2.0 Notes on safety
Prior to starting up the headlight ATMOS® HL 21 LED, read these operating
instructions carefully.
ATMOS cannot guarantee perfect functioning neither will it be liable for damage
to people or property if:
• Any non-original ATMOS parts are used.
• The instructions for use contained in these operating instructions are disregarded.
• Assembly, resetting, alterations, extensions and repairs are not carried out
by people authorised by ATMOS.
No warranty rights shall exist in the event of damage or failure caused by the use of
non-ATMOS accessories or non-ATMOS consumables.
Please make sure that the ATMOS® HL 21 LED is used in the EMC area described
in the Annex.
Only use the charging power pack supplied by ATMOS.
Exclusively use the headlight ATMOS® HL 21 LED in connection with the rechargeable
ATMOS® LED battery or ATMOS® current sources.
Separation of the charging power pack from the supply is only guaranteed
with the charging power pack being disconnected from the power socket.
Prior to each application, check the device's functions and its proper condition.
Damaged cables must be replaced immediately!
During each application, pay attention to proper t of the headlight ATMOS® HL 21 LED.
Note: The headlight ATMOS® HL 21 LED is not sterile! This fact might be important
for medical operations.
Always make sure that you do not shine in patient's eyes resp. that the patient does
not look directly into the light exit as, otherwise,
EYE INJURIES MIGHT BE THE CONSEQUENCE.
Charging of the LED battery must be checked regularly as the light expires very
fast when the battery gets fl at.
When the headlight ATMOS® HL 21 LED is applied by several users, regular
cleaning and disinfection is necessary.
When not in use, switch off the headlight ATMOS® HL 21 LED.

4.3 Functionality of the rechargeable LED battery
4.3.1 Capacity indication
Charging of the LED battery must be checked regularly as the light expires
very fast when the battery gets fl at. We recommend to change resp. charge
the battery when the capacity is <50%.
As long as the test button (, g. 5) of the rechargeable LED battery is pressed, the battery capacity is
shown for about 3 seconds (, g. 5, green LEDs for levels 1 ... 5).
4.3.2 Charging the LED battery
Use the primary adapter tting for your power supply (Euro/US/ UK/Aus). See information
enclosed to the charging power pack.
To charge the LED battery, separate it from the headlight ATMOS
®
HL 21 LED.
Join round connector of the power pack cable with the socket (, g. 6) on
the LED battery.
During the charging process, the current battery capacity is indicated
(, g. 5, LEDs for levels 1 ... 5). The battery is fully charged when all 5 LEDs expire again.
During charging, operation of the headlight is impossible!

80 MHz to 800 MHz
D = 0,35 √P
800 MHz to 2,5 GHz
D = 0,7 √P
0.01 0.035 m 0.035 m 0.07 m
0.1 0.11 m 0.11 m 0.22 m
1 0.35 m 0.35 m 0.70 m
10 1.11 m 1.11 m 2.22 m
100 3.5 m 3.5 m 7.0 m
For transmitters for which the maximum nominal output isn't indicated in the above table, the
recommended separation distance d in meters (m) can be determined using the equation
belonging to the respective column whereas P is the maximum nominal output of the transmitter in
watts (W) acc. to manufacturer's speci cation.
NOTE 1
With 80 MHz and 800 MHz the higher frequency range applies
NOTE 2
These guidelines may not be applicable in every case. The propagation of electromagnetic sizes is
infl uenced by absorptions and refl ections of buildings, objects and people.
