INTRODUCTION TO AMATEUR RADIO Your transceiver is the perfect first radio for anyone entering the exciting world of amateur radio, as well as a great additional transceiver for the experienced amateur radio operator. Your transceiver opens a door for you to the world from almost any- where! All you need is an Amateur Radio Operator’s License (Technician Class or higher) issued by the Federal Communica- tions Commission (FCC).
Volunteer Examiner Team. Contact the ARRL for a schedule of exam op- portunities in your area. The Technician Class license lets you use the HTX-200 to com- municate directly with other operators, and use repeaters for dis- tant communication.
PREPARATION POWER SOURCES You can operate your transceiver from any of three power sourc- • internal batteries • AC power (using an optional power supply and DC adapter) • vehicle battery power (using an optional DC adapter) Using Internal Batteries Your transceiver can use two AA batteries (not supplied) for pow- er.
4. Replace the cover and slide the cover. Testing Internal Batteries When you turn on the HTX-200, BAT appears briefly and the graduated bar (the signal strentgth meter) next to BAT indicates the battery strength. If the batteries are weak, the graduated bar shows less than 4 boxes.
USING AC POWER You can operate the HTX-200 from AC power using a regulated power supply capable of supplying 13.8 VDC at least 1A and a vehicle power adapter (see “Using Vehicle Battery Power” on Page 12). The supply should also have an accessory power socket into which the DC-to-DC power adapter fits.
USING VEHICLE BATTERY POWER You can power the HTX-200 from a vehicle’s 12V power source (such as cigarette-lighter socket) using an 9-volt, 900 mA DC-to- DC power adapter and a size I Adaptaplug with TIP set to +. Both are available at your local RadioShack store.
. Turn it clockwise to remove it. Caution: Do not over-tighten the antenna Note: You can connect an external antenna to the HTX-200 using an SMA-to-BNC adapter. This adapter, as well as suitable anten- nas, are available through your local RadioShack store.
ATTACHING THE WRIST STRAP To attach the supplied wrist strap to the top of the belt clip, thread the strap’s small loop through the opening in the top of the clip. Then insert the longer loop through the smaller loop and pull on the strap until the loop is tight.
Caution: Use only microphone and speaker accessories that do not share a common ground for the speaker and the microphone. Doing otherwise might damage the transceiver. Note: Inserting a headset’s plug automatically disconnects the in- ternal speaker. You can also connect an optional mono earphone to the SPK jack.
