Dual-Tone Multi-Frequency: Overdial/Conventional Mode

Once the radio has established a connection to the public telephone system, it

may be necessary to “over-dial” more digits to access banking services,

answering machines, credit card calls, or other types of systems that require

Dual-Tone Multi-Frequency (DTMF) access digits.

Overdial operation can also be used to initiate a telephone interconnect call

via DTMF signalling if a dial tone has already been accessed on the system.

This method makes a telephone interconnect call while operating in the

conventional mode but will also function in trunked mode if a dial tone is

directly accessible.

Telephone numbers and other number sequences for overdialing can be stored

in the phone list when programming the radio. These numbers are accessed

by pressing

, then following the selection mode rules. The following steps

are required to dial these numbers:
