Y4GDR5810S-1Two Way Radio

Instruction Manual DR5500S/5510S/5600S/5610S/5800S/5810S DMR/FM Portable Radio Thank you for purchasing a COVALUE two‐way radio. This simple to use radio adopts the latest advances in technology, providing reliable communication in today’s demanding communication environment. Notice to the User: · Please read this instruction manual before operating this radio. · It’s prohibited to use the radio or charge it at any area with a potentially explosive atmosphere (where the air contains gas, dust and smog, etc.), as well as while taking on fuel, or while parking at a gasoline service station; or any area where radio communication is prohibited (such as a hospital or an airport.) · It’s prohibited to operate the radio without permission in areas where the government laws prohibit radio communication. · Please don't expose the radio to direct sunlight for a long time; Don't place the radio near any heating devices, either. · Please don't put the radio in extremely dusty, moist humid areas or unstable surfaces. · Only qualified personal, with proper tools and instruments are allowed to service and repair the radios, do not disassemble the radio by yourself to avoid damages. FCCWarning： Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Note: This equipment has been tested and found to comply with the limits for a Class ice, pursuant to part 15 of the FCC Rules. B digital dev 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 off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 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 . —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver . —Connect the equipment into an outlet on a circuit different 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. 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). Keep the radio unit at least 2.5 cm away from the face. Keeping the radio at the proper distance is important as RF exposure decreases with distance from the antenna. The antenna should be kept away from the face and eyes. When worn on the body, always place the radio in a COVALUE approved holder, holster, case, or body harness or by use of the correct clip for this product. Use of non-approved accessories may result in exposure levels which exceed the FCC's occupational/controlled environmental RF exposure limits. Use of non-approved antennas, batteries, and accessories causes the radio to exceed the FCC RF exposure guidelines. 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). Maintenez l'unité radio à au moins 2,5 cm du visage.Le maintien de la radio à la distance appropriée est important car l'exposition aux radiofréquences diminue avec la distance del'antenne. L'antenne doit être éloignée du visage et des yeux. Lorsqu'il est porté sur le corps, placez toujours la radio dans un support, un étui, un étui ou un harnais de sécurité approuvé par COVALUE ou utilisez le clip approprié pour ce produit. L'utilisation d'accessoires non approuvés peut engendrer des niveaux d'exposition supérieurs aux limites d'exposition aux RF professionnelles / environnementales contrôlées de la FCC. L'utilisation d'antenne…

This equipment meets the requirements of the FCC Rules, Parts 90.203(e) and (g), as applicable. Programming of this products transmit frequencies can be performed only by the manufacturer or by service or by maintenance personal. The operator can’t program transmit frequencies using the equipment’s external operation controls. This is to certify that the requirements of 47 CFR Part 90.203(j)(4) and (5) spectrum efficiency are met by the SHENZHEN COVALUE COMMUNICATIONS CO., LTD. as demonstrated by the tests conducted on the sample radio provided. The tests show that the 4FSK data rate is in accordance with ETSI TS 102 361-1, that is 9600 bits per second in a 12.5 kHz bandwidth to satisfy the data rate requirement of 4800 bits per second per 6.25 kHz of channel bandwidth (7K60F1D emissions). Additionally the Two way radio uses the AMBE+2 half-rate vocoder to compress 60 ms of normal bursts are sent in alternate 30 ms TDMA slots and so comply with the equivalence of one voice channel per 6.25 kHz bandwidth (7K60F1E emission). Additionally the radio also meets the requirement of one voice channel per 12.5 kHz of channel bandwidth for analogue speech (11k0F3E emission).
