As the name suggests, the Spy Pen is a must-have tool for any aspiring spy. This battery-operated device looks like a pen, but has other features such as a built-in alarm, telescope and flashlight. Like any other battery-operated device, the power will drain with regular use. Fortunately, the Spy Pen was designed to be sturdy, but easy to use, so the batteries can be removed with little difficulty.
Remove the screw from the pen with a screwdriver. The screw is located just beneath the rubber grip pad.
Grasp the rubber grip with one hand and the tip of the pen with your other hand. Twist your hands in opposite directions to remove the tip.
Flip the pen upside down to remove the old batteries.
Put the replacement batteries in the pen. The positive ends of the batteries should go in first.
Twist the pen cap back on the pen body and secure it in place with the screw.
