User's Manual

Digi-Wave 400 Series Digital Transceiver

PRELIMINARY MANUAL

Side Tone Adjustment

This gives the user the ability to change the volume of their own voice as heard in the headset (side tone). This feature is only

available on the DLT Transceiver. Use the up and down arrow buttons to choose between o (0 dB), low (-6 dB), or high (-12 dB).

Microphone Gain and Line Gain

Gain can be used to increase the volume of the microphone or input sound. Use the up and down arrows to adjust the gain to a

suitable level.

Encryption

Extra security can be added to the transmitted signal via encryption. An 87-bit encryption is default, and this level of encryption

is backwards compatible with the DLT 300 or DLR 360 from the previous generation.

127 + 87-bit Encryption adds AES-128 encryption on top of the 87-bit encryption. This adds an additional layer of security, but is

not backwards compatible and may only be used with Digi-Wave 400 devices.

Encryption can also be turned completely o, if desired, which will leave no security features. This is not recommended.

DLT Secure PIN:

When a group or channel has been set up with a secure PIN, transceivers and receivers

without this secure PIN entered cannot listen in on the group. The same four digit code must

be programmed into all of the Digi-Wave devices in the group. As the PIN is being entered,

individual numbers will be replaced by the * symbol.

Interpretation Modes

Standard Interpretation Mode

Standard interpretation mode allows for each DLT Transceiver to listen to the ﬂoor (the main speaker) on channel 0 and

broadcast out in one interpreted language on a channel (1-14). Each additional channel or language requires their own DLT

Transceiver and interpreter. The audience member then listens to the channel for their speciﬁc language.

Bilingual Mode

Bilingual mode allows the interpreter to quickly switch their output channel between

Ch. 1 or Ch. 2, depending on which language the audience needs to hear. The DLT

transceiver in Bilingual Mode always listens to channel 0, regardless if channel 1 or 2 is

chosen as the transmission channel.

Relay Mode

Relay Mode allows the interpreter to quickly switch between listening to the Floor on

Channel 0 or the Relay on Channel 1. Channel 1 will automatically listen to Channel 0. Interpreters on other channels (2-14) are

able to switch which channel they are listening to.
