R-400A Telemetry Receiver Operating Manual NEW R-400A FEATURES COVERS THE ENTIRE 216.000 220.000MHz BAND IN 1kHz STEPS FOR QUICK AND ACCURATE FREQUENCY SELECTION SUPER SELECTIVE 8 POLE SSB CRYSTAL FILTER FOR GREATER RANGE IN HIGHLY CONGESTED RF ENVIRONMENTS .
INTRODUCTION Congratulations on purchasing the new R-400A Telemetry Receiver. This receiver is an exceptional value for a synthesized receiver covering any frequency between 216.000 and 220.000MHz with no gaps in coverage. This not only allows you to hunt with multiple birds transmitting at the same time, but multiple dogs also. The R-400A is supplied with a folding high gain, and very directional antenna which mounts directly to the receiver and rivals a Yagi in performance.

1. ANTENNA JACK Industry standard BNC female antenna jack accommodates either the supplied directional antenna, standard coax lead with external yagi antenna, or auto rooftop antenna. Just push the plug into the jack and twist clockwise to lock into place. Twist counterclockwise and pull to remove. 2. METER The lighted meter is used to measure the relative strength of the incoming signal. Use the VOLUME CONTROL and RF GAIN SWITCH to set the meter in the center of the scale.
4. SPEAKER A large, full audio range speaker is used to provide very good sound quality. Keep liquids, dirt, sand, and other foreign material from falling into the small holes in the speaker grill. 5. ON-OFF-BATTERY TEST SWITCH In the OFF position, no battery current is drawn. This is how the switch should be left when the receiver is not in use. When switched to the ON position, the receiver is active and drawing current from the battery.
9. FREQUENCY SELECT SWITCHES The FREQUENCY SELECT SWITCHES control the frequency synthesizer in the R-400A so it operates on the selected frequency. The single digit pushwheel switch shows the MHz range selected. It will be a 6 for 216MHz, a 7 for 217MHz, an 8 for 218MHz, or a 9 for 219MHz. Any other number selected (0,1,2,3,4, or 5) will mute the R-400A so no audio can be heard from the speaker.
ANTENNA The R-400A is supplied with a high gain, directional antenna that attaches directly to the receiver. In order to find your birds direction, the antenna elements must be fully extended as shown below. You may change the polarity by rotating the receiver with your hand. The below photos show both vertical and horizontal polarization. Hold the R-400A as shown in the photos and try both vertical and horizontal polarization while turning your body around in a circle.
To collapse the antenna elements, slide the Figure B numbered buttons shown in Figure B. Start with position 1 as you gently fold in the elements. Repeat for positions 2 through 4. When opening the antenna it does not matter which order the elements are unfolded. Release Button Dovetail Base The directional antenna can be used in two ways.
USING TELEMETRY TO FIND YOUR BIRD OR DOG 1. Install a working transmitter with a known good battery or batteries on your bird or dog. 2. Momentarily put the ON-OFF-BATTERY TEST SWITCH on the R-400A in the BATTERY TEST position and see if the battery tests O.K. on the meter. If questionable, be sure to carry a spare with you. 3. Unfold the FA-3 directional antenna. Turn the ON-OFF-BATTERY TEST SWITCH to ON and set the VOLUME CONTROL to a comfortable listening level. 4.

TROUBLESHOOTING The R-400A sounds different than it used to: -Test battery and replace if the needle is below 8 on the meter. (see page 4) There is no audio coming from the speaker: -Make sure the MHz frequency switch is set to 6,7,8 or 9. (see page 6) Unable to hear signal from transmitter: -Set the RF Gain Control to the high position, fully clockwise. (see page 4) FCC COMPLIANCE INFORMATION This device complies with Part 15 of the FCC rules.
