5. Install counterweight(s)
: iEQ45 comes with two 5kg
counterweights. Use one or both of them for your
particular OTA (Optical Tube Assembly). An optional
CW shaft extension or additional CW is available for
purchase at www.ioptron.com.
6. Attach OTA to mount and balance
: After attaching
an OTA and accessories to the mount, the iEQ45
must be balanced to ensure minimum stress on the
mount (such as gears and motors inside). There are
four (4) Clutch Screws on both DEC and R.A. axes.
Please refer to the full manual for balance
procedures/tips.
7. Connect cables
: Attach one end of an RJ-11 cable
into the socket on the side of the DEC unit and the
other end into the DEC socket located on RA unit.
Use another RJ-11 cable to connect the hand
controller to the HBX socket located on the RA unit.
Plug 12V DC power supply into the POWER socket
on RA unit. The red LED will be on when the power
switch is turned on.
8. Setup Controller:
The time and site information of
the observation location needs to be entered for
precise GOTO.
Turn the mount power on. Wait for controller lights on.
Press the MENU button. Move the cursor to “Set Up
Controller” and press ENTER. Select “Set Up Time
& Site” and press ENTER.

Enter the date and check if it is Daylight Saving Time
using arrow keys and number keys. Enter your time
zone (add or subtract 60 minutes per time zone) by
entering minutes “behind” UT or “ahead of” UT, such
as:
• Boston is 300 minutes “behind” UT
• Los Angeles is 480 minutes “behind” UT
• Rome is 60 minutes “ahead of” UT
• Sydney is 600 minutes “ahead of” UT
All the time zones in North America are “behind” UT.
You may also find your observation longitude and
latitude coordinate from your GPS navigator, a GPS
capable cell phone or from internet. “W/E” means
western/eastern hemisphere; “N/S” means
northern/southern hemisphere; “d” means degree; “m”
means minute; and “s” means second. Use number
keys and arrow keys to enter your location information.
Move the cursor to the end of the screen to select
Northern or Southern Hemisphere.
