EXTERNAL SPEAKER When attaching an external speaker to the transceiver via the KCT-60, press the key programmed as [External Speaker] to output all received signals through the external speaker. The Press the [External Speaker] key again to output all received signals only through the built-in speaker. icon appears on the display. DISPLAY BRIGHTNESS You can cycle the display brightness between high, low, and off by pressing the key programmed as [LCD Brightness]. 17 BACKGROUND OPERATIONS TIME-OUT TIMER (TOT) The Time-out Timer prevents you from using a channel for an extended duration. If you continuously transmit for a preset time, the transceiver will stop transmitting and an alert tone will sound. Release the PTT switch. AUXILIARY PORT Press the key programmed as [AUX A] or [AUX B] to activate the auxiliary port. The auxiliary port is used with external devices. The The BUSY CHANNEL LOCKOUT (BCL) If BCL is set up by your dealer, you will be unable to transmit if the channel is already in use. icon appears on the display when the auxiliary A port is active. icon appears on the display when the auxiliary B port is active. BUSY appears on the display when you press the PTT switch. Use a different channel or wait until the channel becomes free. If your dealer has programmed BCL Override for your transceiver, you can override the BCL by pressing the PTT switch again, immediately after releasing it, when the channel is busy. CONTROL CHANNEL HUNT On digital Trunking channels, the transceiver automatically searches for a control channel. While searching for a control channel, the antenna icon will ash and no signals can be received. PTT ID PTT ID is the transceiver unique ID code which is sent each time the PTT switch is pressed and/or released. (PTT ID can be made only in analog operation.) COMPANDER If programmed by your dealer for a channel, the compander will remove excessive noise from transmitted signals, providing higher clarity of signals. (The compander is used only in analog operation.) Your dealer must set the compander for both the transmit side and the receive side in order for the compander to operate. TRANSMIT POWER Your dealer has programmed a transmit power level for each channel. Power levels can be high, medium (available only for NX-720H/ NX-720HG/ NX-820H/ NX-820HG), or low. 18 MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS Use only manufacturer or dealer supplied antennas. Antenna Minimum Safe Distance: cm ( inches), 50% duty Cycle. Antenna Gain: 0 dBd referenced to a dipole. The Federal Communications Commission has adopted a safety standard for human exposure to RF (Radio Frequency) energy which is below the OSHA (Occupational Safety and Health Act) limits. Antenna Mounting: The antenna supplied by the manufacturer or radio dealer must not be mounted at a location such that during radio transmission, any person or persons can come closer than the above indicated minimum safe distance to the antenna, i.e. 20 cm (8 inches) , 50% duty Cycle. To comply with current FCC RF Exposure limits, the antenna must be installed at or exceeding the minimum safe distance shown above, and in accordance with the requirements of the antenna manufacturer or supplier. Vehicle installation: The antenna can be mounted at the center of a vehicle metal roof or trunk lid, if the minimum safe distance is observed. Base Station Installation: The antenna should be fixed-mounted on an outdoor permanent structure. RF Exposure compliance must be addressed at the time of installation. Antenna substitution: Do not substitute any antenna for the one supplied or recommended by the manufacturer or radio dealer. You may be exposing person or persons to excess radio frequency radiation. You may contact your radio dealer or the manufacturer for further instructions. Maintain a separation distance from the antenna to person(s) of at least 20 cm (8 inches), 50% duty Cycle. This transmitter is authorized to operate with a maximum duty factor of 50%, in typical push-to-talk mode, for satisfying FCC RF exposure compliance requirements. You, as the qualified end-user of this radio device must control the exposure conditions of bystanders to ensure the minimum separation distance (above) is maintained between the antenna and nearby persons for satisfying RF Exposure compliance. The operation of this transmitter must satisfy the requirements of Occupational/Controlled Exposure Environment, for work-related use, transmit only when person(s) are at least the minimum distance from the properly installed, externally mounted antenna. Transmit only when people outside the vehicle are at least the recommended minimum lateral distance away from the antenna/vehicle. B59-0000-00
