Using the NiMH Battery Pack
To use a NiMH battery pack with the System 824, unscrew
the battery cover at the back of the System 824 by hand or
using a flat blade screwdriver. If alkaline batteries were pre-
viously used, remove the Terminal Assembly (Figure 1-8).
Insert the battery pack so that the positive terminal is ori-
ented down and to the right, as shown in Figure 1-7.

next generation batteries
which will give you 40% more run
time.
To use alkaline batteries, remove the battery cover, and if
installed, remove depleted alkaline batteries (or NiMH bat-
tery pack). If not already installed, insert a battery Terminal
Assembly (AM814.06) so that it is positioned as shown in
Figure 1-8. Insert three AA alkaline batteries so that polari-
ties match those indicated in the battery compartment and
secure the battery cover.
