MANUAL OPERATION
molbox RFM is designed to offer the optimum balance between simple, intuitive operation
and the availability of a wide variety of functions with a high level of operator discretion. The
local operator interface is through the front panel's 2 x 20 character alpha-numeric display
and a 4 x 4 multi-function keypad. Remote operation by RS232 or IEEE-488 interface is also
available (see Section 4).
