3. Remove the cover by lifting up while tilting the rear of the cover forward at the
same time.
4. Using a non-conducting flat blade tool, pry the firmware chip from its socket by
placing the non-conducting tool between the firmware chip and its mounting
socket.
5. After removing the existing firmware chip, position the new firmware chip in
the mounting socket. Ensure the alignment slots (on the firmware chip and the
socket) are aligned (see Figure 36). Then apply sufficient pressure to the chip to
seat it in the socket.
6. Replace the AXR-WAVES housing cover back on the housing and secure the
cover with the four screws removed in step 1.
WAV-PK Battery Pack Firmware
Perform the following to replace the WAV-PK firmware IC.
1. Remove the WAV-PK battery cover by pressing outward on each of the battery
cover release tabs while lifting upward and backward at the same time (see
Figure 29).
2. Grasp the battery and lift it from the battery compartment. Then, pull the bat-
tery clip from the battery.
3. Turn the WAV-PK upside down and remove the four screws (Figure 37) holding
the bottom cover to the top cover.
4. Remove the bottom cover by lifting up and forward at the same time (Figure 37),
as the arrow (
á) shows. This will allow the bottom cover to clear the Wakeup
button.
5. Lift the main circuit board and the connector board from the WAV-PK housing
and turn them over (when the bottom cover is first removed, you are looking at
the bottom of the main circuit board and it must be flipped).
6. Refer to Figure 37 for component location, then disconnect the antenna from the
receiver/transmitter module, allowing unrestricted access to the firmware chip.
7. Using a non-conducting, flat-blade tool, pry the firmware chip from the strip
sockets. See arrow (
á) for the position and direction placement for your non-
conducting pry tool.
Caution
Ground yourself before touch-
ing anything within the AXR-
WAVES housing. If your body
retains any static electrical
charge and you touch the cir-
cuit board, severe damage will
occur to the components
mounted on the circuit board.
Caution
Use extreme care when prying
the firmware chip from its strip
sockets. The firmware chip sits
on top of another integrated
circuit and you may damage
the lower circuit or destroy
circuit board traces if care is
not used.
