• Ensure that the module is set up for the correct voltage.
Tip: check the label on
the main circuit board
cover.
• Remove the existing module by undoing the four screws and gently pulling
the module loose from the connector.

compatible with a Gaitronics enclosure. With a 16 pin connector the
harness part no. is P5541 or with 24 pin connector part no. is P5542. If the
module was ordered with the appropriate harness it will already be installed.
If the harness is not already installed refer to the instructions accompanying
the harness kit for installation on the module.
• Set the speaker mute jumper on the circuit board of the replacement
module to the desired position.
