Operation issubject to the following two conditions : (1) this device does notcause harmful interference, and (2) this radio must accept anyinterference that may cause undesired operation.To maintain compliance with FCC’s RF exposure guidelines, forbody-worn operation, this radio has been tested and meets theFCC RF exposure guidelines when used with Midland RadioCorp. accessories supplied or designated for this product. Use ofother accessories may not ensure compliance with FCC RFexposure guidelines. IMPORTANT NOTICE, FCC LICENSE REQUIRED FOR GMRS OPERATION(Only Applicable for GMRS Radio Use in the United States)The LXT500/535 Series operates on GMRS (General Mobile Radio Service)frequencies which require an FCC (Federal Communications Commission)license. You must be licensed prior to operating on channels 1 - 7 or 15 - 22,which comprise the GMRS channels of the LXT500/535 Series. Seriouspenalties could result for unlicensed use of GMRS channels, in violation of FCCrules, as stipulated in the Communications Acts Sections 501 and 502(amended).You will be issued a call sign by the FCC which should be used for stationidentification when operating the radio on GMRS channels. You should alsocooperate by engaging in permissible transmissions only, avoiding channelinterference with other GMRS users, and being prudent with the length of theirtransmission time.To obtain a license or ask questions about the license application, contact theFCC at 1-888-CALL FCC or go to the FCC's website: http://www .fcc.gov and request form 605 . Exposure To Radio Frequency EnergyYour Midland radio is designed to comply with the following national andinternational standards and guidelines regarding exposure of human being toradio frequency electromagnetic energy:- United States Federal Communications Commission, Code of Federal Regulations: 47 CFR part 2 sub-part J - American National Standards Institute (ANSI)/Institute of Electrical & Electronic Engineers (IEEE) C95. 1-1992 - Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1999 Edition- National Council on Radiation Protection and Measurements (NCRP) of the United States, Report 86, 1986 - International Commission on Non-lonizing Radiation Protection (ICNIRP) 1998 To control your exposure and ensure compliance with the general population oruncontrolled environment exposure limits, transmit no more than 50% of thetime. The radio generates measurable RF energy exposure only whentransmitting. IMPORTANT: Changes or modifications to this unit not expressly approved by MIDLAND RADIO CORP. could void your right to operate this unit. Your radio is set up to transmit a regulated signal on an assigned frequency. It is againstthe law to alter or adjust the settings inside the COMMUNICATOR to exceedthose limitations. Any adjustment to your radio must be made by qualifiedtechnicians. LCD DISPLA Y 1. LOW BATTERY ICON – Indicates the battery level is low. 2.

The belt clip should be removedto ease installation or removal of the batteries. To install the batteries:1. With the back of the radio facing you, remove the belt clip (see diagram below) for easy access, then remove the Battery Cover by pressing down on the top center and sliding it down from the radio. 2. Insert 4 AAA batteries observing the polarity as shown. Installing the batteries incorrectly will prevent the unit from operating or may damage the unit. 3. Return the Battery Cover by sliding it up on the radio. Replace the belt clip, making sure it locks into place. 15 MM II DD LL AA NN DD RR AA DD II OO CC OO RR PP OO RR AA TT II OO NN 5900 Parretta Drive Kansas City, MO 64120 Call 816.241.8500 visit us at ht tp://www .midlandr adio .com Note: Features & Specifications are subject to change withoutnotice.

Held to face position For held to face position the flat section of a SAM Phantom or a flat phantom is used. The center of the radiating structure is to set on the middle position of the flat phantom. The distance between sample and flat phantom is 1.5 cm. For the measurement head tissue simulating liquid is used. Belt Clip/Holster Configuration Test configurations for body-worn operated EUTs are carried out while the belt-clip and/or holster is attached to the EUT and placed against a flat phantom in a regular configuration. An EUT with a headset output it tested with a headset connected to the device. Body dielectric parameters are used. There are two categories for accessories for body-worn operation configurations: 1.accessories not containing metallic components 2.accessories containing metallic components. When the EUT is equipped with accessories not containing metallic components the tests are done with the accessory that dictates the closest spacing to the body. For accessories containing metallic parts a test with each one is implemented. If the multiple accessories share an identical metallic component (e.g. the same metallic belt-clip used with different holsters with no other metallic components) only the accessory that has the closest spacing to the body is tested. In case that a EUT authorized to be body-worn is not supplied or has no options to be operated with any accessories, a test configuration where a separation distance between the back of the device and the flat phantom is used. All test position spacings are documented. Transmitters operating in front of a person’s face (e.g. push-to-talk configurations) are tested for SAR compliance with the front of the device positioned to face the flat platform. SAR Compliance tests for shoulder, waist or chest-worn transmitters are carried out with the accessories including headsets and microphones attached to the device and placed against a flat phantom in a regular configuration. The SAR measurements are performed to investigate the worst-case positioning. This is documented and used to perform Body SAR testing. [2]. Body tissue simulating liquid is used. Report File No. : F690501/RF-SAR001977 Date of Issue :2012-02-01 Page :5 / 64 1.7 EVALUATION PROCEDURES - Power Reference Measurement Procedures The Power Reference Measurement and Power Drift Measurements are for monitoring the power drift of the device under test in the batch process. The Minimum distance of probe sensors to surface determines the closest measurement point to phantom surface. The minimum distance of probe sensors to surface is 4㎜. This distance cannot be smaller than the Distance of sensor calibration points to probe tip as defined in the probe proper…
