Section 2: Pump Setup and Programming
In order to install or replace the batteries, be sure the pump is
Stopped. Then, follow these steps:
1. Push down and hold the arrow button while sliding the
door off.
2. Remove the used batteries. Pulling on the end of the battery
strap will make battery removal easier.
3. Install the new batteries in the compartment, making sure
the battery strap is positioned correctly under the batteries.
NOTE:
• Be sure to match the polarity markings of the new batteries
(+ and –) with those labeled in the battery compartment. If
you put the batteries in backwards, the display panel will be
blank, and you will not hear a beep.
