The Main Processor uses a “real time clock,” IC7, to keep time and store

important data while there is no power to the SG-2000. While power is applied

to the SG-2000, capacitor C31 charges to 5.5 volts. When power is removed,

capacitor C-31 will discharge through Q2. This keeps the battery power turned

on. After two weeks, the charge in C31 is reduced to the point that Q2 turns

off. This prevents the battery from fully discharging. This method of using a

battery and capacitor provides a much longer life span than a NiCad battery

and gives the same performance.

23.4.7

Operational Test

Remove the CPU from the Ports Test Board and replace IC16 with normal

software.

Connect the CPU through an extension cable to the SG-2000's head (for Head

CPU) or SG-2000's Exciter (for Main CPU).

Turn on the power at the head.

Verify that all keys operate and perform proper functions (consult other

sections of this manual for complete descriptions of proper functions.

Functions that should be checked:

Keeping a programmed time, date, channel and frequency on display for

30 seconds after the PS-30 has been turned off.

Alarm Generator

ON/OFF function from head

Program then erase a channel

C31 charging check (Main CPU only).

Place the Main CPU tested on the CPU charger for not less than 15 minutes.

Ten minutes after the Main CPU is removed from the charger, check that the

voltage across C31 is still no less than 5VDC.
