8.8.3 ProVoice Digital Mode
ProVoice digital mode allows the radio to transmit and receive digitized voice signals. These digital
signals provide improved weak signal performance and they cannot be easily monitored with a standard
receiver. Groups and channels programmed for ProVoice digital operation transmit only digital signals.
Private calls cannot be received or transmitted when the radio is in ProVoice digital mode because the
radio does not know the cryptographic key used.
Message trunked group calls and individual calls will be answered back in the mode they were received,
assuming the call or hang time is still active. Individual, phone, all and emergency calls will be
transmitted clear if digital mode is disabled or inoperative.
• If receiving an analog message trunked call, the radio will respond in analog mode during the hang
time on the working channel.
• If receiving an analog I-Call, the radio will respond in analog mode during the hang time.
• When using the "WHC" feature to respond to an I-Call (after the hang time has expired), the call will
be transmitted in the mode defined by the system mode as programmed for the current system if the
ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call will be transmitted as
defined by the I-Call mode programmed in the list for that ID.
DTMF
The overdial and hot keypad features for transmitting DTMF tones are not available while in ProVoice
Digital Mode.
ERROR Messages
If any of the following error messages are displayed, the radio was either programmed incorrectly or
needs servicing:
DSP ERR
ERR=xxxx
DSP ERR
DIGV ERR
Power Up Only
If the ProVoice circuit board is not responding correctly, one of the following error messages will be
displayed and the radio needs servicing:
HARDWARE
ERR= 3X
3X will be a number between 30 and 38
8.8.4 ProVoice Private Mode
ProVoice private mode allows the radio to transmit encrypted messages and receive clear or private
transmissions. The radio will transmit private if the group/channel is programmed for private operation
and forced operation is pre-programmed.
If the radio was pre-programmed for auto-select, the radio will transmit in the following modes;
• If Private mode is enabled, transmissions are always in private mode.
