EMG MODULE INSTALLATION AND

REMOVAL

A. Tools and Equipment Required

#1 Phillips Screwdriver
Flat Blade Screwdriver

B. sEMG Installation

NOTE:

If installing or replacing an sEMG Module
on a Therapy System with a Channel 3/4
Electrotherapy Module or Battery Module
already installed, and the sEMG functions
are desired for Channels 1 and 2, it will be
necessary to remove the module from the
system.

Refer to 6.2, part C

for instructions.

If replacing or installing an sEMG Module
to a Therapy System with a Channel 3/4
Electrotherapy Module, and it is desired that
sEMG function be available to Channels 3 and 4,
it will not be necessary to remove the module
as it will be installed to the Module.
The sEMG Module can only be installed on the
Therapy System and Channel 3/4 Electrotherapy
Module. This allows a maximum of two sEMG
modules on a four channel Electrotherapy or
Combination Therapy System. An sEMG Module
cannot be installed on the NiMH Battery.
Only two channels of sEMG can be used at
any given time even if the Therapy System is
equipped with two sEMG Modules.

Disconnect Power Cord from the power
source and turn system over on its face.

NOTE:

When turning over Therapy System onto its
face, place a clean, soft cloth under the lens
to prevent scratching or lens damage.
Using a Flat Blade Screwdriver, carefully
remove the four breakout tabs on the System
bottom.

See Figure 6.12.

NOTE:

Twist the Screwdriver to break tabs free.
Carefully remove tabs so as not to cause any
damage to the PC Board Contacts below
the tabs. If installing on the Channel 3/4
Electrotherapy Module, remove tabs from the
Module in the same manner.

DISCONNECT THE SYSTEM FROM THE POWER
SOURCE (OUTLET OR REMOVE BATTERY MODULE IF
INSTALLED) BEFORE ATTEMPTING ANY MAINTENANCE,
INSTALLATION, REMOVAL, OR REPLACEMENT
PROCEDURES TO PREVENT ELECTRICAL SHOCK AND
POSSIBLE DAMAGE TO SYSTEM.

Be careful to not damage the contacts of the sEMG
Module, Therapy System, or Module Stim Board
contacts.
