These limits aredesigned to provide reasonable protection against harmful interference in aresidential installation. This equipment generates and can radiate radiofrequency energy. If not installed and used in accordance with theinstructions, it may cause harmful interference to radio communications.However, there is no guarantee that interference will not occur in aparticular installation. Verification of harmful interference by thisequipment to radio or television reception can be determined by turning itoff and then on. The user is encouraged to try to correct the interference byone or more of the following measures:2
lReorient or relocate the receiving antenna. Increase the separationbetween the equipment and receiver.lConnect the equipment into an outlet on a different circuit to that of thereceiver's outlet.lConsult the dealer or an experienced radio/TV technician for help.Operation is subject to the following two conditions:lThis device may not cause harmful interference.lThis device must accept any interference received, includinginterference that may cause undesired operation.Note: Changes or modifications to this unit not expressly approved by theparty responsible for compliance could void the user's authority to operatethe equipment.Compliance with RF Exposure StandardsHytera's radio complies with the following RF energy exposure standardsand guidelines:lUnited States Federal Communications Commission, Code of FederalRegulations; 47 CFR § 1.1307, 1.1310 and 2.1093lAmerican National Standards Institute (ANSI) / Institute of Electricaland Electronic Engineers (IEEE) C95. 1:2005; Canada RSS102 Issue 5March 2015lInstitute of Electrical and Electronic Engineers (IEEE) C95.1:2005EditionRF Exposure Compliance and ControlGuidelines and Operating InstructionsTo control your exposure and ensure compliance with theoccupational/controlled environmental exposure limits, always adhere to thefollowing procedures.Guidelines:lDo not remove the RF Exposure Label from the device.lUser awareness instructions should accompany device whentransferred to other users.lDo not use this device if the operational requirements described hereinare not met.Operating Instructions:lTransmit no more than the rated duty factor of 50% of the time. Totransmit (talk), press the Push-To-Talk (PTT) key. To receive calls,release the PTT key. Transmitting 50% of the time, or less, is importantbecause the radio generates measurable RF energy only whentransmitting (in terms of measuring for standards compliance).3
lKeep the radio unit at least 2.5 cm away from the face. Keeping theradio at the proper distance is important as RF exposure decreases withdistance from the antenna. The antenna should be kept away from theface and eyes.lWhen worn on the body, always place the radio in a Hytera-approvedholder, holster, case, or body harness or by use of the correct clip forthis product. Use of non-approved accessories may result in exposurelevels which exceed the FCC's occupational/controlled environmentalRF exposure limits.lUse of non-approved antennas, batteries, and accessories causes theradio to exceed the FCC RF exposure guidelines.lContact your local dealer for the product's optional accessories.ISEDC StatementThe device has been tested and complies with SAR limits, users can obtainCanadian information on RF exposure and compliance.Après examen de ce matériel aux conformité aux limites DAS et/ou auxlimites d’intensité de champ RF, les utilisateurs peuvent sur l’exposition auxradiofréquences et la conformité and compliance d’acquérir lesinformations correspondantesThis device complies with Industry Canada license-exempt RSS standard(s).Operation is subject to the following two conditions:lThis device may not cause harmful interference.lThis device must accept any interference received, includinginterference that may cause undesired operation.Le présent appareil est conforme aux CNR d'Industrie Canada applicablesaux appareils radio exempts de licence.
