Batteries 9
MiniTT1, Canon or Nikon
Note proper polarity
The MiniTT1 saves batteries by
automatically entering an extremely low
power state when the camera enters sleep
mode, or if not on a camera and TEST is not
pressed for 10 seconds.
Install a fresh CR2450 coin cell battery into
the MiniTT1 Transmitter. Make sure to note
proper polarity. When the battery is in the
radio, you should be able to see the + sign.
Life expectancy varies based on usage
profile, as well as camera and flash models.
When using a CR2450:
• Canon MiniTT1 = 100’s of
hours/thousands of triggers
• Nikon MiniTT1 = approximately 30
hours of camera awake time
Basic Trigger Mode consumes the coin cell
battery more quickly and is not recommended when using the MiniTT1 for Nikon on a Nikon camera, or when using
the MiniTT1 for Canon on a Canon camera.
Low temperature can significantly affect coin cell performance. Always use fresh batteries in cold temperatures.
Make sure to read the Safety Warnings about temperature.
MiniTT1 and FlexTT5 Status LED

Look at the normal Status LED blink to determine battery level, or use the PocketWizard Utility.
LED Blink
1 Green blink = More than 50% remaining
2 Amber blinks = Warning – less than 50% remaining
3 Red blinks = Less than 25% remaining – change immediately
These battery levels are tuned for alkaline batteries in the FlexTT5 and a standard Lithium coin cell in the MiniTT1.
Other battery chemistries can work, but their battery level may not be reported accurately.
Please note: The LED battery level blinks are based on the discharge curve and voltages of standard Alkaline
batteries. Those are the most common and most predictable. Rechargeables have slightly different voltages, very
different discharge curves, and, considering the different chemistries and aging of the batteries, are less predictable
from the LED's perspective. It would be nearly impossible for us to make an LED battery level blink that
accommodated all chemistries and aging of rechargeables.
You can still use your rechargeable batteries, but you need to build your own mental map of how they perform over
time. If your rechargeables last 20 hours, then plan accordingly. If they blink amber when fully charged, then work
with that information. If they only last a few hours when the LED blinks red, then use that information. The radios
will reliably measure the voltages, but the LED colors and blinks will have different meanings for your batteries
relative to alkalines.
