Introductory information
Introduction
Thank you for purchasing the Welch Allyn 719 Series Lithium Ion Power Handle. The
handle is intended to be used as a power source for all Welch Allyn standard instrument
heads. The 719 series represents a new generation of handles from Welch Allyn. Taking
advantage of new battery technology, the 719 series provides you double the on-time in
a smaller and lighter weight package. Smarter battery technology means that “memory”
is no longer an issue. What’s more, the 719 reminds you to recharge with its low battery
indicator. The soft rheostat section provides a sure grip and the overall design is
ergonomically sound.

aField 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.
bOver 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.

For transmitters rated at a maximum output power not listed above, the recommended separation distanced in meters
(m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output
power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.

a For some services, only the uplink frequencies are included.
b The carrier shall be modulated using a 50 percent duty cycle square wave signal.
c As an alternative to FM modulation, 50 percent pulse modulation at 18 Hz may be used because while it does not
represent actual modulation, it would be worst case.
Warranty
The 719 series Power Handle and USB Charging Accessory is guaranteed by Welch Allyn
against all manufacturing defects for one year. Welch Allyn will repair or replace, free of
