SAFETY AND GENERAL INFORMATION
• Use of a non-recommended attachment to a battery charger
may result in a risk of fire, electric shock, or injury to
persons.
• Make sure the battery charger power cord is located so that
it will not be stepped on, tripped over, or subjected to
damage or stress.
• An extension cord should not be used with any battery
charger unless absolutely necessary. Use of an improper
extension cord could result in a risk of fire and electric
shock. If an extension cord must be used, make sure that:
•
The pins on the plug of the extension cord are the same
number, size, and shape as those on the plug of the
charger.
•
The extension cord is properly wired and in good
electrical condition.
•
The cord size is 18AWG for lengths up to 100 feet and
16AWG for lengths up to 150 feet.
•
Do not operate any battery charger if it has received a sharp
blow, has been dropped, or has been damaged in any way;
take it to a qualified service technician.
•
Do not disassemble a battery charger; take it to a qualified
service technician when service or repair is required.
Incorrect reassembly may result in a risk of electric shock
or fire.
•
Maximum ambient temperature around the power supply or
transformer of any battery charger should not exceed 40°C
(104°F).
•
The output power from the power supply or transformer
must not exceed the rating given on the Desktop Dual-
Pocket Charger.
•
The disconnection from the line voltage is made by
unplugging the power supply from the AC receptacle.
•
To reduce risk of electric shock, unplug any battery charger
from the outlet before attempting any maintenance or
cleaning.
For optimum charging performance, turn off the radio product
while charging it in any battery charger.
Hearing Aid
Compatibility
• When some mobile phones are used with certain hearing
devices (including hearing aids and cochlear implants),
users may detect a noise which can interfere with the
effectiveness of the hearing device.
Some hearing devices are more "immune" than others to
•
this interference noise, and mobile phones can also vary in
the amount of interference noise they may generate at any
vi
given time. ANSI standard C63.19 was developed to
provide a standardized means of measuring both mobile
phone and hearing devices to determine usability rating
categories for both.
• Ratings have been developed for mobile phones to assist
hearing device users find phones that may be compatible
with their particular hearing device. Not all mobile phones
are rated for compatibility with hearing devices, but mobile
phones that are rated should have the rating available. This
rating may depend on the position of a retractable antenna.
• Results will vary depending on the user's hearing device
and individual type and degree of hearing loss.
• If a hearing device is particularly vulnerable to interference
noise, even a mobile phone with a higher rating may still
cause unacceptable noise levels in the hearing device.
Evaluate your personal needs by trying out the mobile
phone with your hearing device.
• "M" Rating: Mobile phones rated M3 or M4 meet FCC
requirements for hearing aid compatibility and are likely to
generate less interference to hearing devices than phones
that are not labeled. (M4 is the "better" or higher of the two
ratings.)
• "T" Rating: Mobile phones rated T3 or T4 meet FCC
requirements for compatibility with telecoil-type ("T
Switch" or "Telephone Switch") hearing devices and are
likely to be more usable with such hearing devices than
unrated phones. (T4 is the "better" or higher of the two
ratings.)
• Hearing devices may also be measured for immunity to
interference noise from mobile phones. In some cases,
hearing devices can be modified or "hardened" to improve
operation with a mobile phone. Your hearing device
manufacturer or hearing health professional may help you
improve the interaction of your mobile phone and hearing
device. Not all hearing devices are rated for compatibility
with mobile phones, but hearing devices that are rated
should have the rating available. Be sure to evaluate your
personal needs by trying out this mobile phone with your
specific hearing device, using both antenna positions if this
mobile phone is equipped with a retractable antenna.
