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.
