Set-up and Operation
Instructions for Use
The Solid State Portable Headlight (REF 46070), consisting of Portable
Headlight with soft terry cloth headband (REF 46000) and charger/direct
power source (REF 74170). The Solid State Portable Headlight is designed
to operate off the battery or direct power source. The headlight is provided
fully assembled to operate in the portable operation mode. All headlights
are shipped with the batteries discharged. Charge the batteries prior to
use. Once the unit is charged, turn the power switch, located at the top of
the luminaire, to the on position. To operate the headlight using the direct
power source, insert the charger/direct power source (REF 74170) into the
input port located on the top of the luminaire (see photo below). To charge
the battery pack, connect the charger/direct power source (REF 74170) into
the top of the luminaire (see photo below). To adjust the spot size, rotate
the front section of the luminaire. To adjust the headband, simply move the
Velcro adjustable headband to a comfortable position.
Use the Solid State Portable Headlight to provide illumination while
performing a number of activities in the physician’s office, hospital, or
emergency environment such as minor suturing, general exam, and foreign
body removal.
Maintenance
Each month examine cords and connections. The user can perform battery
and/or headband replacement on an as needed basis. Return the unit to an
authorized Welch Allyn Technical Service Department or distributor for
additional servicing. See “Service and Warranty Information” section.
Battery Charging
The fully drained battery will reach a 90% charge retention in approximately
three hours of continuous charging. This is approximately 25% longer if the
charging is happening at a temperature less than 15° C. Proportional usage
will require a proportional charge time such as if the product is used for 15
minutes, charge the battery for 45 minutes to reach a 90% capacity.
Overnight charging brings the battery to its 100% full capacity.
Charging the unit while operating will significantly increase the charge time
to over 12 hours to obtain a 90% charge level.
This battery pack does not exhibit any memory problems that exist with
NiCad batteries. However, like other products where batteries are used,
remove the battery from the product when the product is in storage or
when not in use for extended periods beyond 6 months. If the battery is left
in the product for extended periods of time, the battery will drain down to
an unusable level and require charging prior to use.

Headband Replacement
