Hearing Aid Compatibility (HAC)
Device Listings
The standard for compatibility of digital wireless devices with hearing
aids is set forth in American National Standards Institute (ANSI)
standard C63.19. ANSI C63.19 contains these two sets of standards:
•An “M” rating from M1 to M4 for reduced radio frequency (RF)
interference to enable acoustic coupling with hearing aids that do not
operate in t-coil mode.
•A “T” rating from T1 to T4 to enable inductive coupling with hearing
aids operating in t-coil mode.
A digital wireless handset is considered hearing aid compatible for
acoustic coupling if it meets at least an “M3” rating under the ANSI
standard. A digital wireless handset is considered hearing aid
compatible for inductive coupling if it meets at least a “T3” rating under
the ANSI standard.
M-Ratings: Devices rated M3 or M4 meet FCC requirements and are
likely to generate less interference with hearing devices than devices
that are not labeled. M4 is the superior/higher of the two ratings.
T-Ratings: Devices rated T3 or T4 meet FCC requirements and are likely
to be more usable with a hearing device’s t-coil than unrated devices. T4
is the superior/higher of the two ratings.
These ratings are not guaranteed. Results will vary depending on the
level of immunity of your hearing device and the degree of your hearing
loss. If your hearing device happens to be vulnerable to interference, you
may not be able to use a rated device successfully. Trying out the device
with your hearing device is the best way to evaluate it for your personal
needs.
When some wireless devices are used near some hearing devices such
as hearing aids and implants, users may detect a buzzing or humming
noise. Some hearing devices are more immune than others to this
interference noise. Wireless devices may also vary in the amount of
interference they generate. The more immune the hearing aid device is,
the less likely one is to experience interference noise from the wireless
device.
Hearing aid devices may also be rated. Adding the ratings of the hearing
aid and the device can predict the usability of the two devices together:
•Any combined rating equal to or greater than six offers the best use.
•Any combined rating equal to five is considered normal use.

These models have been tested and rated for use with hearing aids for
some of the wireless technologies that they use. However, there may be
some newer wireless technologies used in these devices that have not
been tested yet for use with hearing aids. It is important to try the
different features of these devices thoroughly and in different locations,
using your hearing aid or cochlear implant, to determine if you hear any
interfering noise. Consult your service provider or the manufacturer of
the device for information on hearing aid compatibility. If you have
questions about return or exchange policies, consult your service
provider or device retailer.

About the Battery
The CT50 uses a rechargeable 3.6 Vdc Li-ion battery as its main power
source. The battery has a 14.6 watt-hour capacity. Several factors
determine the life of your battery, such as display brightness, display
timeout, input device, extreme temperature, and your usage.
Honeywell recommends that you keep the battery charged at all times to
prevent data loss. When you change the battery, the computer
automatically goes into a power-off state.
Contact your local sales representative for replacement batteries.
Charge the Battery
Make sure you fully charge the battery (Model CT50-BTSC) before you
use your CT50. You can charge the battery before or after you install it in
the CT50. It takes about 6 hours for the battery to fully charge in any of
the accessories.
•Insert the battery into a Quad Battery Charger or the battery well of
an eHomeBase.
or
•Insert the CT50 with the battery installed into an eHomeBase,
ChargeBase, NetBase, Quad Battery Charger, USB Adapter, or
Vehicle Power Adapter.
Caution: The battery used in this device may present a fire or
chemical burn hazard if it is mistreated. Do not disassemble it, heat
it above 100 °C (212 °F), or incinerate it. Dispose of used batteries
promptly. Keep away from children.
Caution: We recommend the use of Honeywell Li-ion battery packs.
The use of any non-Honeywell battery may result in damage not
covered by the warranty.
