to the platform or try to hold the remote controller in a different position. The nominal range is
around 3-5 meters / 10-15 feet.
Note: every remote controller has unique ID, so only it’s original
platform controller will rece
ive it’s transmissions. This way more than one platform can be
used in the same time.
2.5.5 Reaching a Limit Switch
Before the platform reaches any of the limit switches, it will sound a short beep in every
seconds. This is a final countdown, and you have 10 seconds left to stop the photographing
before initialization starts. After 10 seconds the platform goes to the home position, then
restarts the tracking automatically. If the DEC axis reaches the limit switch, only this axis will
reset, the RA axis continues the tracking. If RA limit switch is reached, then both axis will return
to home position.
The object of interest will be lost during homeing, so you have to find it again.

3. Changing the Operation Latitude
TEPP systems works between 33-62 latitudes on both hemispheres. You get the platform
preset according to your location. If you stay within ±2 degrees around the default latitude, it’s
not necessary to change the settings. In this case it’s perfectly enough to compansate the
difference by the setting the holding legs and tilt the whole platform. (Note: the spirit level is
cannot be used this time)
If you want to use the TEPP on a different latitude, you can change the platform settings, and
reassemble it to the desired latitude.
To use the system on 33 or 62 degrees, just setup 35
and 60 degrees respectively.
Before start the assembly, always make sure that the platform is not loaded and not
powered!
Required tools:
3 mm and 4 mm Hex keys
7 mm and 8 mm Wrench
Loosen the screws on each side, and adjust the red arrows to the desired value, then tight
them very well! 1 degree accuracy during selection of the latitude is enough, since further
finetuning will be possible if you make precision pole finding (eg. adjust the lenght of the
legs, or use the Scheiner method).
