Install the battery

1. Use a CR2032 lithium 3-volt cell. Marshall recommends the Renata CR2032.

2. Put the negative side down. After it is in, you should be able to read CR2032 and the plus sign on the top of the cell.

3. Insert it at an angle, toward the tab spring. Do not push it straight down. That can damage the springs. The transmitter starts as soon as the cell is in.

4. Screw the lid on as tight as you can with your fingers. A little more torque with pliers is fine. A loose lid can come off.

5. To take a cell out, turn the transmitter upside down and tap it gently.

How long the battery lasts

About 10 days of continuous transmission on a new battery. A double beep every 10 pulses warns you before it runs out. The transmitter tracks total transmission time and also checks voltage, so it warns you if you install an old battery.

Turn it on and off

If your Scout has a magnet, touch it to the battery lid. You will hear 5 fast beeps for off and 3 fast beeps for on. If you lose the magnet, unscrew the lid. Listen for the signal before you fly and after you switch it off.

Apollo 13 Mode

After 24 hours of continuous running, the pulses become shorter and more frequent: 20 milliseconds at 2200 pulses per minute. This is different from the very high frequency Scout, which slows its pulses. The faster beeps make a lost bird easier to hear in the following days.

Wash and inspect

1. The case is waterproof. Wash it with hot water. Dry the inside of the case and the lid before you install a battery.

2. Replace the antenna at the first crack or bare wire.

3. On a tail mount, inspect the tail spring.

4. On a leg mount, inspect the bewit slot for wear.

Replace the antenna

Use the Short and Safe ultra high frequency antenna, 6.5 inches. The replacement comes with instructions. Use only a genuine Marshall antenna with Power Line Static Protection.

1. Unscrew the antenna protector.

2. Unscrew the old antenna with your fingers.

3. Screw the new antenna on hand tight. A small bead of quick-drying epoxy at the base is fine.

4. Put the protector back on.

How it mounts on the bird

Match the photo to the hardware you ordered. The bird photos show the leg and tail methods. They use a GPS transmitter so you can see where the hardware sits.

Point the receiver

1. The signal from the Scout is strongest when the receiver antenna lines up with the transmitter antenna.

2. A bird on a perch holds its tail nearly straight up. Hold the receiver elements straight up.

3. A bird on the ground can leave the antenna nearly flat. Turn the elements flat and listen again.

4. If you can hear the signal both ways, use the flat position to pinpoint the bird.

Warranty

Marshall Radio Telemetry warrants that the Scout ultra high frequency transmitter will be free from defects of workmanship and materials for one (1) year from the date of purchase by the end user. Return a defective transmitter directly to Marshall Radio Telemetry and we will repair or replace it and return it free of charge. Damage from misuse or normal wear and tear is not covered, and the warranty is void if a non-Marshall antenna has been used. Marshall Radio is not responsible for damages or loss beyond the value of the transmitter itself, including but not limited to the loss of a bird or lost time.
