Cleaning Exterior Surfaces of the 465L
If necessary, the front panel mask and keyboard of the 465L can be cleaned with a
damp cloth. Do not attempt to clean any of the other surfaces of the instrument. Do
not submerge any part of the instrument in water or cleaning solution.

Boot Loader Operation
The main function of a boot loader is to load or update the firmware to the
microcontroller on the Printed Circuit Board (PCB) of an instrument. There are two
types of boot loader setup: hardware and software, described in the following
sections.
When an external MODBUS host device is attempting to
communicate with the instrument over the serial or Ethernet port
while the instrument is starting up, the instrument may halt. In
order to prevent the problem from occurring, ensure that there are
no devices attempting communication with the instrument during
start-up. Once the sign-on message is displayed on the front
panel, it is safe to begin communications.
