Case Relay Manual
The Case Relay External Power System (EPS) lets you power your
camera continually with an external battery pack, providing
peace of mind knowing you have an uninterrupted power source
for your camera.
If you’re shooting and power gets low on the primary external
battery power bank, simply swap out the power bank. Your
camera will not turn off. Power will continue to ow to your camera
with the Case Relay EPS internal 1200mAh battery. Utilizing a wall
outlet or external power banks, you could theoretically shoot
forever with uninterrupted consistent power.

camera at www.TetherTools.com/Relay then click on the Shop by
