Hardware
Replacing Hand Controller Batteries (wireless option)
Depress the battery cover latch (on the rear of the hand controller case) and slide off
Remove old batteries and replace with two new AA alkaline batteries (Duracell MN1500 or
equivalent). Make sure the polarity of batteries matches the marking on case. Replace battery
cover. Note: in order to prolong the life of batteries they should be removed from the hand
controller when it is not in use.
Cleaning display lens
The red display lens is made from an acrylic plastic and as such it can be easily scratched. Care
must be taken to keep dust and dirt from accumulating on the surface. Periodically blow or brush
off the lens using a product such as "Dust Off' a compressed gas duster or a camel hair lens
brush. When the lens requires more than that, first dust as above then carefully clean with a
product such as Windex and a soft facial tissue.
Lubrication of the Motor/gearbox
Under normal use the lubrication should last for the life of the system. Should you suspect that
lubrication is called for contact Ramona Technology for lubricating instructions. If you choose you
may return the motor assemblies to the factory and they will be inspected and lubricated for a
nominal charge.
Firmware
Upgrading the Firmware and Object Database
Upgrading the controller's firmware or database requires using the included RS-232 cable and
placing the controller in the Auto-Load mode. This mode is entered during normal power-up when
the Hand Controller is not connected. The system will stay in this mode for 10 seconds after
power-up at which time the controller will Auto-Boot into the current firmware.
Full instructions for downloading new firmware and databases will be placed at ramonatech.com
Check this website often as firmware and database upgrades will be posted with a version
number to let you know if you have the most current version.
If you do not have access to the Internet, contact Ramona Technology by mail and the update will
be mailed to you on a floppy disk or CD-ROM
If you choose you may return the controller to the factory and the system will be updated for a
nominal charge.
NOT~: Firmware and Database upgrades require a computer running Microsoft Windows 95 or
later.
