*Note:

Use R1001 only with Ver.3.0 of microprocessor (IC801). Using R1001 with other micro- processor versions will cause operating errors so be sure to remove it.

You can check the version with Test Mode (page 7).

• Power voltage is dc 1.5V and fed with regulated dc power

 

 

 

 

supply from battery terminal.

 

 

 

 

 

• Voltages and waveforms are dc with respect to ground

 

 

 

 

under no-signal conditions.

• Voltages are taken with a VOM (Input impedance 10 MΩ).

 

 

 

 

Voltage variations may be noted due to normal produc-

 

 

 

 

tion tolerances.

 

 

 

 

 

Waveforms are taken with a oscilloscope.

 

 

 

 

Voltage variations may be noted due to normal produc-
