Battery

1. If your battery is new or has been in storage for a long time,

you may need to charge it two or three times to achieve

optimum performance levels.

2. For the best battery performance and accuracy of the fuel

gauge, completely discharge the battery, then make a

complete fast charge cycle (non-operating), and

completely discharge the battery again.

3. You must ensure that the charging cycle is not interrupted

by a battery discharge, and the discharge cycle is not

interrupted by battery charging.

4. Storage temperature range (the storage time is longer than

six months ) is: -20 ° C to 45 ° C. Storage temperature

range(the storage time is shorter than or up to six months )

is : -20 ° C to 60 ° C.

5. To insure safe charging, the temperature should keep 0 ° C ~

40 ° C inside the OFFS. If the temperature is exceeded, the

charging would be stopped.

The operation is to adjust the two fibers, so that they are in the

deviations in the horizontal (x-axis) and vertical (y-axis)

directions, which are called radial offset. The align ment

operation controls the radial offset within the allowable range.

This part gives instructions on how to achieve low splice loss in

different environment conditions .

a) The recommended parameter group is decided according to

the fiber gap of arc test. The gap length: 015~025.

b) P arameter modification in different circumstance s.

Modify the pre-fusion c u rrent and the fusion c u rrent in the

discharge parameter group, and make the value of arc test meet

the requirements in step b , thus gaining a low loss . The

parameters will reduce at a high temperature and increase at a

low temperature.

Fiber Operation

Operation

Step 1 : Before splicing, thread the fiber through the optical

fiber protection sleeve.

Step 2 : Remove fiber coating, and then brush the bare fiber

with alcohol-soaked cotton swab. The typical bare

fiber length is 20mm.The concentration of the alcohol

should heavier than 905.

Step 3 : Cut the bare fiber using the cleaver. The typical value

of the cleaver length is 10mm~16mm.

Step 4 : Open the shield and fiber holder clamp carefully. Set

the fiber in the V-groove and the fiber holder on the

holder mount. At the same time, note that the tip of

the bare fiber does not touch anything. Make sure

fiber is at the bottom of the V-groove. If not, reset the

fiber.

21

Step 5 : Set the other fiber in the same way. Put the shield

down carefully.

Note:

a) Set the other fiber in the same way. Put the shield down

carefully.

Figure 7-7

b) The tip of the coating fiber should keep a distance from the

bare fiber mount.

(1) Strip , clean and cleave the optical fibers.

(2) Open the shield.

(3) Lift the fiber clamps.

(4) Place the optical fibers in the V-grooves.

(5) Carefully close the V-groove clamps. Ensure the bare

fibers are seated at the position between the V-groove and

the electrodes.

(6) Carefully close the fiber clamps and then the shield.

(7) Decide

if

the end face of fibers is good or bad.

( 8 ) Press the key. The fibers move forward to their initial

gap. Do gap adjustment. If either of the two end face

angles is more than the preset value, an error occurs. Press

the

N otes ：

1. Auto splicing mode is convenient, so we advise the user to

take the auto splicing mode.

2. The splicer has the checking function of fiber cutting angle

and fiber end face, when it works in Semi-auto or a uto splicing

mode . The quality of fiber end and face has enormous impact

on the loss of the contacting point; so efforts should be mad as

possible to make the end face plane, and the angle of the place

with the fiber cross-sectional plane should be less than 1◦.

Cleaning V-groove

V-groove

If there is dust on the V-groove, the bare fiber alignment

operation may produce a big splice loss. Clean the V-groove in

the following steps.

(1) Open the shield .

(2) Cleave a bare fiber and push the tip of this fiber from the

V-groove’s one end to the other end.

(3) If the above method cannot clean the V-groove, you can

use an alcohol-soaked cotton swab to brush the groove to

get rid of the dust.

The surface of the objective lens must be kept clean. Dust on

(1) Turn off the power.

(2) Use a cotton swap soaked with pure alcohol to clean the

lens

’

s surface from center toward rim.

(3) Turn on power. Make sure dust cannot be seen on the LCD

screen.

8.2

8.2 Cautions

Cautions

(1) The splicer is designed for optical telecommunication

fiber s . Don't insert any other type of object in the fiber

clamps or arc center.

(2) Make sure the main body of the splicer is ground ed during

use.

(3) During discharge, the re is a high voltage of several

thousand voltages between the electrodes . So don ’ t touch

them . If there are drops of water on the splice’s main body,

dry it thoroughly before use.

(4) When alcohol drops (including hand grease etc) are

adhere d to the electrodes, accidental discharge might occur.

However, after discharging several times, such liquids will

disappear and normal discharge will proceed.

(5) Do not use the splicer in the environment full of

combustibles (e.g. FREON etc). Otherwise bad splice or

accidents might happen .

(6) Never use any type of solvent other than pure alcohol

when clean ing parts of the machine or fiber s . When

29

wip ing the lens with cotton stick (hav ing be en dipped in

alcohol), move it in one direction instead of back and

forth.

(7) Keep the LCD screen away from the sun and high heat

source s .

(8) Turn off the power switch before power cable is

connected.

(9) The period between two consecutive power-on operations

should be longer than 30 seconds.

b. An electric al arc is produced by electrodes. Two fiber end

profile s are fused into ball shape.

If the electrode's deviation is within 1 0, no adjustment is needed. The

electrodes location adjustment requires high skill. It should be done

by a technician. If the value of "GAP" is between 15 and 25, the arc

power is suitable for fiber splicing . I f the value of “ GAP ” is less than

this range , please increase " Prefuse Power " and " Fuse Power " ,
