Manual Initializtion
The SC4000 Radio Communicator may be manually restand /or initialized. The rest or reinitialization of the radio is performed by momentarily installing and removing a shorting plug on the JP6 CPU RST header. This procedure is performed on a radio that has been previously in service. This procedure will completely erase the programming that exsists in the CPU.
1. AC and /or DC is applied to the SC4000 and the radio is powered up.
2. Placing the shorting plug on pins 3 and 4 and leaving the shorting plug in place allows the CPU to be initialized.
3. Momentarily short pins 1 and 2 together.
4. This procedure will reset the CPU. The BAT OK LED will blink 3 times to indicate the CPU has been erased.
5. Remove the shorting plug from pins 3 and 4.
6. Short pins 1 and 2 together again and this will reinitialize the system.
