  • Page 3 CAUTIONS AGAINST HIGH VOLTAGE Radio and radar devices are operated by high voltages of anywhere from a few hundred volts up to many hundreds of thousands of volts. Although there is no danger with normal use, it is very dangerous if contact is made with the internal parts of these devices. (Only specialists should attempt any maintenance, checking or adjusting.) There is a very high risk of death by even a few thousand volts, in some cases you can be fatally electrocuted by just a few hundred volts.
  • Page 4 First aid ☆Note points for first aid Unless there is impending danger leave the victim where he or she is, then begin artificial respiration. Once you begin artificial respiration, you must continue without losing rhythm. (1) Make contact with the victim cautiously, there is a risk that you may get electrocuted. (2) Switch off the machinery and then move the victim away slowly if you must.
  • Page 5 ☆If the victim has a pulse but is not breathing (“Mouth to mouth” resuscitation) Figure 1 (1) Place the victim’s head facing backward (place something under the neck like a pillow). (2) Point the chin upward to widen the trachea. (3) Pinch the victim’s nose, take a deep breath, then put your mouth over the victim’s mouth and exhale completely, making sure that your mouth completely covers the victim’s mouth.
  • Page 6 ☆If the victim has no pulse and is not breathing (Heart massage in combination with artificial respiration.) Figure 2 If the victim has no pulse, his or her pupils are dilated, and if you cannot detect a heartbeat, the heart may have stopped, beginning artificial respiration is critical.
  • Page 7 Before Operation Concerning the symbols This manual uses the following symbols to explain correct operation and to prevent injury or damage to property. The symbols and descriptions are as follows. Understand them before proceeding with this manual. WARNING Indicates a warning that, if ignored, may result in serious injury or even death.
  • Page 8 Handling precaution CAUTION Do not distribute this INSTALLATION MANUAL to ordinary users, because it has been created and published only for use by our service engineers. Do not use this equipment for anything other than specified. Doing so may cause failure or malfunction. Do not turn the trimmer resistors or the trimmer capacitors on the PCB unit, except when and if they need to be adjusted.
  • Page 9 CAUTION Locate the antenna tuner, TX antenna and lead-in wire in locations as far as possible from people and surrounding structures to satisfy the following conditions. • Far at least 30cm beyond anyone’s reach. • Low vibration. • Good ventilation and drainage. •...
