Warnings!
lu
Never look directly into optical output ports when the laser source is emitting. The Laser output
of FHS and FHM are Class I. Invisible laser beam may damage your eyes.
So
Do not short-circuit the terminal of AC adapter / charger and the batteries. Excessive
electrical current may result in personal injury due to fumes, electric shock or equipment
damage.
al
-i
Connect DC power cord with the equipment and wall socket properly. While inserting the DC
plug, make sure there is no dust or dirt on the terminals and both plugs are fully seated.
Incomplete engagement may cause fuming, electric shock or equipment damage and may
result in personal injury.
C
or
Do not operate the equipment near hot objects, in hot environments, in dusty/ humid
atmosphere or when condensation is present on the equipment. This may result in electric
shock , product malfunction or poor performance.

There is a battery indicator on the screen to show the remaining charge. There are four possibilities
the indicator may show, full, with 2 blacks, with 1 black and empty. If an empty battery indicator
flashes it means the power is almost out, and that is when you should recharge the batteries by
connect the AC adapter with the instrument. If the discharged batteries reach their limitations after
long-time use, please replace them with new ones. To replace the batteries, please remove the
battery plate on the back of instrument with a screwdriver.
al
-i
When the battery charge is extremely low to supply the necessary power, the instrument will
automatically switched off.
Note: 1 The AC indicator is not displaying when power is supplied by battery.
2 To eliminate the possibility of acid leakage, please take out the battery if the unit is not used for
a long time.
2. AC operation
C
or
If the instrument is mainly used at one location, e.g. in a laboratory or test department, the AC adapter
can be used to power it instead of batteries. There is a DC input jack on the bottom side of the F2HP
instrument When the AC adapter is plugged in, the AC Indicator on the LCD will be displayed.
Note: 1 When AC adaptor is used, make sure do not place un-rechargeable batteries inside.
2 Make sure that local AC voltage is in the range of our operating voltage. E.g. Input:AC 100240V,50-60Hz.

Checking for damage in transit
After unpacking the instrument, check to see whether it was damaged in transit. This is particularly
likely if the outer casing is clearly damaged. If there is damage, do not attempt to operate the
instrument or to repair it without authorization. Doing so can cause further damage and you may
lose your warranty qualification.

VLS-5A/B / Introduction
ns
1 Introduction
So
lu
tio
The VLS-5A/B is compact but powerful visible fault locator designed
troubleshoot on fiber optic cables. Light generated by these units will
escape from sharp bends and breaks in jacketed or bare fibers, as
well as poorly mated connectors. Thus they can identify faults in fiber
optic jumper cables, distribution frames, patch panels, and splice
trays. The VLS-5A/B locates faults visually by creating a bright red
glow at the exact location of the fault on singlemode or multimode
fibers. The VLS-5A/B is powered by three No. 7 batteries.
