Unlike more modern Peterson strobes, legacy models such as the Peterson 400, 420, 450 and 700 do require occasional calibration.

If you require service, please open a support ticket and return the tuner for repair.

1. Begin from a powered off state
2. Press and hold both outer plus ( + ) and minus ( - ) buttons until the device powers on
3. Press and release both outer + and - minus buttons to show TST in the lower right corner of the display
4. Press and release both outer + and - buttons once again to show NEW in the lower right corner of the display
5. Press and hold the middle Menu/Power button to power off the device
6. Press and hold the middle Menu/Power button to power on the device

Your StroboClip HD will now be set to factory default settings.

Adjust your instrument until the pattern is as close to still as possible. Strobe displays are 'real-time' and extremely precise. They require very fine tuning adjustments to stop the display because the frequency/pitch of any instrument is never totally stable.

You'll quickly learn to read the display, make the most precise adjustments and appreciate the high resolution that only a Peterson provides.

Chrome needs access to /dev/hidraw*, so either set "chmod a+rw /dev/hidraw*" or start chrome as root with the --no-sandbox option

*Some Ubuntu based distros do not allow running Chrome as root with the --no-sandbox option enabled. -Running as root without --no-sandbox is not supported. See https://crbug.com/638180. You can however run Chromium as a normal user and invoke that option.

Some users have reprted a fix by adding a new udev rule as follows: KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev", ATTRS{idVendor}=="2368", ATTRS{idProduct}=="*SEE BELOW"

* Some Peterson products operate in two different modes with individual product id's for firmware update operations. Multiple rules may need to be created. Here is the list of Peterson USB product ID's

idProduct =

Stomp Classic = 8002
StroboPLUS HD = 0003
StroboPLUS HD Firmware Mode = 8003
StroboClip HD = 8004
StroboStomp HD = 8005
StroboPLUS HDC = 0006
StroboPLUS HDC Firmware Mode = 8006

If there is trouble connecting or reconnecting as a product is switching modes, ex: StroboPLUS HDC product id 0006 to StroboPLUS HDC Firmware Mode 8006 run the command:

"sudo chmod a+rw /dev/hidraw*"

This command will solve any "waiting on user input" or if the update button in Peterson Connect is unresponsive. The command may need to be executed more than once.

Cases are available for the AutoStrobe™ line, the StroboClip HD and the StroboPLUS HD/HDC.

• StroboStomp Mini
• StroboPLUS HDC
• StroboClip HD
• StroboStomp HD

A restart of your computer will usually solve this issue.

After your computer powers off, restart your computer, plug in your tuner, and the USB drivers should install automatically.

Peterson Connect will not function in Safari. Custom Configuration, Sweetener Design, and Tempo Map designer will function in Safari, but Safari does not support webHID therefore data transfer to your device is not possible.
