It has up to 10 programmable channels for the RF transmission, accessed through a PC with DTC programming software installed. The transmitter is designed for personal protection and evidence gathering missions. Its miniature size and rugged design ensures safe concealment and longlasting performance. The frequency is programmable for narrowband (TIA/EIA 102 compliant) or wideband operation. These parameters may be saved in memory. The Derringer has a built-in internal microphone, the abilty to use an 36” external microphone, and built-in scrambler. Channel Programming Includes • Frequency • AGC (Automatic Gain Control) On/Off • Width (Narrow / Wide band) • Scrambled / Clear Signal ON/OFF .625 .2.140 .590 000 Note: Do not operate the transmitter without the noodle antenna installed. NOTE: To prevent unwanted interference keep the microphone and the noodle antenna separated. Do not allow them to come into contact with each other. QUICK START Using A Separate Microphone Install the noodle antenna into the antenna connector on the transmitter. Adjust length according to band of operating frequencies. Attach fresh batteries to the snap on connector. Using a small screwdriver, turn the recessed rotary switch located on the front cover to the desired channel. The configuration of each channel is managed with DTC programming software. The programming software included with your Derringer allows you to assign frequencies, and set the deviation. The NOODLE ANTENNA The “noodle” antenna may be adjusted over the frequency range of 138 MHz to 174 MHz by adjusting the amount of wire that is folded back along side the end of the antenna. Use heatshrink tubing to hold the adjusted length. The total length may be calculated by the following formula. Length (inches) = 2950 / (Freq MHz) PROCELL Install the 36” microphone into the microphone connector on the transmitter. DURCELL Example: CH1: 150.000 Center of operating frequency CH2: 151.000 CH3: 152.000 Length (inches) = 2950/151 Total length = 19.5" Length 2950 151 = 19.5 Loop TIPS PULL UP ON SECTION INDICATED TO RELEASE LOCK AND REMOVE Note: This is a push-on, pull off locking connector. The connector will rotate 360° in the transmitter without disconnecting. Use extreme caution when connecting or removing the noodle antenna. To remove pull the noodle antenna straight out. Battery Operation: Always remove battery when not in use. It is imperative to discard partially used batteries, as their remaining life is not predictable. Always start an operation with fresh batteries. Audio Circuit and Body Mounting Tips: All body-worn transmitters are susceptible to “clothing noise”. Reducing this rubbing effect is accomplished in a variety of ways. Secure the transmitter to the body with an ace bandage or a custom harness. Try to locate the microphone in an area where “pickup” will be best and rubbing noise is least. Avoid the arms, legs, crotch, under the arms or waist area. Front torso mounting is ideal. Always provide a small amount of strain relief on the micro phone cable itself. This reduces the noise caused by the microphone cable and element being tugged and prevents cable damage. Secure the microphone cable to the body with medical adhesive tape in at least two spots, the final being about an inch below the element. Remember to leave a strain relief loop! Completely cover the microphone element (facing outward) with an ordinary Band Aid™. This provides a damped baffle for the microphone and a slick surface for clothing to rub on, and actually does not impact audio pickup level at all. CONNECTIONS ANTENNA (Male MMCX Connector) This connector accepts the noodle antenna. Top View Microphone Multi Pin Connector MICROPHONE The Derringer uses an internal electret microphone in addition to an external microphone MULTI-PIN CONNECTOR (Male multi-pin connector) This connector mates with the 36” external microphone and also mates with the programming cable and optional vehicular power adaptor model VPA-2001. CHANNEL SELECT SWITCH (Rotary Switch) The channel select switch allows you to change transmit channels and is located on the front of the transmitter. It is a rotary switch which requires the use of the supplied screwdriver to turn the switching mechanism. Select a transmit channel number by turning the rotary switch. The configuration of each channel is managed with DTC programming software. The programming software included with your Derringer allows you to assign frequencies, set the deviation, turn ON/OFF scrambler mode, and turn ON/OFF AGC. Antenna Connector Front View Channel Select Switchable SPECIFICATIONS Front Cover View The Derringer measures just 2.1” by 1.1” by .4”; it provides ten user programmable channels and audio scrambling. Automatic gain control is programmable by channel as well. The Derringer contains an internal microphone, which is automatically disabled if an external microphone is attached. Power is provided by a convenient snap-on 9 Volt battery type connector. The back cover of the Derringer allows an individual to use a pencil to write down the frequency for each channel, as a quick reference guide. Back Cover View Note: Consider using a designator for your frequency, such as “A” or “Blue”. If you lose control of the transmitter you won’t compromise your frequency.

You may want to place a sticker over the rotary switch on the chassis so users in the field don’t attempt to change frequencies. This is often the best path for state and local agencies with limited frequencies available to them. DTC will also provide you with free software and a free programming cable, enabling you to change your transmit frequencies.This is ideal if you often work with other agencies, or anticipate the equipment being used by a multi-jurisdictional task force. You can program up to ten channel settings per unit. In general, this allows you to program most variations you might encounter in the field at the depot level. You will be able to program frequency, narrowband/wideband, AGC enabled/disabled and scrambler ON/OFF. As a practical matter, your Derringer transmitter’s frequencies will be dictated by the frequency of your receiver and/or repeater. In many cases, these devices are crystal controlled or have few channel options. TIP: Make sure that you program your transmitter to match the frequencies of your receiver, and test the components as a system prior to going into the field! 10 PROGRAMMING Installing DTC Universal Programming Software on your PC NOTE: Uninstall any previous versions by going to Add/ Remove Programs, clicking on DTC Universal Programming, and clicking on uninstall. 10 11 Click on Start, click on run.
