Power on

Just apply 12 V power to the RED and BLACK connectors of the main controller. The buzzer emits a single long beep, the LED starts flashing at one second intervals and the right ascension motor begins rotating.

Monitoring

The power supply is monitored by the controller :

• When the power supply voltage is above 11.5 V, the LED flashes green.
• When it drops below 11.5 V, the buzzer emits a double beep, and the LED starts flashing amber.
• Finally, when it drops below 11 V, the buzzer emits again a double beep, and the LED starts flashing red... and the battery won't last long after that.

Tracking, guiding

The tracking rate of the right ascension motor can be set to Sidereal, Solar, Lunar, or User tracking rate, with the RATE switch.

Using the keypad North, South, East, West buttons, you can slew in the corresponding direction.
The slew speed is controlled by the FAST switch :

• at Off ("slow") position,

  • the right ascension motor slow or accelerate at 20% of the tracking rate,
  • the declination motor rotate at slow speed,

• at On ("fast") position, the right ascension and declination motors rotate at maximum speed.

Settings

The SETTINGS switch allows to change parameters, depending on the switch position :

• Position 1, "Normal" :
  • No parameter can be set, the system perform its operational function.
• Position 2, "Right ascension, slow" :
  • North or South button increments the power of the right ascension motor at tracking speed ; after maximum, the buzzer emits a short beep and the power reverts to its minimum value.
  • The rotation sense can be inverted by pressing North or South during more than one second.
  • East and West buttons decrement and increment the selected tracking speed by,
    • 1 % when the FAST switch is on,
    • 1 ‰ when the FAST switch is off.
• Position 3, "Right ascension, fast" :
  • North or South button increments the power of the right ascension motor at fast rate ; after maximum, the buzzer emits a short beep and the power reverts to its minimum value.
  • East and West buttons decrement and increment the fast rotation rate of the right ascension motor.
• Position 4, "Declination, slow" :
  • North or South button increments the power of the declination motor at slow speed ; after maximum, the buzzer emits a short beep and the power reverts to its minimum value.
  • East and West buttons decrement and increment the slow rotation rate of the declination motor.
• Position 5, "Declination, fast" :
  • North or South button increments the power of the declination motor at fast speed ; after maximum, the buzzer emits a short beep and the power reverts to its minimum value.
  • East and West buttons decrement and increment the fast rotation rate of the declination motor.

When a setting is changed, it is permanently saved after one minute without further modification.

Whatever the setting switch position, all settings can be reset to their factory value by pressing East and West buttons simultaneously during more than one second.

Easy isn't it ? Look, even my dog can use it ;o)
