The CHARGING AUXBATT LED does
not come on when I insert a battery
pack into the Dolphin HomeBase. Check the power connections on the Dolphin HomeBase. Also check to
ensure the battery pack is properly seated.
The CHARGING AUXBATT LED
constantly changes from RED to
ORANGE to GREEN. The NiMH battery pack may need to be replaced. Insert a new battery pack
into the Dolphin HomeBase's auxiliary battery well.
The CHARGING MAIN BATT LED is
on, but the Dolphin terminal will not
communicate. Check the cable connections to other devices. If you are connecting to
another DCE device, be sure you're using a null modem cable. Try a
previously tested cable if you suspect a bad cable.
Check your communications program in both the Dolphin terminal and the
RS-232 device with which you are communicating. Verify that the baud rates
are set properly.
