POWER UP SELF-TEST1.0 Error CodesTurning on the radio using the on/off volume control starts a self-test routine which checks the RAM,
ROM checksum, EEPROM hardware and EEPROM checksum. If these checks are successfully
completed, the radio will generate the Self-Test Pass Tone. If the self-test is not successful, a “bonk”
is heard. Radios with displays are able to display these error messages:•“RAM TST ERROR” for •“ROM CS ERROR” for •“EEPRM HW ERROR” for •“EEPRM CS ERROR” for 
NOTERadio...

CONTROLLER INFORMATION1.0 OverviewThis section provides a detailed theory of operation for the radio and its components.2.0 Radio Power DistributionFigure 4-1 illustrates the DC distribution throughout the radio board. A 7.5V battery (BATT 7.5V)
supplies power directly to the electronic on/off control as UNSWB+. When the radio is turned on,
MECH_SWB+ (on/off/volume control) will trigger the electronic on/off control(momentary-on path),
then SWB+ is distributed as shown in Figure 4-1. Vdda...

4-2Controller BoardWhen low battery level is detected by the microprocessor through both conditions above, it will store
the radio personality data to EEPROM before turning off.3.0 Controller Board3.1 GeneralThe controller board is the central interface between the various subsytems of the radio. It is
separated into digital and audio architectures. The digital portion consists of a special Motorola
microcontroller (HC11FL0). The audio power amplifier (Audio PA) and audio/signalling/filter/
companding IC...

Controller Board4-33.2 Digital ArchitectureMCU configuration
There is one common MCU architecture for low-tier as well as for the high-tier products. It covers the
Conventional and Trunking portables. An open architecture system with the new HC11FL0 as the
processor is used. Combinations of different size RAM, ROM and EEPROM are available for various
application software.

Time Keeping. The RTC...
