DM8000/DM8100 QUICK START GUIDE DM8000 DM8100 2 8 8 Microphone Jack For voice communications, connect a 600 microphone equipped with an 10-pin modular plug into the modular socket on the front of the main unit. Press firmly on the plug until the locking tab clicks. (Figure 7) Figure 7 Figure 8 location that will not interfere with vehicle operation.(Figure 8) FCC Warning： Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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 . This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part Note: 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 radiate 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 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 o f 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 into an outlet on a circuit di ferent from that to which the receiver is connected . —Consult the dealer or an experienced radio / TV technician for help. ISEDC warning: NOTICE: This radio is intended for use in occupational/controlled conditions where users have full knowledge of their exposure and can exercise control over their exposure to meet the occupational limits in FCC/ISEDC and International standards. This radio device is not authorized for general population consumer use. RF Exposure Requirements: . To control your exposure and ensure compliance with the occupational/controlled environmental exposure limits, always adhere to the following procedures. f f This equipment complies with FCC&ISEDC radiation exposure limits set forth for an controlled environment . This equipment should be installed and operated with minimum distance 40cm between the radiator& your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Guidelines: Do not remove the RF Exposure Label from the device. User awareness instructions should accompany device when transferred to other users. Do not use this device if the operational requirements described herein are not met. Operating Instructions: Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push-To-Talk (PTT) key. To receive calls, release the PTT key. Transmitting 50% of the time, or less, is important because the radio generates measurable RF energy only when transmitting (in terms of measuring for standards compliance). Respectez toujours les procédures suivantes pour contrôler votre exposition et vous assurer de la conformité avec les limites d'exposition professionnelle en milieu de travail / environnementales contrôlées. Des lignes directrices: Ne retirez pas l'étiquette d'exposition RF de l'appareil. Les instructions de sensibilisation des utilisateurs doivent accompagner l'appareil lors de son transfert à d'autres utilisateurs. N'utilisez pas cet appareil si les exigences opérationnelles décrites ici ne sont pas satisfaites.Mode d'emploi: Ne transmettez pas plus que le facteur de droit nominal de 50% du temps. Pour transmettre (parler), appuyez sur la touche Push-To-Talk (PTT). Pour recevoir des appels, relâchez la touche PTT. La transmission de 50% du temps, ou moins, est importante car la radio génère une énergie RF mesurable uniquement lors de la transmission (en termes de mesure pour la conformité aux normes). The maximum antenna gain is 0dBi for UHF. L'utilisation d'antennes, de piles et d'accessoires non approuvés a pour conséquence que la radio dépasse les consignes d'exposition RF de la FCC/ISEDC. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This device complies with Innovation, Science and Economic Development Canada licence-exempt RSS standard (s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference,including interference that may cause undesired operation of the device. Tout changement ou modification non expressément approuvé par la partie responsable de la conformité pourrait annuler l'autorité de l'utilisateur à faire fonctionner l'équipement. Cet appareil est conforme aux normes RSS exemptes de licence d'Innovation, Sciences et Développement économique Canada. Le fonctionnement est soumis aux deux conditions suivantes : (1) cet appareil ne doit pas causer d'interférences, et (2) cet appareil doit accepter toute interférence, y compris les interférences pouvant entraîner un fonctionnement indésirable de l'appareil. L'appareil est conforme aux limites d'exposition aux rayonnements et isedc spécifiées pour les environnements contrôlés. Cet émetteur ne doit pas être colocalisé ou fonctionner de concert avec une autre antenne ou un autre émetteur. Lors de l'installation et de l'utilisation de cet appareil, la distance minimale entre le radiateur et le corps doit être de cm. 40 FCC&ISEDC
