Connecting Internal or External Power
The 824 is shipped with a NiMH
battery pack installed. The System 824 can be powered using a 3.6 V NiMH
battery pack, individual alkaline or NiMH cells, or an AC
power supply adapter. For specifications on operating time
under battery power, see “Battery Operating Time (full
capacity, continuous operation, reference environmental
conditions, individual cells may vary in performance)” on
page -C-6. Below we will discuss how to install and use
each.
Using the NiMH Battery Pack
To use a NiMH battery pack (BAT010) with the System 824,
unscrew the battery cover at the back of the System 824 by
hand or using a flat blade screwdriver. If individual cell
batteries were previously used, remove the Terminal
Assembly (Figure 1-8). Insert the battery pack so that the
positive terminal is oriented down and to the right, as shown
in Figure 1-7.

page 3-3. For detailed information
on charging NiMH batteries, refer to
the section "Power Settings" on page

If power is supplied with the AC
Power adapter, the NiMH or alkaline
batteries do not require removal and
will power the unit if the AC power
adapter fails. Without AC power or
batteries installed, memory loss will
occur.
