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.

Emissions and immunity information

Electromagnetic emissions
The handle and charging accessory is intended for use in the electromagnetic environment specified below. The customer or user of the handle and charging accessory should assure that it is used in such an environment.

Electromagnetic immunity
The handle and charging accessory is intended for use in the electromagnetic environment specified below. The customer or the user of the handle and charging accessory should assure that it is used in such an environment.

Note1 : At 80 MHz and 800 MHz, 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 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.
bovver 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.

For some services, only the uplink frequencies are included.
The carrier shall be modulated using a 50 percent duty cycle square wave signal.
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.
