Turn on the HAC Setting
When the HAC setting is on, your phone sends the audio from your phone calls to the telecoil rather than
to the microphone of your hearing aid. You are likely to hear calls much better because volume is
increased and background noise and feedback are diminished. The HAC setting improves only the calls
you listen to through the earpiece. It does not affect calls heard on the speakerphone or a headset. It’s
better to turn off the Bluetooth function when the HAC setting is on. HAC requires extra battery power, so
watch your battery consumption when it’s turned on.
Caution:
Do not turn on the HAC setting unless you use a hearing aid with a telecoil. Using this setting without a
hearing aid or with a hearing aid without a telecoil may be harmful to your hearing.

If you encounter problems while using the phone, or if it performs erratically, you can consult the
information in the chart below. If your particular problem cannot be resolved using the information in the
chart, contact the dealer of handset.
Problem
Possible causes
Possible solution
Poor reception
The network signal is too weak at your
current location, for example, in a basement
or near a tall building, because wireless
transmissions cannot effectively reach it.
Move to a location where the network signal
can be properly received.
The network is busy at the current time (for
example, during peak times, there may be too
much network traffic to handle additional
calls).
Avoid using the phone at such times, or try
again after waiting a short time.
You are too far away from a base station for
your service provider.
You can request a service area map from your
service provider.
Poor network trunk quality on the part of your
service provider.
Press the End Key and dial again. You may
be switched to a better-quality network trunk
or phone line.
Poor local telephone line quality.
Press the End Key and dial again. You may
be switched to a better-quality network trunk
or phone line.
Unable to select
certain features.
Your service provider does not support these
features, or you have not applied for services
that provide these features.
Contact your service provider.
Battery will not
charge.
The battery or battery charger is damaged.
Contact the dealer.
The phone’s temperature is below 0℃ or
higher than 45 ℃.
Adjust the battery charging environment to
avoid extremes of temperature.
Poor contact between the battery and charger.
Check all connectors to make sure all
connections have been properly made.
The standby time is related to your service
provider system configuration. The same
phone used with different service providers’
systems will not provide exactly the same
length of standby time.
If you are located in an area where signaling
is weak, temporarily switch off the phone.
The battery is depleted. In high-temperature
environments, battery life will be shortened.
Use a new battery.
If you are not able to connect to the network,
the phone will continue to send out signals as
it attempts to locate a base station. Doing so
consumes battery power and will
consequently shorten standby time.
Change your location to one where the
network is accessible, or temporarily turn off
your phone.
You cannot switch
your phone on.
Battery power has been depleted.
Recharge the phone’s battery.

FCC Compliance
•
This mobile phone 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.
•
•
This device 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 to 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.
Changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
Radio Frequency (RF) Energy
This device meets the government’s requirements for exposure to radio waves.
This phone is designed and manufactured not to exceed the emission limits for exposure to radio
frequency (RF) energy set by the Federal Communications Commission of the U.S. Government.
The exposure standard for wireless device employs a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg. Tests for SAR are conducted using
standard operating positions accepted by the FCC with the device transmitting at its highest certified
power level in all tested frequency bands. Although the SAR is determined at the highest certified power
level, the actual SAR level of the phone while operating can be well below the maximum value. This is
because the device is designed to operate at multiple power levels so as to use only the poser required to
reach the network. In general, the closer you are to a wireless base station antenna, the lower the power
output.
The highest SAR value for the device as reported to the FCC when tested for head, as described in this
user guide, is 1.00W/kg for UMTS band II.
While there may be differences between the SAR levels of various phones and at various positions, they
all meet the government requirement.

Z431 User Manual
The FCC has granted an Equipment Authorization for this device with all reported SAR levels evaluated
as in compliance with the FCC RF exposure guidelines. SAR information on this device is on file with
the FCC and can be found under the Display Grant section of http://www.fcc.gov/oet/fccid after
searching on FCC ID: Q78-Z431.
For body operation, this device has been tested and meets the FCC RF exposure guidelines for use the
positions the device a minimum of 1.5cm from the body. Use of other enhancements may not ensure
compliance with FCC RF exposure guidelines.
