Safety

The Dolphin 7400 handheld computer meets or exceeds the requirements of all applicable standards organizations for safe operation. However, as with any electrical equipment, the best way to ensure safe operation is to know the possible risks.

The following safety guidelines are designed to protect both you and others around you. Please read them carefully before using your Dolphin terminal.

Required Safety Labels

Batch Terminals

The following is the the required safety label as it appears on the back panel of the Dolphin 7400 batch terminal:

If Your Dolphin 7400 has a radio

The Dolphin® 7400 RF terminal is designed to comply with the most current applicable standards on safe levels of RF energy developed by the Institute of Electrical and Electronics Engineers (IEEE) and the American National Standards Institute (ANSI) and has been recommended for adoption by the Federal Communications Commission (FCC).

•

The following is the the required safety label as it appears on the back panel of the Dolphin 7400 RF terminal:

FCC Compliance

The Dolphin 7400 Batch and RF terminals both comply with part 15 of the FCC rules. Operation is subject to the following two conditions:

1. Devices may not cause harmful interference.

2. Devices must accept any interference received, including interference that may cause undesired operation.

For further information please contact, Hand Held Products (UK) Ltd.

st Floor

Dallam Court Dallam Lane Warrington, Cheshire WA2 7LT England

Hand Held Products shall not be liable for use of our product with equipment (i.e.,power supplies, personal computers, etc.) that is not CE marked and does not comply with the Low Voltage Directive.

Pacemakers, Hearing Aids and Other Electrically Powered Devices

Most manufacturers of medical devices adhere to the IEC 601-1-2 standard. This standard requires devices to operate properly in an EM Field with a strength of 3V/m over a frequency range of 26 to 1000MHz.

The maximum allowable field strength emitted by the Dolphin is 0.3V/m according to Subpart B of Part 1 of the FCC rules. Therefore, the Dolphin RF will have no effect on medical devices that meet the IEC specification.

Microwaves

The radio in the Dolphin RF terminal operates on the same frequency band as a microwave oven. Therefore, if you use a microwave within range of the Dolphin RF terminal you may notice performance degradation in your wireless network. However, both your microwave and your wireless network will continue to function.

•

Batteries

The Dolphin Batch terminal does not contain a radio, and therefore, is not affected by microwave ovens.

The following are general guidelines for the safe use and disposal of batteries:

•

Use only the battery supplied with your Dolphin or a replacement battery supplied, recommended, or approved by Hand Held Products, Inc.

•

Replace a defective battery immediately as it could damage the Dolphin terminal.

•

Never thr ow a used battery in the tr ash. It contains hea vy metals and should be recycled according to local guidelines.

•

Don’t short-circuit a battery or throw it into a fire. It can explode and cause severe personal injury.

•

Excessive discharge damages a battery. Recharge the battery when your Dolphin indicates low battery power.

•

Although your battery can be recharged many times, it will eventually be depleted. Replace it after the recommended usage period (about 600 charge cycles for the 2700 mAh NiMH battery) or if the battery is unable to hold an adequate charge.

•

If you are not sure the battery or charger is working properly, please send it to Hand Hand Products or an authorized Hand Held Products service center, for inspection.

The Dolphin handheld computer meets or exceeds all applicable standards and has been manufactured to the highest level of qual ity.

Care and Cleaning of the Dolphin

When needed, clean the image engine window and the LCD display with a clean non-abrasive, lint-fr ee cloth.

•

Using Dolphin 7400 for the First Time

Follow these steps to begin using your Dolphin 7400 terminal.

1. Unpack and check the terminal and documentation.

2. Charge the main battery pack and internal back-up battery.

3. Turn the Dolphin on.

4. Calibrate the screen, set the date/time, and user information.

5. Verify that your Dolphin 7400 terminal is working properly.

1 Unpack the Carton and Check Its Contents

Inspect the package to see that the following standard items and accessories (if ordered) are included in the standard Dolphin 7400 kit:

•

Dolphin 7400 handheld computer/bar code scanner

•

Battery (2700 mAh, Nickel Metal Hydride [NiMH])

•

Dolphin 7400 HomeBase

RS-232 Serial Cable

•

AC-DC Power Adapter for Dolphin Terminal/HomeBase

•

Dolphin 7400 Software Development Kit & User’s Guide CD-ROM

Note: Be sure to keep the original packaging in the event that the Dolphin terminal or

HomeBase should need to be returned for service.

2 Charging the Main Battery and Backup Battery

WARNING

use of any other battery pack in the Do lph in terminal wi ll void your warranty an d may result in damage to the Dolphin terminal or battery.

The terminal’s NiMH battery is shipped discharged of all power so you must charge it before using it for the first time. To charge the main battery pack:

1. Place the main battery pack in the Dolphin 7400 terminal.

2. Place the terminal in the terminal well of the Dolphin HomeBase™. Time to Charge: 3.5 hours for the main battery; 8 hours for the back-up battery

As the main battery pack charges, the internal back-up battery also charges. For the initial charging cycle, it is recommended that the terminal be charged for approximately 8 hours to allow adequate charging time for the back-up battery. Not doing so may result in the terminal becoming unstable should the unit lose power and the back-up battery is required. The back-up battery maintains the RAM and clock when the NiMH main battery pack is discharged or removed from the terminal.

For maximum battery life, you must service, or deep cycle, the main battery pack twice before initial use. It is also recommended that you service the battery once per month. Refer to the section on Battery Management in Chapter 3 for further information.
