• Wavelength selection

The device can emit at three wavelengths: 1310nm, 1490nm, and 1550nm.
It also has an Auto 3L mode in which the 3 wavelengths are emitted sequentially.
To change the wavelength, press the LAMBDA key. Selection options appear in sequence on the screen.
When you select the Auto 3L mode, the device will set the signal modulation automatically.
The optical output power will also be set automatically.

• Signal modulation 

The device allows for modulation of the selected lambda with the following tones: Off, 270Hz, 1KHz, and 2KHz.

• Laser powering On  

This button is used to turn the device laser On and Off.
Using this option you can make changes to the device configuration with the laser off, thereby substantially saving battery.

• Screen

Backlit. Allows saving battery disconnection.
