Thoseinstalling this article, on or within a specific type or classof aircraft, are responsible for determining that the aircraftinstallation conditions are suitable for the TSO article.TSO articles must have separate approval for installationin an aircraft. The article may be installed only if performedunder 14 CFR part 43 or the applicable airworthinessrequirements.NEVER bend the cables sharply or place the cables too nearthe aircraft control cables.DO NOT place the transceiver where hot or cold air blowsdirectly on it.AVOID placing the transceiver in areas with temperaturesbelow –20˚C or above +55˚C (–4˚F to +131˚F).NEVER connect the transceiver to a power sourceusing reverse polarity. Reverse polarity will damage thetransceiver.To prevent voltage drops, solder or crimp the cable lugwhen connecting the DC power cable to the power supply.Use a 50 Ω, vertically polarized, VHF air band antenna.VSWR should be less than 2.5:1.Mount the antenna on a flat metal surface or install a groundplane of at least 120 cm2 (18 in2).n PRECAUTIONS
