I have used the Chrony brand of chronometers for quite a few years but have never used the option to by the printer they offered as I thought it is wiser to spend
the money on powder and primers + bullets. So after a little investigating around I found out that the port for the printer on the chrony can be used for other
purposes. So for under $15.00 you can do this.
Remote control
The simple remote for the F1 and Alpha allows you to step through some statistics and the shot memory using the F1's built in display. This is otherwise only available using the Function button on the Ballistic printer.
Parts list:
3.5 mm Stereo jack (1/8th”)
Pushbutton switch
2 core cable for spst , 3 core for 2 switches. 2 switches see below. If you have a remote head, than its the same length as the head.
Small box
How to:
Mount the switch(s) in the box, or may be self enclosed
Solder the cable across the two connectors.
Solder the other end to the Sleeve and Ring of the audio plug.

If you build this keep the box you mount the switch in fairly small then it fits nicely inside the chrony
Usage.
(Taken from the manual)
The push button on the Remote Control is the equivalent of the FU button (or Function button) on the Chrony Printer.
The F-1 Chrony will provide you with summary data such as Hi, Lo, Average velocities and the total number of shots fire. Plus: Extreme Spread, Standard Deviation as well as numbered shots and retrieval of individual shot velocities.
1. Deleting Single Shot:
Press & release the button repeatedly until the desired shot number is displayed (NOT the velocity). Press & hold the button until display flashes. Release button immediately. The Chrony will automatically adjust the statistics.
2. Starting a new String:
Turn your Chrony OFF and the ON again. Or, (if you don’t want to get up) press & release the FU button until -Hi- is displayed. Hold the button in until the display changes to -CL-, then release the button. -Clr- is now displayed. Press & release the button until the display changes to -CLS-, then press & hold button in until the display flashes. Release button immediately.
3. Retrieve Information:
Anytime you wish, you may view the data you have produced. To do this, simply press the button, identify the information you are about to receive, release button and read the information. Repeat this process for each piece if information shown below.
Code:
What you see on press the button What it means is what you see on release
-Sn-
String number Will always be #1 with the F-1 Chrony;
-Lo-
Lowest velocity, velocity of the slowest shot
-Hi-
Highest velocity, velocity of the fastest shot
-Av-
Average velocity, Average velocity of all shots
-ES-
Extreme Spread, Hi velocity minus Lo velocity
-Sd-
Standard Deviation, Standard deviation of string of shots
-To-
Total number of shots recorded since Chrony was turned on. The number of shots fired.
-10-
# of last shot fired, velocity of 10th shot
-9-
# of next to last shot fired, velocity of 9th shot etc., etc., repeat until all the shots have been shown, then -[ ]- appears. This means the end of the data and, that you are ready to shoot again. If you press the button again, you start the viewing cycle over again. Simply pressing and releasing the button takes you from one piece of data to the next.. If you wish at any time during the viewing process to return to the working mode, stop pressing the button and wait 15 seconds. It returns to the working mode by itself. Sometimes, if you hold the button down for more than two seconds at a time, the unit will go into a sub-menu. Wait 15 seconds, it will return to normal by itself. When you think that you may have done something wrong, take your hands off, and it will go back to normal by itself.
