Built to last, the Dolphin's ruggedly built case houses a 386 microprocessor and DOS operating system that is easily programmable with standard programming tools like Microsoft Visual C/C++, Borland C/C++, or Visual Basic.

Durability

Dolphin is one of the most durable devices available, and is designed to withstand repeated five-foot drops onto a concrete floor. It also resists extreme temperatures, humidity levels and dust conditions.

Features

The Dolphin's basic features include long-lasting Nickel Metal Hydride (NiMH) batteries, a large, easy-to-read 8 line x 20 character backlit display that can display text or graphics, a natural scan and viewing angle, and two keypad options.

Multiple Configurations

The multiple configurations available for the Dolphin 7200 make it one of the most versatile terminals in the automatic data collection industry. The terminal may be equipped with a scan engine capable of reading all standard bar code symbologies.

terminal. Therefore, you will see a DOS prompt on the screen; for example:

Dolphin® 7200 User’s Guide 2 - 5

C:\ or A:\ .

Note: If using the Dolphin for first time or if the terminal has been without a battery pack for more than 30 minutes and you are

now inserting a battery, you may receive a CMOS error when the terminal boots up. Don't worry, the terminal is OK. This simply means that the internal back-up battery needs to be recharged and the date and time need to be reset. To recharge the internal backup battery and reset the date and time, insert a fully charged battery in the Dolphin and then use the DOS date and time function to set the correct date and time. The internal back-up battery requires a minimum of 5 hours of charging time in order to perform and maintain the system as described on page 30.

Turning the Dolphin Off

The Dolphin is never actually turned off. To conserve power, the Dolphin goes into "sleep mode" when it is inactive for a programmed period of time as defined by your application. The screen is blank when the Dolphin is in "sleep mode."

Step 4. Setting the Date and Time

Use the DOS date and time function to set the correct date and time for your Dolphin terminal.

To Set the Date on an Alphanumeric Terminal:

1. Enter DATE at the Dolphin's DOS prompt.

2. Press NUM LOCK to put the Dolphin in numeric mode.

3. Enter the new date mm-dd-yyyy.

4. Press ENTER.

To Set the Date on a Numeric Terminal:

1. Press SHIFT to put the Dolphin in alpha mode.

2. Enter DATE at the Dolphin's DOS prompt; see Using the Numeric Keypad on page 3-4.

3. Press SHIFT to put the Dolphin back in numeric mode.

4. Enter the new date mm-dd-yy.

5. Press ENTER.

To Set the Time

To enter the new time, enter TIME at the Dolphin's DOS prompt instead of DATE and follow the directions for the Dolphin model you are using.

Maintaining the Dolphin's Batteries

Although the Dolphin 7200 terminal is received with the battery inserted, it is NOT ready for charging and/or deepcycling. Remove the plastic insulator located between the terminal and battery connectors. Failure to remove the insulator may result in damages to the terminal.Use only the 3.6V battery packs provided by Hand Held Products. The

use of any other battery pack in the Dolphin 7200 terminal will void your warranty and may result in damage to the Dolphin terminal or battery.

There are two batteries in the Dolphin:

1. Internal NiMH Backup Battery - Located inside the Dolphin, this battery backs up the RAM and clock when the NiMH main

battery is discharged or removed from the terminal.

2. NiMH Battery Pack - Inserted into the back panel, the battery pack is the primary power source for operating the Dolphin.

Internal NiMH Backup Battery

The Dolphin's internal backup battery prevents the terminal from being reset if you need to remove and replace the main battery pack. The battery retains RAM data and allows the real-time clock to remain operational for up to 30 minutes when the battery pack is removed. If the internal back-up battery becomes discharged of power, it requires a minimum of 5 hours of charging time in order to perform and maintain the system as described above.

The internal backup battery is charged by the Dolphin's main battery pack. If the terminal is left without the main battery pack for more than 30 minutes, the internal backup battery needs to be recharged.

Note: Data and programs on Drives C and D remain safe even if the internal backup battery fails. However, you must reset the

real-time clock using the DOS Time and Date function.

Guidelines

Follow these guidelines to maximize the life of the Dolphin's backup battery:

• Keep a charged NiMH battery pack in the Dolphin. The internal battery will prematurely discharge if there is not at least a partially charged battery in the terminal.

• Put the Dolphin in the HomeBase when the terminal is not in use.

Note: Return the Dolphin to an authorized service center when the internal battery needs to be replaced.

NiMH Battery Pack

The 3.6V, 1500 mAh Nickel-Metal-Hydride (NiMH) battery pack is the primary power source for the Dolphin. Other Nickel-MetalHydride batteries may be approved by Hand Held Products, Inc. to work with your Dolphin. Contact Hand Held for more information.

The 1500 mAh NiMH battery is designed to operate in temperature range of -10 to 50 C (14 to 122 F). For maximum performance, charge the batteries between 10 and 35 C (50 and 95 F).

insulator may result in damages to the terminal

Performance specifications for a fully charged 1500 mAh NiMH battery (using power management function calls within application):

• Up to 20 hours of usage in a Dolphin Batch terminal with a full battery charge

• Up to 20 hours of usage in a Dolphin 2D terminal with a full battery charge

Keep a charged battery pack in the Dolphin at all times to conserve the internal back-up battery. When you remove a battery pack, insert another battery pack in the Dolphin. The internal battery will prematurely discharge if there is not at least a partially charged battery in the terminal.

3 - 8 Dolphin® 7200 User’s Guide

Servicing the Battery Pack

For maximum battery life, Hand Held Products recommends that you deep-cycle the battery twice before initial use. To deep cycle, insert the battery into the HomeBase auxiliary battery well. Then, push and hold the Service Aux Batt button for at least 4 seconds. For more information, see Charging an Additional NiMH Battery Pack on page 8-6.

You may also deep cycle the battery using the CycleBat battery utility conditioning software which is available from the Partners area of the Hand Held Products web site www.handheld.com. More information on this utility is available from the help file that comes with the software.

Note: For maximum battery life, Hand Held Products recommends that you deep-cycle (service) the battery twice before initial

use and then, once a month thereafter.

Hand Held Products also recommends that you service, or calibrate the battery once per month. For details, see Servicing the

Battery Pack on page 11-3.

Charging the Battery Pack

You can recharge an individual battery pack using the auxiliary battery well of the Dolphin HomeBase, or the Dolphin 10-Slot MultiCharger.

Note: Keep a charged battery pack in the Dolphin at all times to conserve the internal back-up battery.

For details about the Dolphin HomeBase, see Charging Batteries in the Dolphin 7200 HomeBase on page 8-5. For details about the Dolphin MultiCharger, see Charging Batteries in the Dolphin MultiCharger on page 11-3.

Storing Battery Packs

To maintain top performance from batteries, follow the guidelines below when storing them:

• Avoid storing batteries outside of the specified range of -4 to 104° F (-20 to 40°C) or in extremely high humidity.

• For prolonged storage, do not keep batteries stored in the terminal.

• During long-term storage, battery deactivation may tend to occur which may cause charging to stop early during recharging after storage. Charging and discharging the battery several times can handle this issue. Also, the first charging after prolonged storage may yield a lower than normal capacity. While this will vary depending on the storage conditions, charging and discharging the battery several times will almost completely restore capacity.
