Checking Battery Power - Honeywell 7600BG-122-B4EE - Hand Held Products Dolphin 7600 User Manual

Internal Backup Battery
Located inside the terminal, the backup battery is a 2.4V nickel metal hydride (NiMH) battery.
The internal backup battery prevents the terminal from being reset when you remove the main battery
pack. This battery retains RAM data and allows the real-time clock to remain operational for up to 30
minutes. If the terminal is left without the main battery pack for more than 30 minutes, the internal backup
battery discharges and needs to be recharged to function according to specifications.
Note: Even if the internal backup battery fails, data and programs stored in Flash memory (IPSM) or an optional
SD card are not lost. However, the terminal automatically cold boots when you install a fully charged battery
pack and you need to reset the real-time clock.
Charging
The internal backup battery charges off the main battery pack and requires eight hours charge time to
backup RAM data for 30 minutes. You can begin using the Dolphin terminal after charging the main
battery for four hours; however, the internal backup battery will continue to charge off the main battery.
To ensure that the internal backup battery functions properly, maintain a consistent power supply for the
first eight hours of terminal operation. This power supply can be external power (using a charging
peripheral) or an installed, charged battery pack or a combination of both.
Guidelines
Follow these guidelines to maximize the life of the Dolphin's internal backup battery:
• Keep a charged Li-ion battery pack in the Dolphin terminal.
• Keep the Dolphin terminal connected to a power source when the terminal is not in use.
