Installation

The MS350 Wireless Imager is easy to install and use.

Please see the following figure showing the steps to perform

the installation.

* Note: Turn off the host computer before installation.

1. Connect the interface (I/F) cable to the cradle.

2. Connect the power cord to the cradle.

3. Route the I/F cable and power cord through the notch.

4. Connect the I/F cable to the host computer

communication port.

5. Connect the AC adapter to the wall outlet.

6. Place the imager in the cradle and verify the charge

LED is flashing. Charge the battery for at least 8 hours

before the first use.

7. To verify operation, please link the imager with cradle

first (Refer to “Wireless Connection” in page 5). Point

the imager at the barcode and pull the trigger. The

imager should emit a beep indicating that the barcode

has been scanned and transmitted to the cradle

successfully.

How To Scan

1. The imager must be pointed at slight angle to the

barcode so that the light reflected off the barcode can

be seen by the imager. Do not hold the imager

perpendicular to the barcode.

2. The scan line must cross the entire barcode. The

imager can not read the barcode data without seeing

the entire barcode.

Troubleshooting

If the imager can not operate properly, the following checks

should be performed:

1. The cradle uses an external power supply and the

external power supply has failed, the imager will not

operate. Change the power supply with a known good

power supply and reset the imager.

2. Verify the interface cable is securely connected to the

host computer. Consult your technical support

personnel or refer to your host system manual to verify

the proper connection for the imager.

3. Verify the interface cable is securely connected to the

cradle.

4. Check that the barcodes are of sufficient quality to be

recognized by the imager. Wrinkled, smudged, or torn

labels will cause the imager to not read at all. Scan a

known good label to check the imager’s read operation.

5. Ensure that the cradle’s interface type is compatible

with the host computer by consulting your host system

manual.

Wireless Connection

Linking the imager with the cradle

Follow these instructions to link the two devices:

1. Connect power to the cradle. The radio LED (marked

with a light symbol) will blink amber and the cradle will

beep.

2. To ensure the cradle is unlinked from any other imager,

check if the cradle send inquiry beep or not (see Inquiry

Beep Control in page 18).

3. Read the link label on the bottom of the cradle with the

imager. The imager will sound a good read beep and

the LED will flash amber.

4. Re-place the imager in the cradle to continue the

charge.

Once an imager is linked to a cradle, they will remain linked

until specific action is taken to unlink them (see Unlinking).

They will remain linked if the cradle is unplugged, if the

battery is removed from the imager or if the entire charge is

used up, and if the imager is taken out of range of the cradle.

Under normal operation, scanning of the link label will only be

required once in the life of the product.

Unlinking

There are three ways to unlink an imager from a cradle:

Force imager to disconnect and sleep

1. Scan the “Force imager to disconnect and sleep”

barcode – Reading the unlink barcode above while the

imager is in range of the cradle will break the link

between the two devices and allow another imager to

link to the cradle. It will also have the imager in Deep

Sleep Mode. If the barcode is read when the imager is

out of range of its linked cradle, the imager will unlink,

but the cradle will remain linked to the imager and will

not allow another imager to be linked to it. In this case,

you may perform the item 2 below to link another

imager.

2. Scan the Link Label and put on the original cradle –

If the cradle is linked with an imager and the original pair

was stopped by out of range of the cradle or out of

battery of the imager, scan the link label of the cradle

with a new imager and then put on the cradle, the cradle

will drop the original pair and establish a new link with

the new imager.

3. Scan the Link Label on an alternate cradle –

Scanning the link label on a cradle will drop the link

between the original pair and establish a link between

the imager and new cradle. If the new link is performed

within range of the old cradle, it is free to establish a link

to the next imager that reads its link label. If it is done

outside of the range of the old cradle, it retains its old

link and will not allow a new imager to link to it until a

new imager scan the link label and put on the cradle.

4. Push the “Reset” button on the bottom of cradle – If

the cradle is linked with an imager and in range,

pushing the “Reset” button (for about 2 seconds) on the

bottom of cradle will drop the link between the devices.

If the button is pushed while the imager is out of range,

the cradle will unlink and make itself available to other

imagers. The scanner will not drop its link with the

cradle automatically, but can be linked to any other

cradle by reading its link label.

* Note: If just push the button with a short time (less than one

second), a “Paging” feature will be performed to page the

imager which was linked with the cradle.

Battery Charging

The imager contains a 1000mAh Lithium-Ion rechargeable

battery. A full charged battery will provide up to 15,000 scans

over a 12 hours period. Actual charge life on the imager will

depend on the configuration of how the imager is configured

via the programmable feature in this manual; in particular,

Deep Sleep Mode settings can impact battery life.

When the imager is placed in the cradle, the battery will

automatically charge. While charging is taking place, the

charging LED (marked with a battery symbol) will blink green.

When the battery is fully charged, the charging LED will stay

on a solid green.

If there is an error in charging either with a failure in the

charging circuit or with a failure of the battery, the charging

LED will flash red. When this happens, the battery needs to

be replaced.

How to Change the Battery

In case the contained battery inside the imager needs to be

replaced, please follow the procedures below:

1. Loosen the screw at the

bottom of the imager.

2. Take off the battery cover

out of the imager.

5. Use a new battery pack

and replace the used one.

3. Disconnect the battery

cable connector from the

main board.

4. Remove the used battery

from the battery container.

Note: DO NOT touch the PCBA inside the imager when

replacing the battery. Improper operation may damage the

imager.

6. Place the new battery into

the battery container.

7. Connect the battery cable

connector to the main board.

8. Put the battery cover back

to the imager handle.

9. Fasten the screw to the

imager.
