DESCRIPTION
The IPE Series radio is a synthesized, microprocessorbased, high performance portable FM radio designed for
EDACS systems. The lightweight radio provides reliable
communications operation in Enhanced Digital Access
Communications System (EDACS) trunking environments.
Dispatch features such as group calls, individual calls,
agency/fleet calls, etc. are offered. Duplex interconnect is
also provided in EDACS trunked environments while
operating in the Telephone Interconnect Mode.
The radio is manufactured with advanced state-of-theart technology and designed with a minimum of serviceable
parts. It is not practical to service the radio to component
level (in the field). Technicians servicing this radio sho uld
only be concerned with isolating a problem to software or
hardware. Repair is limited to reloading software or
replacing the circuit board. There are no alignments or
adjustments to be made. This manual provides the
instructions for:
• • basic radio operation
• • programming the radio personality and flash code
• • isolating a problem to hardware or software
• • disassembling the radio and replacing the circuit
board

PC PROGRAMMABLE FEATURES
RADIO FEATURES
The lightweight (12 oz) radio provides cellular-like
duplex interconnect with the power and efficiency of
EDACS trunking. The radio takes advantage of EDACS
Infinity battery technology and provides up to 16 hours of
standby on a single charge. The IPE offers all the duplex
interconnect features in a cellular telephone including:
• full duplex interconnect
• familiar telephone - style keypad
• 25-number call list
• last number redial for fast, effortless use
• call length timer
• two-line, 10-character alphanumeric display that's
backlit for nighttime use
6
The radio is PC Programmable, which allows the radio
to be customized or upgraded quickly and easily. All PC
programmable functions are controlled by the
microprocessor and are field programmable using the
EDACS-2 PC Programmer and a compatible DOS based
PC. The programmable parameters are stored in a EPROM
and accessed by the microprocessor as needed. Refer to the
EDACS-2 PC Programming manual for detailed
programming instructions.
