Troubleshooting
Dolphin Terminal and HomeBase
This table describes some of the common problems/symptoms and solutions that you could encounter while using your Dolphin
terminal or Dolphin HomeBase. If you need further assistance with troubleshooting your terminal, contact your Hand Held
Products Authorized Reseller.
Troubleshooting the Dolphin Terminal and HomeBase
If You Have This Problem/Symptom Try This:
The display is blank, the Dolphin
terminal will not turn on. Is the battery is low? Recharge or replace it with a known good battery. Reset
the Dolphin terminal.
When booting up the Dolphin, I see
the message
CMOS MEM size
wrong for a second or two and the
unit continues to boot. Is there
something wrong with my unit?
When the Dolphin's internal NiMH battery is not charged or run down, this
message will display and the terminal's settings are reset to their default
values. This includes the date and time which is reset to January 1, 1980 and
12:00 AM. The terminal is fine. You simply need to recharge the internal
battery and reset the Dolphin's date and time. To do this, 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. For
more information about battery maintenance,
Maintaining the Dolphin's
Batteries (page 3-8).
The Dolphin terminal will not scan a
bar code. The bar code may be out of spec. Try reading some of the bar code examples
in Appendix C, or locate a bar code sample that you know can be read by
another Dolphin terminal.
Is the exit window dirty? Clean it with a soft dry cloth. If the exit window is
badly scratched, the Dolphin terminal should be returned to Hand Held
Products for repair.
Consult your software developer to ensure the correct bar code symbology is
being used.
The battery in the Dolphin terminal
keeps failing. If the battery has been stored for a long period of time, it may take three
charge/discharge cycles before the battery reaches its full storage capacity.
The capacity of NiMH batteries decreases as the number of charge/discharge
cycles increases. So, if you are experiencing low run times, a new battery may
be required.
To increase the run time of the Dolphin terminal, try to limit the use of the
speaker, scan engine and backlight.
The Dolphin terminal is not
communicating with the host
computer. Make sure the HomeBase is connected to a power source.
Make sure the Dolphin terminal is inserted properly into the HomeBase. The
CHARGING MAINBATT LED should be solid green. If not, remove the
Dolphin terminal and reinsert it into the HomeBase.
Ensure the communications baud rate is set correctly. Set communications for
57600, N, 8, 1. Make sure that Configuration Switch 2 on the back of the
HomeBase is set to Fixed BPS.
Make sure the RS-232 cable is properly attached to the HomeBase and host
computer. Also, check to ensure that the cable is configured properly.
