Checking the number of the program

Edit Mode

Ø Make sure you are in the program, you want to edit.

Ø Press and hold RESET and turn on the SWITCH. Continue to hold RESET. Red light will blink out the number of the program.

Ø Continue to hold RESET and press SELECT once. Release both buttons. You are now editing the first command of the program. The time for that command is cleared to zero and a new time can be entered by pressing the buttons as follows.

Ø Press SELECT and RESET buttons to enter time. Each press of SELECT button adds one time interval; RESET button adds ten time intervals. Each interval is 0.02sec for the first command in F1B mode. Look in the table below for other intervals.

Ø To enter zero time do not press SELECT and RESET buttons. Go directly to the next step.

Ø Press LAUNCH. The time is stored in memory now. Press and hold RESET and pressSELECT two times. Release both buttons. You are now editing the second command of the program. The time for that command is cleared to zero and a new time can be entered by pressing the buttons as follows.

Ø Press SELECT and RESET buttons to enter time. Each press of SELECT button adds one time interval; RESET button adds ten time intervals. Each interval is 0.1 sec for the second command in F1B mode. Look in the table below for other intervals.

Ø Press LAUNCH. The time is stored in memory now.

Ø Continue the same way for third, fourth and fifth command. If you skip the command, its value remains the same it was.

Ø When you done, turn off the SWITCH.

Ø To edit another program, first select another program. Than enter times as described above.

Ø I may suggest that the program number 3 is used for 3 minute flight; program number 5 is for 5 minute flight etc. Program number 11 is factory preset for the short times to check the Timer operation and Cam positions.

Ø You may edit any command of any program this way. . The Timer operates in an additive manner, that is, the time of any command is its own time plus the accumulative time of previous commands. A change of time of a middle event will affect those events that follow.

Ø As with mechanical timer it is recommended to check the Timer operation with the stopwatch. This way you can make sure that you program the timer the way you desire.

Cam Ready Position Setting

Ø Press and hold SELECT and turn on the SWITCH. Release SELECT. The red light is blinking rapidly.

Ø The Cam can be re-positioned by using the RESET and SELECT buttons. Each press of theRESET button will move the Cam forward .9 degrees and each press of the SELECT button will move it backward .9 deg. Gear slack must be taken into account during repositioning as it may appear that the Cam is not moving as it takes up gear slack. However the true position change will show on the next usage of the timer.

Ø Press LAUNCH. The new Cam position is stored in memory now.

Ø Turn off the SWITCH.

Ø Press LAUNCH. The new Step value is stored in memory now

Ø Turn off the SWITCH

To return to factory default settings

Ø There is a secondary backup memory that contains all the factory settings. However, the cam ready position and rotational Step settings are always saved to both memories each time they are changed.
