NOTICE
NOTICE
Before shipping, the factory attaches an insulated sheet
to the battery contacts. Remove this sheet before use.
A slight current flows inside the GB-500 even when power is
off. Therefore, if storing the GB-500 for a long time with the
batteries installed, the batteries will run down and the GB-500
may become inoperable. Remove the batteries if storing the
GB-500 for two weeks or more.
Figure 2-1 on page 2-2 illustrate steps one through three for
inserting the BT-60Q batteries.
