i PRECAUTIONS Please observe the following precautions to prevent fire, personal injury, and transceiver damage: ¥ When operating mobile, do not attempt to configure your transceiver while driving because it is simply too dangerous. ¥ Be aware of local laws pertaining to the use of headphones/headsets while driving on public roads. If in doubt, do not wear headphones while mobiling. ¥ Do not transmit with high output power for extended periods. The transceiver may overheat. ¥ Do not modify this transceiver unless instructed by this manual or by KENWOOD documentation. ¥ Do not expose the transceiver to long periods of direct sunlight nor place the transceiver close to heating appliances. ¥ Do not place the transceiver in excessively dusty areas, humid areas, wet areas, nor on unstable surfaces. ¥ If an abnormal odor or smoke is detected coming from the transceiver, turn OFF the power immediately. Contact a KENWOOD service station or your dealer. ¥ The transceiver is designed for a 13.8 V power source. Never use a 24 V battery to power the transceiver. NOTICES TO THE USER One or more of the following statements may be applicable: FCC WARNING This equipment generates or uses radio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in the instruction manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made. INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY THE FCC This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can generate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that the interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ¥ Reorient or relocate the receiving antenna. ¥ Increase the separation between the equipment and receiver. ¥ Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. ¥ Consult the dealer for technical assistance. When condensation occurs inside the transceiver: Condensation may occur inside the transceiver in such a case where the room is warmed using a heater on cold days or where the transceiver is quickly moved from a cold room to a warm room. When condensation occurs, the microcomputer and/or the transmit/receive circuits may become unstable, resulting in transceiver malfunction. If this happens, turn OFF the transceiver and just wait for a while. When the condensed droplets disappear, the transceiver will function normally.

21 4 TRANSMITTING 1To transmit, press and hold Mic [PTT] and speak into the microphone in a normal tone of voice. ¥ ÒON AIRÓ and the RF power meter appear. ¥ Speaking too close to the microphone, or too loudly, may increase distortion and reduce intelligibility of your signals at the receiving station. ¥ The RF power meter shows the relative transmit output power. 2When you finish speaking, release Mic [PTT]. Time-Out Timer: Holding down Mic [PTT] for more than 10 minutes causes the transceiver to generate a beep and stop transmitting. Release, then press Mic [PTT] to resume transmitting. You may change the time-out time to 3 or 5 minutes {page 70}. n Selecting Output Power ItÕs wise to select lower transmit power if communication is still reliable. This lowers the risk of interfering with others on the band. When operating from battery power, you will enjoy more operating time before a charge is necessary. Press [LOW] to select high (ÒHÓ), medium (ÒMÓ), or low (ÒLÓ) power. The default is high. ¥ You can program a different power for band A and B. u Do not transmit at high output power for an extended period of time. The transceiver could overheat and malfunction. u Continuous transmission causes the heat sink to overheat. Never touch the heat sink when it may be hot. Note: When the transceiver overheats because of ambient high temperature or continuous transmission, the protective circuit may function to lower transmit output power.

49 9 1Press [MNU] to enter Menu mode. 2Press [ c cc c c]/ [ d dd d d] to select ÒRADIO (1Ð)Ó, then press [OK]. 3Press [ c cc c c]/ [ d dd d d] to select ÒAUX (1Ð9Ð)Ó, then press [OK]. 4Press [ c cc c c]/ [ d dd d d] to select ÒSCAN RESUME (1Ð9Ð1)Ó, then press [OK]. 5Press [ c cc c c]/ [ d dd d d] to select Time-Operated (default), Carrier-Operated, or Seek. 6Press [OK] to complete the setting. 7Press [MNU] to exit Menu mode. SELECTING SCAN RESUME METHOD The transceiver stops scanning at a frequency (or memory channel) on which a signal is detected. It then continues scanning according to which resume mode you select. You can choose one of the following modes. The default is Time-operated mode. ¥Time-Operated mode The transceiver remains on a busy frequency (or memory channel) for approximately 5 seconds, and then continues to scan even if the signal is still present. ¥Carrier-Operated mode The transceiver remains on a busy frequency (or memory channel) until the signal drops out. There is a 2 second delay between signal drop-out and scan resumption. ¥Seek mode The transceiver remains on a busy frequency (or memory channel) even after the signal drops out and does not automatically resume scanning. Note: To temporarily stop scanning and monitor weak signals, press the Mic PF key assigned the Monitor function {page 62}. Press the PF key again to resume scanning.

74 16 WIRELESS REMOTE CONTROL (U.S.A./ CANADA ONLY) If you also have a compatible KENWOOD handy transceiver, you may use it as a remote control for this mobile transceiver. You will control one band on the mobile while sending DTMF tones to the other band from the handheld. This function will be useful, for example, when you want to control the mobile from a location outside your vehicle. Note: u As a remote control, you can also use a handy transceiver which does not have a remote control function but a DTMF function. You, however, must manually send DTMF tones for control code strings. Skip steps 1 and 3 in ÒPREPARATIONÓ. u The FCC rules permit you to send control codes only on the 440 MHz band. PREPARATION Let us assume band A (VHF) of the mobile transceiver will be controlled. On the handy transceiver: 1Program a 3-digit secret number. ¥ For the programming method, see the instruction manual for the handheld. ¥ If using a TH-D7A, see ÒWIRELESS REMOTE CONTROLÓ on its instruction manual. 2Select the transmit frequency on the UHF band. 3Make the handheld enter Remote Control mode. ¥ For the method, see the instruction manual for the handheld. If not described, consult your dealer. On the mobile transceiver: 4Access Menu 1ÐAÐ1 (CODE), and select the same secret number as you selected in step 1. ¥ Turn the Tuning control to select each digit. Press [ a aa a a] (or [ b bb b b]) to move the cursor to the next (or previous) digit. ¥ You can also press Mic [0] to [9] in sequence to enter 3 digits. DTMF tones
