the age of the battery.
Once the battery is fully discharged, the low battery indicator may flicker.
Replace the battery
1. Hold the instrument handle firmly by the battery section.
2. Turn the rheostat section counterclockwise until it detaches from the battery section.
3. Insert the rheostat section into the new battery section.
4. To connect the two sections, turn the rheostat section clockwise until tight.
5. Ensure that the rheostat section is secure on the battery section of the instrument handle.
Operate the device
1. Connect instrument head to the handle.
2. To turn on, press the On/Off button on the rheostat section and rotate the rheostat section
clockwise (CW).
3. To intensify the light, continue to rotate CW until a stop is reached.
4. To turn off, rotate counter clockwise (CCW). The On/Off button will click when fully off.
NOTE Turn fully off after each use to ensure maximum on-time
from the battery.
Cleaning and disinfecting the device
WARNING Do not soak/saturate the handle assembly or charger.
WARNING Do not immerse handle assembly or charger in any solution.
6 A - English Welch Allyn 719 Series Lithium Ion Handle and USB Charging Accessory

a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the handle and
charging accessory is used exceeds the applicable RF compliance level above, the handle and charging
accessory should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the handle and charging accessory.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications
equipment and the handle and charging accessory
The handle and charging accessory is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or user of the handle and charging accessory can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the handle and charging accessory as recommended below,
according to the maximum output power of the communications equipment.
