner has experienced a motor failure.
Return the unit for repair at an authorized service center.

Continuous Razzberry Tone with both LEDs off

If, upon power up, the scanner emits a continuous razzberry
tone, then the scanner has an electronic failure. Return the
unit for repair at an authorized service center.

Three Beeps - on power up

If the scanner beeps 3 times on power up then, the nonvolatile
memory that holds the scanner configuration has failed.
Return the unit for repair at an authorized service center.

17

VISUAL INDICATORS

There is a red LED and a green LED on the front of the MS7220. When the
scanner is on, the flashing or constant illumination of the LEDs indicates the
status of the current scan and the scanner.

No Red or Green LED

The LEDs will not be illuminated if the scanner is not receiving power
from the host or transformer.

Steady Green

When the laser is active, the green LED is illuminated. The green
LED will remain illuminated until the laser is deactivated.

During the power save mode, the laser will turn on and off. During
this period, the green LED remains illuminated.

Steady Green and Single Red Flash

When the scanner successfully reads a bar code, the red LED will
flash and the scanner will beep once. If the red LED does not flash
or the scanner does not beep once, then the bar code has not been
successfully read.

18

Steady Green and Steady Red

After a successful scan, the scanner transmits the data to the host
device. Some communication modes require that the host inform the
scanner when data is ready to be received. If the host is not ready to
accept the information, the scanner’s red LED will remain on until the
data can be transmitted.

Flashing Green then Flashing Red

This indicates the scanner is in program mode. A razzberry tone
indicates that an invalid bar code has been scanned in this mode.

or

If the unit is in sleep mode, each LED will flash once every 15
seconds.

Steady Red, Green off

This indicates the scanner may be waiting for communication from
the host.

LABELS

Each scanner has a label on the back of the unit. The label contains information
such as the model number, date of manufacture, and the serial number.
Additional CE and caution information has been molded into the back of the
case. The following is an example of the back of the case with the label and

being scanned falls into the
programmed criteria.
(Typical of Non-UPC/EAN
codes. The scanner

defaults to a minimum of 4
character bar code.)

The unit powers
up, but does not
scan and/or

The unit is scanning
a particular
symbology that is not
enabled.

The scanner has
been programmed
for a character length
lock, or a minimum
length and the bar
code being scanned
does not satisfy the
programmed criteria.

The unit scans a
bar code, but
locks up after
the first scan
(the red LED
stays on).

The unit scans,
but the data
transmitted to
the host is
incorrect.

The unit beeps
for some bar
codes and NOT
for others of the
same bar code
symbology.

The scanner is
configured to support
some form of host
handshaking but is
not receiving the
signal.

The scanner’s data
format does not
match the host
system requirements.

The print quality of
the bar code is
suspect.

Check the character
length lock.

The aspect ratio of
the bar code is out of
tolerance.

If the scanner is setup to
support ACK/NAK,
RTS/CTS, XON/XOFF or
D/E, verify that the host
cable and host are
supporting the handshaking
properly.

Verify that the scanner’s
data format matches the
host systems requirements.
Make sure that the scanner
is connected to the proper
host port.

Check the print mode. The
type of printer could be the
problem. Change print
settings. For example
change the print mode to
econo or high speed.

RS232 DEMONSTRATION PROGRAM

If an RS232 scanner is not communicating with your IBM compatible PC,
key in the following BASIC program to test that the communication port
and scanner are working. This program is for demonstration purposes
only. It is only intended to prove that cabling is correct, the com port is
working, and the scanner is working. If the bar code data displays on the
screen while using this program, it only demonstrates that the hardware
interface and scanner are working. At this point, investigate whether the
application software and the scanner configuration match. If the
application does not support RS-232 scanners, a software wedge
program that will take RS-232 data and place it into a keyboard buffer
may be needed. This program tells the PC to ignore RTS-CTS, Data Set
Ready (DSR) and Data Carrier Detect (DCD) signals. If the
demonstration program works and yours still does not, jumper RTS to
CTS and Data Terminal Reading (DTR) to DCD and DSR on the back of
your PC.

LASER AND PRODUCT SAFETY

Caution

Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous laser light exposure. Under no
circumstances should the customer attempt to service the laser scanner. Never
attempt to look at the laser beam, even if the scanner appears to be
nonfunctional. Never open the scanner in an attempt to look into the device.
Doing so could result in hazardous laser light exposure. The use of optical
instruments with the laser equipment will increase eye hazard.

Atención

La modificación de los procedimientos, o la utilización de controles o ajustes
distintos de los especificados aquí, pueden provocar una luz de láser peligrosa.
Bajo ninguna circunstancia el usuario deberá realizar el mantenimiento del láser
del escáner. Ni intentar mirar al haz del láser incluso cuando este no esté
operativo. Tampoco deberá abrir el escáner para examinar el aparato. El
hacerlo puede conllevar una exposición peligrosa a la luz de láser. El uso de
instrumentos ópticos con el equipo láser puede incrementar el riesgo para la
vista.

Attention

L'emploi de commandes, réglages ou procédés autres que ceux décrits ici peut
entraîner de graves irradiations. Le client ne doit en aucun cas essayer
d'entretenir lui-même le scanner ou le laser. Ne regardez jamais directement le
rayon laser, même si vous croyez que le scanner est inactif. N'ouvrez jamais le
scanner pour regarder dans l'appareil. Ce faisant, vous vous exposez à une
rayonnement laser qú êst hazardous. L'emploi d'appareils optiques avec cet
équipement laser augmente le risque d'endommagement de la vision.

Achtung

Die Verwendung anderer als der hier beschriebenen Steuerungen, Einstellungen
oder Verfahren kann eine gefährliche Laserstrahlung hervorrufen. Der Kunde
sollte unter keinen Umständen versuchen, den Laser-Scanner selbst zu warten.
Sehen Sie niemals in den Laserstrahl, selbst wenn Sie glauben, daß der
Scanner nicht aktiv ist. Öffnen Sie niemals den Scanner, um in das Gerät
hineinzusehen. Wenn Sie dies tun, können Sie sich einer gefährlichen
Laserstrahlung aussetzen. Der Einsatz optischer Geräte mit dieser
Laserausrüstung erhöht das Risiko einer Sehschädigung.

Attenzione

L’utilizzo di sistemi di controllo, di regolazioni o di procedimenti diversi da
quelli descritti nel presente Manuale può provocare delle esposizioni a raggi
laser rischiose. Il cliente non deve assolutamente tentare di riparare egli
stesso lo scanner laser. Non guardate mai il raggio laser, anche se credete
che lo scanner non sia attivo. Non aprite mai lo scanner per guardare dentro
l’apparecchio. Facendolo potete esporVi ad una esposizione laser rischiosa.
L’uso di apparecchi ottici, equipaggiati con raggi laser, aumenta il rischio di
danni alla vista.
