7.7. Shuttle Switch
MLS does not prepare numeral keys to input values. Therefore, use the communication function
or shuttle switch for input. The shuttle switch is used for setting main parameters such as wave-
length and optical power, and setting MLS communication parameters, and also monitoring. The
shuttle switch enables to set the present parameters on the display and monitoring.
When the shuttle switch is located in the center, the display shows the present value.
The set values are showed on the parameter display when it turns right and left a little. The
display shows the set value for nearly 1 second when it turns back to the center from that condi-
tion.
The shuttle switch can change by 6 steps from the center to right and left. The CW(Clock wise) is
increment, and CCW(Counter Clock wise) is decrement.
