Use With Hearing Aids; Hearing Aid Compatibility - Motorola ES400 Regulatory Manual

Use with Hearing Aids

When some wireless devices are used near some hearing devices
(hearing aids and cochlear implants), users may detect a buzzing,
humming, or whining noise. Some hearing devices are more immune
than others to this interference noise, and wireless devices also vary
in the amount of interference they generate. In the event of
interference you may want to consult your hearing aid supplier to
discuss solutions.
The wireless telephone industry has developed ratings for some of
their mobile phones, to assist hearing device users in finding phones
that may be compatible with their hearing devices. Not all phones
have been rated. Motorola terminals that are rated have the rating
included on the Declaration of Conformity (DoC) at
http://www.motorola.com/Business/
US-EN/Document+Library/Declaration+of+Conformity.
The ratings are not guarantees. Results will vary depending on the
user's hearing device and hearing loss. If your hearing device
happens to be vulnerable to interference, you may not be able to use
a rated phone successfully. Trying out the phone with your hearing
device is the best way to evaluate it for your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are
likely to generate less interference to hearing devices than phones
that are not labeled. M4 is the better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are
likely to be more usable with a hearing device's telecoil ("T Switch" or
"Telephone Switch") than unrated phones. T4 is the better/higher of
the two ratings. (Note that not all hearing devices have telecoils in
them.)
Hearing devices may also be measured for immunity to this type of
interference. Your hearing device manufacturer or hearing health
professional may help you find results for your hearing device. The
more immune your hearing aid is, the less likely you are to
experience interference noise from mobile phones.

Hearing Aid Compatibility

This device is marked HAC showing compliance with the applicable
requirements of FCC Part 68 and CS03-Part 5.
This device is not HAC compliant during Voice Over IP (VOIP) calls.
Radio Frequency Interference Requirements-FCC
Note: This equipment has been tested and found
to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable
protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications. However there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician for help.
Radio Transmitters (Part 15)
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
