Standards Compliance
This product complies with the regulations for PMR446 service and has been
independently approved to meet the requirements of standard ETS 300 296 and other
European standards.
Care and safety with radio transmitters
In order to provide optimal radio performance and make sure human exposure to radio
frequency electromagnetic energy is within the recommended parameters set forth in the
regulations, always adhere to the following procedures:
When operating a portable transmitter, hold the device in a vertical position with the
microphone 4 to 6 inches (10-15cm) away from your mouth. Keep the antenna at least 1
inch (2.5cm) away from your head and body. If wearing the device near your body,
ensure the antenna is at least 1 inch (2.5 cm) away from your body when transmitting.

Electromagnetic interference/compatibility
Nearly every electronic device is susceptible to electromagnetic interference (EMI) if
inadequately shielded, designed, or otherwise configured for electromagnetic compatibility.
In order to avoid electromagnetic interference and/or compatibility problems, turn off your
radio in any location where posted notices instruct you to do so. Hospitals or health care
facilities may be using equipment that is sensitive to external radio frequency energy.
When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio
must be in accordance with applicable regulations per airline crew instructions.
CARE AND MAINTANENCE
OPERATING PRECAUTION
Damaged antenna
Do not use a radio with a damaged antenna. If a damaged antenna comes into contact with
your skin, it could cause a minor burn. Send your equipment to technical service for repair
before using it again.
Batteries
All batteries can cause property damage and/or personal injury such as burns if a conductive
material such as jewelry, keys, or beaded chains touch exposed terminals. The conductive
material may complete an electrical circuit (short circuit) and heat up significantly. Exercise
care in handling any charged battery, particularly when placing it inside a pocket, purse, or
other container with metal objects.
OPERATING WARNING
Replacement parts
Use of replacement parts other than those recommended by the official product distributor
may violate the device certification. Use only the recommended replacement parts.
For vehicles with an air bag
Do not place a portable radio in the area over an air bag or in the field of air bag
deployment. Air bags inflate with high levels of pressure and force. If a portable phone
is placed in the air bag deployment area and the air bag inflates, the phone may be
propelled with great force and cause serious injury to the vehicle occupants.

Potentially explosive environments
This product DOES NOT meet intrinsic safety regulations. Turn off your radio when in
any area with a potentially explosive environment. Sparks in such areas could cause an
explosion or fire resulting in bodily injury or even death.
Batteries
Do not replace or charge the batteries in an area with a potentially explosive
environment. Contact sparking may occur while installing or removing the batteries and
cause an explosion.
Blasting caps and areas
To avoid possible interference with blasting operations, turn off your radio when you
are near electrical blasting caps, in a "blasting area", or in areas posted: “Turn off two-
way radio.” Obey all signs and instructions.
Note: Areas with potentially explosive environments are often, but not always, clearly
marked. They include fueling areas; below decks on boats; fuel or chemical transfer or
storage facilities; areas where the air contains chemicals or particles, such as grain, dust
or metal powders; and any other area where you would normally be advised to turn off
your vehicle engine.
Waste electrical products should not be disposed of with household waste. This
equipment should be taken to your local recycling center for sate treatment.

IMPORTANT SAFETY INSTRUCTIONS
KEEPTHESE INSTRUCTIONS
Before using the battery charger, read the instructions and precautions for the charger and
battery as well as the radio equipment.
PRECAUTION
To reduce the risk of sustaining injuries when using the charger, only charge the original
rechargeable batteries. Other types of batteries could explode, causing injury and harm.
1.- Do not expose the charger to rain or snow.
2.- Do not use the charger if it has received a sharp blow, or has been dropped or
damaged in any way.
3.- Do not disassemble the charger. If it is put back together incorrectly, it could result in
a risk of electric shock or fire.
4.- Never alter the power cable provided with the charger. If the plug does not fit in the
outlet, use an approved adaptor, or install the proper outlet. When unplugging the supply
from the outlet, always pull the plug rather than the cable to reduce the risk of damage
to the cable or plug.
5.- To reduce the risk of electric shock, unplug the charger from the outlet before
attempting any maintenance or cleaning. The use of any non-recommended accessory
may result in a risk of fire, electric shock, or personal injury.
IMPORTANT
If you experience any problems with the operation of your Talkcom TC750, restart your device
turning it off and removing the batteries. Replace the batteries with another set and turn on the
device again. Verify that the batteries are charged, since in many cases low batteries may cause
problems such as no transmission, weak signal reception or low volume.
