The Third-Party Application Notice

Please read all warnings carefully before using the radio:

• Do not use the radio equipment for different uses other than those indicated in this Guide.

• For the correct use of the radio read what is listed in the relative User Guide firstly.

• Protect the radio from the spray of water and/or other liquids and from dust.

• Do not bring the radio close to heat sources.

• Do not place the portable radio above the airbags or in their area of action. If the airbag is activated, it may not swell correctly and/or hurl the portable unit with great force, inside the compartment where are located the passengers.

• Protecting the external antenna connector with proper cover when it isn’t used in normal operative conditions.

• It is advisable to cover the connector when it isn’t used in normal operative conditions.

• Replace the batteries with equivalent, which are approved by the manufacturer.

• Replace the batteries following the instructions given in the technical manual.

• Make sure that batteries aren’t damaged and don’t have liquid leaks or evident gaseous emissions.

• Do not use the radio if the battery is damaged.

• Put the battery charger far from heat resources and in such a way as to guarantee its correct aeration as well as safe accessibility to the network power supply outlet. Do not
  use the battery charger outside of the environments for which it was specified (eg. external environment).

• Use only battery chargers recommended by the manufacturer and follow the instructions described in the user manual to recharge the battery.

• Do not use the radio if the antenna is damaged.

• Turn off the radio or inhibit transmission, if the equipment allows it, in electromagnetically sensitive environments (ex. hospitals, airports, etc.).

• Electronic devices are sensitive to electromagnetic interference (EMI) if not adequately shielded, designed, or configured differently for electromagnetic fields immunity. If electromedical equipment (ex. pace-makers, acoustical equipment, etc.) is used together with the portable radio, make sure that it is adequately shielded from external electromagnetic fields.

• Carry out the maintenance operations on the portable radio following the instructions given in the technical manual.

• Follow all accident prevention standards when carrying out maintenance operations on the portable radio equipment and use the proper tools (spanners, screwdrivers, etc.).

• First and second-level maintenance operations on the equipment are to be carried out by authorized technicians only.

• Third maintenance level operations are to be carried out by CALCUTTA technicians only.

• Use only original accessories and spare parts, approved by the manufacturer, suitable for the radio. The use of different accessories and/or spare parts (earphones, antennas, etc.) makes the safety and electromagnetic compatibility certifications to be valid no more and it could lower the user safety level and/or generate electromagnetic fields that exceed the accepted limits.

• Follow the battery charger instructions in order to use it correctly.

• During voice calls, the radio use with its proper bag is not recommended in environments where the temperature can be over 45°C.

• The emergency call is a priority type call. The portable radio, like all mobile telephony equipment, operates with radio frequency signals, therefore, the forwarding of the call
  depends on the network coverage during the call.

• If you need to send an emergency call, keep pressing the emergency button for at least 2 seconds, when the radio is switched on.

• Do not cause short circuits between the battery terminals. Do not set the batteries on metal surfaces. Do not set metal tools on the battery terminals. Be careful when handling any battery, when placing it in a pocket, purse/bag, or any other.

• Do not use the battery charger if the power supply cable and/or the plug are damaged.

• If the battery is incorrectly replaced existing the dangerous risk of explosion.

• Even if the battery is discharged, the risk of explosion exists if the battery is disposed of on fire.

• Do not take the radio into environments that have a potentially explosive atmosphere (ex. fuel storage sites, filling stations, etc.). Even when it is off, the radio, being equipped with a battery, might casually generate sparks that could trigger fires and/or explosions.

• Do not use the battery charger in environments that have a potentially explosive atmosphere (ex. fuel storage sites, filling stations, etc.). The use of a battery charger might generate sparks that could trigger fires and/or explosions.

• In order to further increase the level of user safety, you have to observe the following precautions:

• The radio is equipped with an automatic system to control the power transmitted so that the radio transmits at the maximum power only in exceptional cases (radio coverage limit, emergency call). Avoid touching the antenna when the radio is on and especially during transmission because the ability to transmit power gets worse.

• During voice communications in earphones, mode holds the portable radio with the antenna straight and above your shoulder and speaks directly into the microphone.

• Hold the portable radio in the vertical position and always at least 2.5 cm away from your head during voice communications in loudspeaker mode.

COMPLIANCE WITH RF EXPOSURE STANDARDS

CALCUTTA two-way radio is designed and tested to comply with a number of national and international standards and guidelines for human exposure to radiofrequency electromagnetic energy.
This radio complies with the IEEE (FCC) and ICNIRP exposure limits for occupational/- controlled RF exposure environments at operating duty factors of up to 50% talk-50% listen and is authorized by the IEE/ICNIRP for occupational use only.
Control Guidelines:
User awareness instructions should accompany the device when transferred to other users.
Do not use this device if the operational requirements described herein are not met.
Operating Instructions:
Transmit no more than the rated duty factor of 50% of the time. To receive calls, release the PTT button. Transmitting 50% of the time, or less, is important because this radio generates measurable RF energy exposure only when transmitting(in terms of measuring for standards compliance).
Hold the radio in a vertical position in front of the face with the microphone (and other parts of the radio including the antenna) at least 2.5 cm (1 inch) away from the nose or
lips. The antenna should be kept away from the eye. Keeping the radio at a proper distance is important since RF exposures decrease as the distance from the antenna increases.
