One-Year Limited Warranty
This Orion EQ3M Dual-Axis DC Motor Drive System is warranted against defects in materials or work-
manship for a period of one year from the date of purchase. This warranty is for the benefit of the original
retail purchaser only. During this warranty period Orion Telescopes & Binoculars will repair or replace, at
Orion’s option, any warranted instrument that proves to be defective, provided it is returned postage paid
to: Orion Warranty Repair, 89 Hangar Way, Watsonville, CA 95076. If the product is not registered, proof
of purchase (such as a copy of the original invoice) is required.
This warranty does not apply if, in Orion’s judgment, the instrument has been abused, mishandled, or
modified, nor does it apply to normal wear and tear. This warranty gives you specific legal rights, and you
may also have other rights, which vary from state to state. For further warranty service information, con-
tact: Customer Service Department, Orion Telescopes & Binoculars, 89 Hangar Way, Watsonville, CA

slow-motion control cables when the motors are engaged or
you could permanently damage the motors.
There are four pushbuttons on the hand controller. When the
motors are engaged the left and right buttons move the
mount about its R.A. axis, and the up and down buttons
move the mount about its Dec. axis. The rate of speed the
mount moves at is determined by the rate switch at the top
right of the hand controller. If the switch is at the 2x position,
the mount will move at two times the sidereal rate when any
of the buttons are pushed. Similarly, if the switch is at the 4x
or 8x position, the mount will move at four times or eight
times sidereal when a button is pushed. If no buttons are
pushed, the R.A. motor will turn the R.A. axis at sidereal rate
to track the motion of the night sky.
The 2x sidereal rate is the best setting for making guiding
corrections during long-exposure astrophotography. The 4x
and 8x rates are best for centering an object within the tele-
scope’s eyepiece.
Note that whenever any of the four buttons on the hand con-
troller are pressed, the LED in the center of the controller will
shine red; when the button is released, the LED will be green
again. Also, when the LED starts to blink at a constant rate, it’s
time to change the batteries in the battery pack.
