Selecting the Right Size Tube
The Hybrid includes 3 different size tubes: Small, Medium and Large. Place the
Hybrid over your ear, with the medium tube attached. If the tube is too short, the
Hybrid’s back end will be up and the front end will be down. In this case, see Step
4 to change to the large, 3B tube. If the tube is too long, the Hybrid’s back end
will be too low and the front end will be too high. In this case, see Step 4 to
change to the small 1B tube. Right tubes are labeled in red print, left tubes in blue.
Too Short Correct Too Long
Battery Insertion
The Hybrid uses a standard size #13 battery.
• To insert, remove adhesive sticker. Any moisture on the battery surface should be
wiped off prior to insertion. Open the battery door and insert the battery.
• To remove the battery, open the battery door and lift the battery out of the battery door.
Low Battery Indicator: When your battery is low you will hear five beeps indicating
that it is time to change your battery.
Helpful Hint: It is recommended that you leave your battery door open when not
using your instruments. This will prolong the life of your batteries.
Caution: Keep batteries out of reach of children or anyone who may accidentally
swallow them. Never put batteries in your mouth for any reason. Do not store batteries
in medication containers or where they may possible by mistaken for medication and
accidentally swallowed. Never attempt to recharge non-rechargeable batteries.
