Park Position Rules
The Paramount must be homed before the mount is parked and before the park position can be defied
using the Set Park Position command. Otherwise, the mount will not return to the correct park position.
See TheSky Professional User Guide for more information about telescope parking.
Audible Control System Feedback
Each time the mount is turned on the control system performs both an electronics and servomotor
initialization, and emits different sounds based on the status of these initializations. A short whistle is
emitted immediately after the power switch is turned on and indicates successful initialization of the
control system electronics; two successive beeps (usually occurring a few seconds or so apart) indicate
successful motor initialization. The three Status LEDs on the Electronics Box, labeled TCS, HA, and Dec,
provide additional visual feedback of mount initialization. See “Electronics Box Components” on page 67
for details.
The initialization procedure is terminated if the joystick button on the hand paddle is pressed and held
down when the mount is turned on, or the joystick is moved from the center position before the
servomotor initialization is complete. In this situation, the mount emits a single beep. When initialization
is interrupted for any reason, the mount will not slew or track. Before attempting to slew or home the
mount, make sure the joystick is in the center position, power the mount off then on, and then wait for
the two beeps that indicate the mount is ready for normal operation.
The table below describes the different sounds the mount may emit, when in the startup process each
sound occurs, and describes what the sound means. To listen to each sound, visit the Software Bisque
website and click Support, Videos & Audio and search for “sounds” then click the Download graphic to
save the audio file to your computer.
For each axis, exactly when the beep
occurs depends on the angular distance
between the motor’s position when the
mount was powered on and the motor
index, or motor zero position. If both
motors happen to be initialized
simultaneously, you might hear only a
single beep.
