Operation

  1. Power On/Off
  • Press “On” key 2 seconds to start the equipment. LCD displays operating wavelength, battery voltage and modulation state. When you open the device, it works on 1310 nm wavelength and continuous light output state; press “off” key 2 seconds to close the equipment. The system defaults auto-shutdown, auto shutdown logo is displayed on the screen.
  • Open and turn off the automatic shutdown function: Press “off” button on the screen, auto-off mark disappear, which shows the automatic shutdown function is closed; and then press “off” button, automatic shutdown logo  is displayed on the screen at this time has indicated that the automatic shutdown feature open. If there is no operation for 10 minutes, the equipment will automatically shutdown.
  1. Wavelength switch function

Press “λ” button when power on, you can switch different wavelengths, and LCD screen displays the different output wavelength.

  1. Modulation output

Press the “Mode” button, you can achieve the modulated light 270Hz, 1 kHz, 2 kHz, 330Hz, 650nm red light 2Hz, —AU automatic wavelength identification mode (It can be used with the help of corresponding power meter, red light doesn’t have automatic wavelength identification mode), continuous light output. At the same time, on the LCD screen the equipment will show the corresponding modulation frequency of the state.

  1. Backlight

Press “” button to turn the backlight on or off. When the backlight is on, the sign  will display on the screen, otherwise this sign disappear.  If the backlight is in a closed state, the operation of any function key will open the 8 seconds’ backlight except pressing “on” button.

  1. Under-voltage

When the battery voltage is low, the power indicator become , when the battery voltage is lower than warning voltage, the equipment will alarm “Low voltage” every 20 seconds. When the battery voltage is lower than protection voltage, it will be in auto turn-off state. The equipment should be charged in time, charging time is about 4 to 6 hours, please observe the charger, if the charging indicator light becomes from red to green, which means the battery is full.

  1. Clean

When the equipment is not in use, the user should immediately cover the dust cap to keep the adapter clean.

Faults & Solutions

Faults
Reasons
Solutions
The instrument cannot be switched on  The battery is under low voltage  Charge the battery at once
No optical  power output The earthen core of the connector is broken  Replace the

connector

The optical power is decreased Connector and the inner light caudal fiber earthen core are dirty Clean the earthen core using absorbent cotton with alcohol

 

  1. Advertent Items

Please pay attention to the followings in order to keep the performance of the instrument and prolong its service time.

  • The instrument should be avoided of mechanical oscillation, collision, fall off and any other mechanical damage.
  • The light output connectors should be avoided the touch of the hard objects, dirty objects, acid, alkali and other caustic objects. Please cover the dustproof cap to avoid the dust and other bad chemical objects.
  • Please clean the fiber jumper earthen port using alcohol and operate it after the alcohol is air-dry.
  • It is forbidden that the user looks at the light output end directly when you operate the instrument to avoid the light burn the eye and skin.
  • Clean the ceramic core regularly
  • The battery should be taken out if the instrument is out of operation for a long while, otherwise, the service time of battery will be affected.

Attention: The light source maybe hurt to eyes, so it is forbidden that the user looks at the light output end directly when you operate the instrument in order to avoid the light burn the eyes!

Note: If you use dry battery, do not recharge the battery. That is dangerous!
