I. FCC RF Exposure Co pliance Require ents
The Federal Communications Commission (FCC), with its
action in General Docket 93-62, ovember 7, 1997, has
adopted a safety standard for human exposure to Radio
Frequency (RF) electromagnetic energy emitted by FCC
regulated equipment. Topaz3 / TruTalk subscribes to the
same safety standard for the use of its products. Proper
operation of this radio will result in user exposure far below
the Occupational Safety and Health Act (OSHA) and Federal
Communications Commission limits.
CAUTION - DO OT transmit for more than 50% of total
radio use time (50% duty cycle). Transmitting
more than 50% of the time can cause FCC
RF exposure compliance requirements to be
exceeded.
•When transmitting, hold the radio in a vertical position
with its microphone 2 inches (5 cm) away from your
mouth. Keep the antenna at least 2 inches (5 cm) from
your head and body.
•This device has been approved for use, at a maximum
duty factor of 50%, using the specific belt clip tested for
body-worn SAR compliance. Other belt clips or body-
worn accessories may not comply and should be
avoided. ALWAYS use Maxon, Legacy and TruTalk
authorized accessories: antennas, batteries, belt clips,
speaker mics, etc.
•The radio is transmitting when the red LED on the front
of the radio is illuminated. You can cause the radio to
transmit by pressing the P-T-T bar on the radio.

FCC RF exposure compliance. Failure to observe these
restrictions mean violation.
FCC WARNING: This equipment generates or uses radio
frequency (RF) energy. Changes or modifications not
expressly approved in writing may cause harmful interfer-
ence and void the user's authority to operate this equip-
ment.
II. FCC RF Exposure Infor ation

VII. Getting Started
Charging the NiMH Battery Pack
You will need to charge the battery pack fully before
initial use. For best results from your charging cycle,
follow these tips:
• Ensure the ambient temperature is between 41 and
104° F (5 and 40° C) while charging. Temperatures
outside this range may not fully charge the battery.
• Always switch OFF the transceiver equipped with
a iMH battery pack before charging. Using the
radio during the charging cycle will hinder correct
charging.
• Do not recharge the battery pack if it is already
fully charged. Doing so may cause the life of the
battery pack to shorten or the battery pack may
be damaged.
• If the battery is stored for 2 months or more, it is a
good idea to complete the charge / discharge cycle
two or three times to allow the battery capacity
to return to normal.
• ever dispose of the battery in fire - it can explode
causing personal injury.
• ever attempt to disassemble the battery or remove
its case material or charging contacts. Do not short
the battery terminals.

VII. Getting Started, continued
Charging the NiMH Battery Pack, continued
NOTE: The first few uses from the battery will not
be at normal capacity. After repeating the charge /
discharge cycle two or three times, the battery
capacity will increase to provide full capacity.
1. Plug the AC adapter cable in the adapter jack
located on the rear of the charger, then into
an AC outlet.
2. Slide the iMH battery pack (or the radio
equipped with a iMH battery pack) into the
charging slot.
3. Ensure that the metal contacts on the battery pack
come in contact with the charging terminals.
4. When charging the iMH battery pack alone,
insert the provided plastic spacer (stored in
charger base) into the charging well, then insert
the battery pack.
5. The charger LED will light to advise that charging
has begun. Charge the standard battery pack for
9 hours. REMOVE THE PACK OR RADIO
FROM THE CHARGER.
IMPORTANT NOTE: The charger DOES NOT
TURN OFF AUTOMATICALLY after the charging
cycle has been co pleted. Damage to the battery
or reduced battery life may result if charged in
excess of the recommended charging time.

VII. Getting Started, continued
Attaching and Re oving the Battery Pack
NOTE: After recharging the battery pack, REMOVE IT
FROM THE CHARGER.
The battery pack life is over when its operating time
decreases even though it is fully and correctly
charged. Replace the pack with the manufacturers
recommended model (TruTalk / Legacy ACC-203,
750 mAh or TruTalk / Legacy ACC-204, 1350 mAh).
Average battery pack life from the supplied 750 mAh
battery is 11+ hours; the optional 1350 mAh battery,
19+ hours. This service time is calculated using 90%
standby, 5% transmit and 5% receive time.
After charging the battery pack as described, you are
ready to install it to the radio body. Simply;
1. Match the four grooves of the battery pack with
the guides on the back of the radio.
2. Slide the battery pack up along the back of the
radio until the release latch locks.
To remove the battery pack, push down on the release
latch and slide the pack downward, and away from the
radio.

VII. Getting Started, continued
Installing the Antenna
Screw the antenna into the connector on the top of the
radio by holding the antenna at its base and turning
it clockwise until seated. Do not overtighten.
The antenna should never be used to carry your radio,
or as a base to clip radio accessories. Misuse of the
antenna can cause damage, and reduce your radios
performance.
Installing the Belt Clip
We recommend that the belt clip is installed on the
radio. It keeps the radio from coming in contact with
hot surfaces, and away from your body if heat build-up
occurs with excess transmissions.
Use the two supplied screws to install the belt clip. If
a replacement is needed, use a screw designed to the
exact specifications as the original, to prevent acciden-
tal contact with internal circuitry, or possible personal
injury. ever use glue in conjunction with the provided
screws. Some of the glues components may crack the
radio back panel, causing radio damage and possible
personal injury.
Installing the Speaker Microphone Jack Cover
If you are not using an accessory, install the provided
cover over the speaker microphone jack using the screw
supplied. This will keep the radio water resistant.

14
VII. Getting Started, continued
Attaching the Optional Speaker Microphone
1. Insert the speaker microphone jack into the radio.
2. Use the thumbscrew attachment on the speaker
microphone to make connection to the radio.
NOTE: The radio is not fully water resistant while the
speaker microphone is attached.
