6 SD- MOTOR FOR MODE CONTROL • Power voltage is dc 4.5 V and fed with regulated dc power
supply from battery terminal.
• Voltages are dc with respect to ground under no-signal
M902 (detuned) conditions.
M (SLED MOTOR)
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.
