Jermaine,
Yea, what Woketman says...

Here's one specific to my Hotspot, as an example. It is especially important to use when you are being constantly interupted/distracted at flying events and air shows. It measures about 1.5" x 2.5" (#6 Arial Font size) and is hinged with tape underneath the canopy area in the fuse so I can stow it out of the way as needed.
