Selecting the wavelength

You can use the “

λ

” key to select individual wave-

lengths or the Dual mode (ALL) (Circular func-
tion). In single-wavelength mode, you can select
from two switch positions: “1310 nm” and
“1550 nm” (“780 nm” and “1300 nm”). The third
position (“ALL”) activates both wavelengths si-
multaneously.
