SERVICE MANUALSTesting, alignment and service information are provided in the servicemanual for this model. Service manuals for Titan™ radios areavailable from Midland Radio Corporation at the address shown onthe back cover.7DO NOT transmit more than 50% of total radio use time (50% dutycycle). Transmitting for more than 50% of the time can cause FCCRF exposure compliance requirements to be exceeded. This radio istransmitting whenever the TX icon is displayed on the LCD. Pressingthe PTT switch on the side of the microphone normally causes theradio to transmit. Note: The preceding information is provided to make youaware of RF exposure and how to ensure that this radio isoperated within FCC RF exposure limits.You, as the qualified end-user of this radio device must control theexposure conditions of bystanders to ensure the minimum separationdistance, stated above for satisfying FCC RF exposure compliance, ismaintained between the antenna and nearby persons. Transmit onlywhen all person(s) are at least the minimum distance from theproperly installed, externally mounted antenna.IMPORTANT SAFETY INFORMATIONCAUTIONSa The antenna connector must be snugly tightened to maintainproper electrical connection and moisture resistance.a Equipment must be grounded according to Midland RadioCorporation installation instructions for safe operation.a Equipment should be serviced only by a qualified technician.a Refer to radio service manual for additional information oninstallation and safety precautions.WARNING!! DO NOT allow the antenna to touch or come in very closeproximity with the eyes, face, or any exposed body parts while theradio is transmitting! DO NOT operate the radio in explosive or flammableatmospheres. The transmitted radio energy could trigger blastingcaps or cause an explosion.! DO NOT allow children to operate or play with this radio. Note: The above warning list is not intended to include allhazards that may be encountered when using this radio.ii
