HVT Shipping Case

1. Make sure the antenna is connected to the transmitter.

2. Be sure to start each mission with a fully-charged battery pack.

See Charging the HVT battery pack (page 5). The RED LED blinks when the battery is low. If using alternative power source, connect through Ext. DC Power Source module supplied.

3. Select the Channel on the transmitter that matches the frequency and settings of your receiver or repeater receive Channel.

For programming instructions, see Programming on pages 10 to 15.

4. Unlock the Main Power Switch. Set the Main Power switch to LEFT for illumination, or RIGHT for camera TX only.

5. To operate the spotting laser, press the Laser ON/OFF Button. An LED in the button indicates ON/OFF State. The laser spots for approximately 30 feet, placing a dot in the center of the image. The laser produces a beam strength of less than 5 mW and is blink safe.

WARNING: Do not apply power to the transmitter unless an antenna or non-radiating load is connected to the Antenna SMA connector.

WARNING: Do NOT connect external DC power sources directly to the HVT. Connect all external DC sources through the supplied Ext. DC Power Source module. (Examples: car battery, customersupplied battery, etc.)

NOTE: Ensure the Zoom Retainer is plugged-in to the Monitor Zoom connector to ensure a 1:1 zoom setting. (See Page 7.) Otherwise, the zoom setting is not controled.

INTRODUCTION

The Handheld Video Transmitter

The Handheld Video Transmitter is the latest innovation in tactical video reconnaissance and digital video transmission from DTC. First responders will find the HVT valuable for search and rescue, assessing threats, physical security, and disaster sites. The HVT is an essential tool for government, military, and law enforcement teams.

Weighing only 5.5 pounds and completely portable, the HVT uses a Palladium digital transmitter and fits in a durable 9.8 by 9.0 by 4.8 inch package. Rechargeable Lithium batteries provide a nominal runtime of three hours with all features ON. Even longer runtimes are achieved with the illuminator LED’s and laser turned OFF. The LED’s are ultra-bright and efficient, providing sufficient illumination for excellent video in near total darkness.

A red spotting laser provides a safe method of effectively pointing the camera without the need for a monitor. The HVT was designed to go virtually anyplace and to work well in virtually any environment from sunlight to darkness. The HVT is the essential tool for tactical video collection and transmission. A miniature color video camera is fitted in the center of the HVT, with dual banks of illuminator LED’s in concentric circles around the camera.

Two types of LED’s are used with illumination beam-widths of 20 degrees and 45 degrees. This combination provides both a spot light and an effective flood light, with a combined output designed to recognize a person in a dark room at a 12-foot distance.

The HVT can be ordered to provide either NTSC or PAL video.
