BATTERY REPLACEMENT INSTRUCTIONS
The Send iT level requires one CR1/3N lithium battery, which is a 3 volt battery. Use high quality batteries for the longest power life.
To remove the battery, pull the cover off the main body of the level. Do not pull on the knob. It stays attached to the main body while the cover slides off. Replace battery and slide the cover back onto the main body until it snaps over the o-ring.
To ensure your next battery replacement goes well, take extra precautions to face the fold of the Long Range Arms sticker facing up. This should make your next battery replacement easier by giving you a tab to pull the battery out. Please refer the image below.
Be sure to face the positive end of the battery toward the knob at the end of your Send-it level
