[. . . ] INSTRUCTION MANUAL FRS UHF FM TRANSCEIVER i4088A This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FOREWORD Thank you for purchasing the IC-4088A FRS FM transceiver. This FRS (Family Radio Service) FM transceiver meets the FCC regulation (FCC Part 95). This transceiver is designed for those who require top-grade quality, performance and outstanding reliability under the most demanding conditions. D FEATURES Free of user-license and applications Voice scrambler function for communication privacy External DC-IN jack for both operation and battery charging (Optional BC-149A or CP-18A is required) All 14 FRS channels are available Powerful 500 mW (ERP) high output power 38 convenient group channels I ATS (Automatic Transponder System) This convenient function automatically checks station availability within the operating range, and alerts you via function display indication. [. . . ] Recommended temperature range for charging: +50°F to +104°F (+10°C to +40°C) The optional BP-202 BATTERY PACK includes rechargeable Ni-Cd batteries and can be charged approx. Charge the battery pack before first operating the transceiver or when the battery pack becomes exhausted. If the battery pack seems to have no capacity even after being fully charged, completely discharge it by leaving the power ON all day. If the battery pack still does not retain a charge (or very little), a new battery pack must be purchased. At the end of its life, under various state and local laws, it may be illegal to dispose of this battery into the municipal waste stream. Call 1-800-822-8837 for battery recycling options in your area or contact your dealer. 5 3 BATTERY CHARGING I Charging connections D Regular charging with the BC-149A, CP-18A Connect the optional BC-149A AC ADAPTER or CP-18A CIGARETTE LIGHTER CABLE to [DC 6V]. 15 hours Optional CP-18A Cigarette lighter cable with DC-DC converter to cigarette lighter socket to [DC 6V] jack Optional BC-149A to AC outlet IMPORTANT!: Use the BC-149A or CP-18A ONLY. Other type of AC adapter, cigarette lighter cable or DC power cable with an external power supply may damage the transceiver. The optional BP-202 can only be charged-- other AA (R6) size rechargeable Ni-Cd cannot be charged. · When displayed channel stops at channel number "1, " a beep is emitted. · The selected channel is memorised when the transceiver is turned off. 4 9 5 RECEIVE AND TRANSMIT q Select the desired operating channel with [Y]/[Z]. When a signal is received: · " " indicator appears on the display. [Z] w Push and hold [PTT] to transmit then speak into the microphone. · Do not hold the transceiver too Appears close to your mouth or speak too loudly. · The transmit indicator " " appears on the display. e Release [PTT] to return to receive. IMPORTANT: To maximize the readability of the transmitted signal, pause a few sec. NOTE: The transceiver has an auto power save function to conserve the battery power. The power save function activates automatically when no signal is received for 5 sec. 10 RECEIVE AND TRANSMIT 5 Talk Range The IC-4088A is designed to maximize performance and improve transmission range in the field. However, the single most important factor in transmit range (talk power) is the surrounding environment. These radios are "line of sight" radios and as such, transmission range are influenced by the degree to which you can "see" the other communicating party. Large concrete structures and heavy foliage or transmission from inside a building or vehicle will reduce the talk power range. · Medium range: large buildings or trees blocking your line of sight. · Minimum range: mountainous areas or areas of heavy foliage. 5 11 I Setting the group code The IC-4088A is equipped with 38 group codes.
