WARNING
You are cautioned that changes or modifications not expressly approved in this document could avoid you authority to operate this equipment.To reduce the risk of fire or  electric shock,do not expose this apparatus to rain or moisture. To avoid electrical shock, do not open the cabinet. Refer servicing to qualified personnel only.

Precautions for Use

Use batteries
At the same time, can not use different style or different capacitance batteries. And only charge the rechargeable batteries.
Avoiding condensation problems
As much as possible, avoid sudden temperature changes. Do not attempt to use the device immediately after moving it from a cold to a warm location; or to raise the room  temperature suddenly, as condensation may form with in the drive. If the temperature changes suddenly while using the device, stop using it and take out batteries for at least  an hour.
Storage
When long time no use, must take out the batteries to avoid destroying the device.

Install the Battery

1.Pull the battery cover lock| 2.Raise the battery cover

3.Install the battery correctly| 4.Put the battery cover back and lock

On/Off and Permanent On

Press “ ” button to turn on the meter . Press button again for two seconds or more to turn off the meter.
This meter comes with power-saving function; normal boot and ten minutes without any operation, the device will automatically shut down. If you need to shield this function and enable the meter keeps on working, press the button and hold when you boot the
instrument. After two seconds, the meter display will show “PERM” ,which means permanent power on.

Function Selection

Network Cable;
Telephone Wire Testing

After booting, the default function is the optical power meter. Press button, you can cycle Optical
Power Meter – Date Access – VFL – Flashlight- Network Cable/Telephone Wire Testing.

Optical Power Meter

As optical power meter, press “ ” button to select different wavelengths to measure. The standardized wavelengths are 850nm, 1300nm, 1490nm, 1550nm, 1625nm. The unit  display is mW/uW value and dBm value, which can switch by pressing “ ” button.
Longpress “ ” button until the LCD shows up “REF” ,you can set the current power value as a reference value.

Data Storage

In data access interface, LCD will show “ “. The figure and wavelength will display in turn.Press “ ” /* “to check the saved data.Press” “for 2 seconds to save current  wavelength & value(Max:500 traces). If exceeds, the 501 data will cover the first one and soon.

Visual Fault Locator/LED Flashlight

As a visual fault locator, press “ ” button, you can choose the laser remains on or flashing. In the flashing state, the screendisplay “ ” and the flashing frequency is 2Hz.
As aLED flashlight, press “ ” button, you can choose the LED light remains on or flashing in SOS encoding mode. Under SOS function status , the screen display “.

Network Cable/Telephone Wire Tester

Network cable/Telephone wire testing function is used for cabling network, connecting and disconnecting network cable, verifying the line sequence. It starts testing wnen this function is chosen. Eight indicators are used to display the sequence of lines.

Power Indicator

Four levels indication of power detection

Represents the remaining 80%—100% electricity

Represents the remaining 40%—80% electricity

Represents the remaining 20%—40% electricity

Represents the remaining electricity less than 20%

Charge

The device is rechargeable. When use rechargeable batteries and low battery indication is shown on the device, you should promptly shut down and recharge it. Long time  undervoltage will shorten the lifetime of the rechargeable battery.
Connect the AC adapter to the device correctly, it can charge automatically. Besides, computer USB port can also be used for charging. The battery remaining indicator keeps  flashing during charging. It will stop when the charging is finished. The battery has finished the fast recharge and can be used directly. If you do not stop recharging at this  time, the device will continue the trickle charge state, using small current to supply natural discharge. But this process is not more than 48 hours.
The device can still be used while charging. But do not plug in the AC adapter when there is no rechargeable battery inside, or it will cause a high temperature and  combustion, even explosion.

Meter Maintenance

General maintenance
Optical fiber connect the adapter should avoid contacting with hard objects and keep clean.
Should be stored in a dry and ventilated place to avoid moisture.
When unuse for long time,should remove the batteries before storage.
Fault and solution

installed correctly
Immediately shutdown after booting| Check the battery has power or not| Replace or recharge the batteries
Can display, but all operations are invalid| The device program is disordered Reboot|
Cannot charge| Use non-rechargeableable battery.| Reinstall the rechargeable batteries
Garbled| Incorrect reset| Reboot
