2.3.9 Using the charger
ri-focus® LED and clar N 55
Plug the charger into the mains outlet, then connect it to the battery compartment. Once the connection to the battery compartment has been established, the char-
ging indicator on the charger lights up and the batteries are charged.
If the LED on the charger is red, the batteries need to be charged.
If the LED on the charger is green, the batteries are fully charged.
Battery charger specifications:
Input: AC 100 - 240 V
50/60 Hz, 0.3 A
Output: DC 5.8 V/0.25 A
Caution: for use with 3.6 - 4.8 V
Charging time: First charge: minimum of 24 hours
Sunsequent charges: overnight or as needed.
Battery mode:
Approx. 90 min. with fully charged batteries.
If the battery voltage falls below the minimum voltage, the LED will switch off.
If the LED does not illuminate when the power is on, the battery voltage is too low. Batteries must be charged.
Caution:
Only standard rechargeable AAA batteries that meet the IEC 62133 standard may be used with this charger.
Charging non-rechargeable batteries can destroy the batteries or the charger.
The charger may only be used in enclosed spaces.
Unplug the device from power outlet when not in use.
Do not operate the device if the housing, powercord, or plug is damaged.
Do not open the device.
If you do not use the device for long periods of time or take it with you while travelling, please remove the (rechargeable) batteries from the battery compartment.
New batteries should be inserted or the rechargeable battery should be charged when the light intensity of the instrument becomes weaker and could impair the
examination.
For optimal light output, we recommend you always use new, high-quality batteries when changing the battery.
