Tool Requirements
These are the tools you need to remove and replace the cardiograph's
subassemblies:
7/32-inch nut driver
Small flat-bladed screwdriver
TlO and T15 Torx drivers (or Torx driver kit, HP part number
5181-1933)
Long-nose pliers (recommended, but not necessary)

vi?
The directions in this chapter generally assume you are facing the
front of the cardiograph as you work. Thus, for example, the "left
side of the cardiograph" means "the left side as you face the front of
the unit."
The Battery
Removing the Battery
Caution
This section explains how to remove and replace the battery. These
procedures apply to all units.
To remove the battery:
To prevent the loss of data (including the configuration and software)
stored in system memory, the cardiograph must be connected to AC
r7
with the AC switch turned on when the battery is removed.
If you are servicing an M1700A or M1701A PageWriter, store the
configured software on disk as described in "Configuration Files" in
Chapter 2. If you are servicing an M1702A PageWriter, print a copy
of the cardiograph configuration (see Chapter 2). Doing this will help
you reconfigure the PageWriter when power is reapplied.
. Connect the power cord to the cardiograph, then plug the cord
into an AC outlet.
2. Turn on the AC switch on the back of the cardiograph and check
that the AC indicator on the front panel is lit.
3. Open the battery compartment by loosening the two captive
thumbscrews on the back of the cardiograph as shown in
Figure 7-l (the figure shows the M1700A).
