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. 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.
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. The battery contacts can be cleaned with alcohol and a cotton swab, or a clean pencil eraser.

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).
5) Turn the recorder or sound system gain down before setting the transmitter to the normal operating mode and enabling the audio output. 6) If the audio output level of the receiver is too high or low, use only the controls on the receiver to make adjustments. 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. Selecting Input Type AES digital or analog audio input is selected with the InType menu item.
M2R Menu Selecting M2R Receiver Functions The M2R Receiver includes a FlexList™ mode where up to 16 mixes can be accessed by name. 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.
• Shared: There are an unlimited number of shared keys available. 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.
