The Gamma Gear requires six AA 1.5 V Alkaline batteries – four in the right hand and two in the left. Use a Philips cross-head screwdriver to install them.
The battery compartments for your Gamma Gear are located on the bottom of each hand, just below the thumb. Unscrew the two battery compartment screws on each hand and remove the battery compartment covers. Insert four AA batteries in the right hand and two in the left hand, making sure the positive and negative ends are facing in the correct direction as indicated in the battery compartment. Replace the battery compartment covers and tighten the screws.
Your Gamma Gear may stop working before the batteries are completely dead. Always have a spare set of batteries ready in case of emergency. A good recruit is always prepared for any eventuality in battle.
As well, if you use disposable batteries and they no longer power the Gamma Gear, don't throw them away! Try them in a different household device – they may have some power left!
The Avengers Labs recommends that you ask an adult for help when removing and installing batteries.
