1.0 Purpose and Features
1.1 Purpose
The headlight is used for examination, diagnostics and surgical operations for multifarious
uses including microsurgery.
1.2 Features
•50,000 hours of LED life provides for a maintenance free device with an end life of
approximately 20 years.
•The unit has infinite mobility, not confined by access to power sockets, and its charge will last
more than 4 hours at full intensity.
•Its light beam is extremely homogeneous and free of imperfections.
•Its high CRI rating of 92 is very desirable in color-critical applications such as neonatal care,
medicine and surgery, as it shows the true colors of tissues and skin, thereby reducing the
time to diagnosis and surgery.
•The light-weight battery packs have a retention clip to be used on the user’s belt or pocket.
•The wall mounted Battery Charger comes with a Charge Monitor that alerts the operator when
the Battery is fully charged.
•The unit comes with two (2) Battery packs, allowing for “Hot Swap” and the extension of its
operating time to > 8 hours.

3.0 Operating Instructions
3.1 Charging the Battery
1. Plug the charger’s male connector into the receptacle on the Battery pack.
2. Plug the AC connection into a 100-240 VAC source.
3. The charger indicator light will illuminate red while charging and turn green when charging
is complete (approximately 2.5 hours).
4. An 85% partial charge may be performed in 2 hours.
5. Disconnect the charger from the AC source and unplug the charger from the control unit.
3.2 Illuminator and Headband Operation
1. The illuminator unit comes with an integral pendant cable assembly.
2. The cable should be routed and snapped into place through a set of two cable clips. For
dual ratchet headsets one is located on the top on the crown and one on the rear of the
headband. The user has the choice of using the set on the left or the right.
3. For softband/velcro headsets, the cable should be routed through two clips along the
circumference.
4. The illumination spot size may be adjusted by turning the grooved dial on the headlight.
5. The linkage assembly on the headband allows for personal positioning control. The joystick
is used to further adjust the position of the light beam.
3.3 Control Unit / Battery Pack Operation
1. Assure the pendant Cable Assembly is plugged into the Control Unit/Battery pack
receptacle. There are red orientation dots that must be aligned.
2. Clip the control unit where desired or place in a pocket.
3. Turn the ON/OFF and intensity control knob clockwise to turn unit On (switch will close).
This knob also controls the intensity.
4. To turn unit Off, turn control knob counterclockwise until switch opens.
5. When battery has discharged to a level too low to maintain operation, the Illuminator will
dim or flicker and the green LED on the control panel will turn off.
6. The unit’s operational time could be extended from 4 hours at full intensity to greater than 8
hours by using the illuminator at half intensity.

7.0 Color Rendition Index (CRI)
The color rendering index (CRI), with a scale from 0 to 100 %, is a quantitative measure
of the ability of a light source to reveal the colors of various objects faithfully in
comparison with an ideal or natural light source like the light from the sun. Light sources
with a high CRI are desirable in color-critical applications such as neonatal care,
medicine and surgery, as it shows the true colors of tissues and skin, thereby reducing
the time to diagnosis and surgery.
The IsoLED Plus+ unit has a high CRI of 92, which brings it close to the optimum value
of 100, and is one of the few units in the global market with this specification.

10.0 APPENDIX A – BATTERY MAINTENANCE
Users should be aware of the performance and limitations of Ion-Lithium rechargeable batteries;
the leading parameters are capacity and number of charge-discharge cycles.
As the battery gets older, the battery takes its time to charge even if there is little to fill.
Figure A1 illustrates the charge time of a new Li-ion with a capacity of 100 percent against an aged pack
delivering only 82 percent. Both take roughly 150 minutes to charge.
Figure A1: New and aged Li-ion batteries are charged.
Both packs take roughly 150 minutes to charge. The new pack charges to 1,400mAh (100%) while the aged
one only goes to 1,150mAh (82%).
Additionally, Full discharge cycles will impact the battery’s number of charging cycles, as well as
charge/discharge rates and temperature. Avoid high and low State of Charge (SoC); 30 % to 80
% is appropriate. Maximum voltage should be limited to 4.2 V/cell.
Refer to Table A1 below for general Li-ion Battery care.

Table A1: Li-Ion rechargeable Battery care
Battery care Lithium-ion rechargeable Batteries
Best way to
charge Partial and random charge is fine; does not need full charge; lower
voltage limit preferred; keep battery cool.
Charge
methods
Constant voltage to 4.20V/cell; no trickle charge; battery can, no trickle
charge, battery can stay in charger
Rapid charge = 3h (recommended)
Fast charge = 1h
Discharge Prevent full cycles, apply some charge after a full discharge to keep the
protection circuit alive.
How to prolong
battery
Keep cool. Operate in mid SoC of 30–80%. Prevent ultra-fast charging
and high loads (most Li-ion)
Storage
Store at 40% charge in cool place (40% SoC reads 3.75–3.80V/cell). Do
not go below 2.0V/cell.
Disposal Low toxicity. Can be disposed in low volume. Best to recycle.
Table A2: Estimates the number of discharge/charge cycles Li-ion can deliver at
various DoD levels before the battery capacity drops to 70 percent. DoD
constitutes a full charge followed by a discharge to the indicated state-of-charge
(SoC) level in the table.
Depth of discharge
Discharge cycles
Table A2: Cycle life as a function
of
depth of discharge.* A partial
discharge reduces stress and
prolongs battery life, so does a
partial charge. Elevated
temperature and high currents also
affect cycle life.
Note: 100% DoD is a full cycle;
10% is very brief. Cycling in mid-
state-of-charge would have best
longevity.

The following Table A3 provides questions and answers for Isolux’s rechargeable Li-ion
batteries’ care
Table A3 – Questions and Answers on Isolux’s Battery Maintenance
QUESTIONS
ANSWERS
How should I prepare a new battery? Apply a topping charge before use. No
priming needed
Can I damage a battery with incorrect
use? Keep partially charged. Low charge can turn off protection circuit
Do I need to apply a full charge? Partial charge better than a full charge
Can I disrupt the charge cycle? Partial charge causes no harm
Should I use up all battery energy before
charging? Deep discharge wears the battery down and
reduces its number of charging cycles.
Do I have to worry about “memory”? No memory
Do I remove the battery when full? Not necessary; charger turns off
How do I store my battery Store in cool place partially charged
Does battery heat up on charge? Must stay cool or slightly warm
How do I charge when cold? Do not charge below freezing
Can I charge at hot temperatures? Do not charge above 50°C (122°F)
What should I know about chargers? Battery must stay cool; no trickle charge
when ready
Batteries In Storage or in Battery packs Charge Batteries for 10 minutes when not in
use every 4 weeks.
What to do after daily use
After use, at the end of the day, plug the
Battery pack to the Charger.
