Safety Information
WARNINGS!
Use only proper power source.
• Proper AC power source is AC100-240V, 50-60Hz. Check the AC power source
before use. Improper AC power source may cause fuming, electric shock or
equipment damage and may result in personal injury, death or fire.
• AC generators commonly produce abnormally high AC output voltage or irregular
frequencies. Measure the output AC voltage with a circuit tester before connecting
the AC power cord. Such abnormally high voltage or frequency from a generator
may cause fuming, electric shock or equipment damage and may result in personal
injury, death or fire. Make sure the generator is regularly checked and serviced.
• An AC adapter Protection Circuit is included in the AC adapter. If the “High AC
Input” lamp of the AC adapter is lit or the protection circuit in the AC adapter is
tripped, this indicates that the incoming voltage is dangerously high and may cause
injury or damage to the equipment, as mentioned above. When using an AC
generator with AC output voltage of AC220-240V especially, Fujikura Ltd.
recommends the following measures to correct the condition.
1. Connect a step-down transformer between the generator and the AC adapter
in order to lower the AC voltage from AC220-240V to AC100-120V.
2. Or, use an AC generator with AC output voltage of AC100V.
3. Or, use an AC generator that has an inverter circuit to stabilize the output.
Do not modify, abuse, heat or excessively pull on the supplied AC cord. The use of a
damaged cord may cause fuming, electric shock or equipment damage and may result
in personal injury, death or fire.
Connect AC power cord properly to the splicer (inlet) and wall socket (outlet). When
inserting the AC plug, make sure there is no dust or dirt on the terminals. Engage by
pressing the female plug into the splicer (inlet) and the male plug into the wall socket
(outlet) until both plugs are fully seated. Incomplete engagement may cause fuming,
electric shock or equipment damage and may result in personal injury, death or fire.
Do not short-circuit the terminals of AC adapter and optional battery. Excessive
electrical current may cause personal injury due to fumes, electric shock and
equipment damage.

manual.
Splice mode
The 41S has not only standard splice modes, but also automatic modes, AUTO mode.
The AUTO mode consists of [SM AUTO], [MM AUTO], [NZ AUTO] , [DS AUTO] mode.
When using AUTO mode, the automatic arc calibration function is enabled.
The standard modes consists of [SM] for SMF (ITU-T G652), [NZ] for NZDSF (ITU-T G655),
[DS] for DSF (ITU-T G653) and [MM] for MMF (ITU-T G651). This mode requires executing
[Arc Calibration] before splicing.
Automatic arc calibration function
This function calibrates the arc power at every splice. When the automatic arc calibration
function is enabled, performing the [Arc calibration] function before a splice operation is not
necessary. The automatic arc calibration function works in AUTO modes only. It doesn’t
work in the standard splice modes. When using those modes, performing [Arc calibration]
before splicing is strongly recommended.
