The Radio Hand Held Terminal features an illuminated display with adjustable contrast setting, and is shipped with a ten foot (10') coiled cord, as shown here. The Radio Hand Held Terminal is slightly over 7.5 inches in length.

The HHTr has two operational modes: Shared Mode and Master Mode.

Shared Mode
Operators can:

• Set individual radio volumes.
• Select multiple radios for "Receive-Only" monitor mode with visual activity indicators.
• Receive from & Transmit to one or more radios. Instant "hot-key" Rx/Tx activation is achieved by simply entering the radio's number.
• Radio Transmit "press-to-talk" for non-VOX radios supported.
• Adjust sidetone volume level.
• Toggle "Secure" and "Non-Secure" modes for individual radios.

Master Mode
In addition to those functions listed for the "Shared Mode," the operator can also:

• Set individual radio frequencies or assign Net numbers.
• Select individual radio squelch settings.
