Kenwood TS-890S Operation Manual - Page 5

BEFORE USING Precautions Please observe the following precautions to prevent fire, personal injury, and transceiver damage: ● Connect the transceiver only to a power source as described in this manual or as marked on the transceiver itself. ● Route all power cables safely. Ensure the power cables can neither be stepped upon nor pinched by items placed near or against the cables. Pay particular attention to locations near AC receptacles, AC outlet strips, and points of entry to the transceiver. ● Take care not to drop objects or spill liquid into the transceiver through enclosure openings. Metal objects, such as hairpins or needles, inserted into the transceiver may contact voltages resulting in serious electrical shocks. Never permit children to insert any objects into the transceiver. ● Do not attempt to defeat methods used for grounding and electrical polarization in the transceiver, particularly involving the power input cable. ● Adequately ground all outdoor antennas for this transceiver using approved methods. Grounding helps protect against voltage surges caused by lightning. It also reduces the chance of a build‑up of static charge.

This distance allows adequate clearance from the power lines if the support structure fails for any reason. ● Locate the transceiver so as not to interfere with its ventilation. Do not place books or other equipment on the transceiver that may impede the free movement of air. Allow a minimum of 10 cm (4 inches) between the rear of the transceiver and the wall or operating desk shelf. ● Do not use the transceiver near water or sources of moisture. For example, avoid use near a bathtub, sink, swimming pool, or in a damp basement or attic. ● The presence of an unusual odor or smoke is often a sign of trouble. Immediately turn the power OFF and remove the power cable. Contact a KENWOOD service station or your dealer for advice. ● Locate the transceiver away from heat sources such as a radiator, stove, amplifier or other devices that produce substantial amounts of heat. ● Do not use volatile solvents such as alcohol, paint thinner, gasoline, or benzene to clean the cabinet of the transceiver. Use only a clean cloth with warm water or a mild detergent. ● Disconnect the input power cable from the power source when the transceiver is not used for long periods of time. ● Remove the transceiver's enclosure only to do accessory installations described in this manual or accessory manuals. Follow provided instructions carefully, to avoid electrical shocks. If unfamiliar with this type of work, seek assistance from an experienced individual, or have a professional technician do the task. ● Enlist the services of qualified personnel in the following cases: a) The power supply or plug is damaged. b) Objects have fallen into or liquid has spilled into the transceiver. c) The transceiver has been exposed to rain. d) The transceiver is operating abnormally or performance has seriously degraded. e) The transceiver has been dropped or the enclosure damaged. ● Do not place the unit in excessively dusty and/or humid areas, nor on unstable surfaces. ● HF/ 50/ 70 MHz mobile antennas are larger and heavier than VHF/ UHF antennas. Therefore, use a strong and rigid mount to safely and securely install the HF/ 50/ 70 MHz mobile antenna. ● Do not put the plastic bag used for packing of this equipment on the place which reaches a small child's hand. It will become a cause of suffocation if it wears flatly. ● Turn the transceiver power off in the following locations: In explosive atmospheres (inflammable gas, dust particles, metallic powders, grain powders, etc.) About Liquid Crystal Display ● Brightness of the LCD screen may appear uneven and flickering may occur depending on the content displayed. This is not a malfunction. ● The LCD is manufactured using high-density technology to achieve more than 99.99 % of effective pixels. Less than 0.01 % of the pixels may not be lit or may remain lit all the time. This is not a malfunction. ● When using this product in a cold region or when the temperature of this unit or its surroundings is extremely low, it may take a few minutes for the LCD to reach the normal level of brightness after turning on the power. This is not a malfunction. When this occurs, turn off the power and allow the surrounding environment to reach the ambient temperature (10 ℃ to 30 ℃ or 32°F to 86°F) before using the unit. ● If you accidentally damaged the LCD display and the liquid in the LCD display splashes and gets into your eyes or mouth, rinse thoroughly with water immediately and seek medical attention. And if the liquid splashes on your clothes or skin, wipe off immediately with alcohol etc. Leaving it as is will harm your skin or damage your clothes. iii
