Battery Status LED Indicator The Power/Function LED on the top panel will mirror the keypad LED unless the programmable switch is set to Mute, and the switch is turned on. Alkaline, lithium or rechargeable batteries can be used to power the transmitter. The type of batteries in use are selectable in a menu on the LCD. When alkaline or lithium batteries are being used, the LED labeled BATT on the keypad glows green when the batteries are good. The color changes to red at a midpoint of the runtime. When the LED begins to blink red, there will be only a few minutes of operation remaining. The exact point at which the LEDs turn red will vary with battery brand and condition, temperature and power consumption. The LEDs are intended to simply catch your attention, not to be an exact indicator of remaining time. A weak battery will sometimes cause the Power LED to glow green immediately after the transmitter is turned on, but it will soon discharge to the point where it will turn red or the unit will turn off completely. Rechargeable batteries give little or no warning when they are depleted. If you wish to use these batteries in the transmitter, the most accurate way to determine runtime status is by testing the time provided by a particular battery brand and type, then using the BatTime function to determine remaining runtime. Belt Clips The wire belt clip may be removed by pulling the ends out of the holes in the sides of the case. Be sure to have a firm grip to avoid scratching the surface of the housing. An optional spring-loaded, hinged belt clip (model number BCSLEBN) is also available. This clip is attached by removing the plastic hole cap on the back of the housing and mounting the clip with the supplied screw. IR (infrared) Port The IR port is available on the top of the transmitter for quick setup using a receiver with this function available. IR Sync will transfer the settings for frequency from the receiver to the transmitter. Status LED Blue LED indicates ready status. Remote Function In the Setup Menu, choose to turn remote function on/off. The "dweedle tone" remote control is turned on or off with the Remote Menu, setting the transmitter to react to tones received (Enable) or to Ignore the tones. Setup... AutoOn? ProgSw Remote Remote Enable Ignore NOTE: Remote control of settings is enabled using a third party smart phone app named DCHTRemote, published by New Endian, LLC. www.lectrosonics.com 3 Battery Installation The transmitter is powered by two AA batteries. Lithium batteries are recommended for longest life. The battery status circuitry compensates for the difference in voltage drop between alkaline and lithium batteries across their usable life, so it's important to select the correct battery type in the menu. unit will not operate. The battery contacts can be cleaned with alcohol and a cotton swab, or a clean pencil eraser. Be sure not to leave any remnants of the cotton swab or eraser crumbs inside the compartment. Spring contacts Because rechargeable batteries run down quite abruptly, using the Power LED to verify battery status will not be reliable. However, it is possible to track battery status using the battery timer function available in the receiver. Push outward on the battery compartment door and lift it to open. Slide door outward, then lift up to open Insert the batteries according to the markings on the back of the housing. If the batteries are inserted incorrectly, the door will close but the Optional Battery Eliminator The transmitter can be powered by external DC using the optional LTBATELIM power supply adapter.

Also see receiver manual for scanning procedure. 5) Set encryption key type and sync with receiver (see pages 10 and 11). 6) Set programmable switch to desired function (see page 11). 7) Verify RF and audio signals are present at the receiver (see receiver manual). Xmit Menu Selecting Receiver Compatibility Mode The transmitter can be set to operate with different receivers: Duet: M2R digital IEM/IFB receiver DCH(X): M2R-X encrypted (FW v3.x) Input Menu Adjusting the Input Gain for Analog Inputs For analog gain adjustment, two multi-color LEDs on the top panel, one for each channel, provide a visual indication of the audio signal level entering the transmitter. The LEDs will glow either red or green to indicate modulation levels as shown in the following table. Signal Level CH1 Less than -20 dB Off -20 dB to +0 dB Green +0 dB and greater Red CH2 Off Green Green NOTE: This procedure is used for analog inputs only. AES digital input is factory set at the industry standard level. The LEDs on the top panel will glow blue when the audio level reaches about -40 FS. It is best to go through the following procedure with the transmitter in the standby mode so that no audio will enter the sound system or recorder during adjustment. 1) With fresh batteries in the transmitter, power the unit on in the standby mode (see previous section Powering On in Standby Mode). 2) Navigate to the Gain setup screen.

Always leave the transmitter gain adjustment set according to these instructions, and do not change it to adjust the audio output level of the receiver.

This feature enables a user to quickly find and listen to any of the performer's mixes on the stage. The mix includes the name, frequency, mixer settings and limiter settings. The mix is easily shared via the M2R IR port, added to the list of 16 mixes and stored until cleared by the user. The M2R allows the user to toggle between the mixes, making troubleshooting issues easy and efficient. The DCHT, DCHT/E01's M2R functions create an easy interface with the FlexList feature. The following options are available: SendAll Sync to send all available settings to the M2R transmitter via the IR port, including the performer's name, (or whatever name the user chooses for the DCHT, DCHT/ E01), frequency, mixer settings and limiter settings. NOTE: The SendAll function is designed for trouble shooting and allows for settings to be cloned to transfer to another receiver if there is a problem to be identified. Not all settings are available on the DCHT, DCHT/E01.

Once generated by the DCHT and transferred to an encryption capable receiver, the encryption key is available to be shared (synced) by the receiver with other encryption capable transmitters/receivers via the IR port. · Standard: Standard Keys are unique to the DCHT. The transmitter generates the Standard Key. The DCHT is the sole source of the Standard Key, and because of this, the DCHT may not receive (get) any Standard Keys. · Volatile: This one-time only key is the highest level of encryption security. The Volatile Key exists only as long as the power in both the DCHT Transmitter and an encryption capable receiver remains on during a single session. If the receiver is powered off, but the DCHT has remained turned on, the Volatile Key must be sent to the receiver again. If the power is turned off on the DCHT, the entire session concludes and a new Volatile Key must be generated by the transmitter and sent to the receiver via the IR port. MakeKey When the transmitter key type is set to Volatile, Standard or Shared, use this menu item to create a key that can be synced with an encryption capable receiver. WipeKey This menu item is only available if there is a Key Type currently on the DCHT that can be deleted. www.lectrosonics.com Select Yes to wipe the current key and enable the DCHT to create a new key.
