• Remote Power channels on/off
• Duty cycle of stepping motor when at rest (power consumption)
• Step Rate of motor when running (motor speed), StepSize, and Microsteps/count (coarseness of
movement)
• StepSize (number of microsteps per count)
How do two buttons control all these functions? In general, one starts and then moves through the Manual
Menu using the IN button (on the left). The beeper tells you which menu item you are on. At each menu
item, the OUT button (on the right) is used to change the setting of the menu item. The power LED tells
you what your setting is for the menu item. You leave the Manual Menu using the IN button.

Note on Manual Menu items. Although five settings of each of the configuration items are available in the
manual menu, you can also set intermediate levels using the computer configuration screen. If at some
point you have set a configuration value for a menu item (via the RFCP configuration) that is different from
those available manually, when you get to that menu item the LED will flash SIX times. If you push the
OUT button to select a different value for that menu item, you will begin to cycle through and must select
one of the five available values listed in the table. You can NOT return to the original setting except by
using the RFCP configuration screen. Thus, if you are using the buttons locally only to operate the remote
power module, be sure not to use the OUT button once you are past menu item #4.
Remote Power. You can operate the remote power module either locally or remotely.
To operate the remote power module locally (i.e., when you are in the observatory without a computer
running RFCP), you need to change the status of the RoboFocus into the manual power mode and then
select the desired action. You will do this by manipulating the two motion buttons as described above. A
beeper will provide audible feedback, while the power indicator lights on the remote power module and the
LED on the RoboFocus will tell you whether each channel is off or on.
To enter the manual power mode, hold both buttons down until the RoboFocus begins to beep. Let up on
the buttons: you will then hear a single beep every 3-4 seconds showing that you are in Channel 1. If you
want to change the state of Channel 1, press the second (OUT) button until you hear multiple beeps, then
let it up. The Channel will have changed state, and RoboFocus will again repeat the regular single beep.
The RoboFocus LED will tell you whether the power is on or off on that channel. You can change the state
of Channel 1 again, if you like. When you are ready to move to Channel 2, hold the left button down until
you hear a double beep, then let up. You will now hear a regular two beep cycle. You can change the state
of Channel 2, or proceed to Channel 3 or Channel 4 as desired.
