cross-over cable. If there are multiple COM ports, use COM1. (The version upgrade
program may not operate properly with other than the COM1 port).

parameters to 9600 baud, 8 bit, Parity none.
3) While pressing the INIT switch at the rear of the instrument, switch ON the power to
the instrument. Release the INIT switch between 1 - 5 seconds after switching ON the
instrument.
4) When the message "Press Enter key to proceed" is displayed, press the Enter key.

(press [V]).
6) The instrument's LED enters the state described in step 2) of "6.10.2 Upgrade by Way
of RS-232C (1)". Exit the terminal software, and complete the version upgrade by
