(5) Reinstall the front case, making sure the sensor, horn gasket and sensor
gasket are properly seated.
(6) Replace the four screws.
When switching ON the device for the first time and after a battery replacement
the device will initialize the battery. During a battery initialisation, BATT INIT is
shown on the display followed by a sequence of LED illuminations and activa-
tion of the vibration motor. The device then continues the start-up as described
in section 3.4.
4.3 Replacing the Sensor
(1) Verify that the device is turned off.
(2) Remove the four case screws and remove the front case to expose the
sensor (located near the top of the device, near the alarm lights Fig. 14).
(3) Gently lift out and properly discard the sensor.
(4) Install the new sensor in the sockets on the PC board (it can only be
installed one way). Press the sensor firmly in place against the board.
(5) Reinstall the front case, making sure the sensor, horn gasket, and
sensor gasket are properly seated.
CAUTION
Do not over-tighten the screws; otherwise, the case may be damaged.
CAUTION
After replacing the battery or if the device was without power for some time, it
is necessary to set time and date again using the MSA Link software.
CAUTION
Before handling the PC board, ensure you are properly grounded; otherwise,
static charges from your body could damage the electronics. Such damage is
not covered by the warranty. Grounding straps and kits are available from
electronics suppliers.
WARNING
The new replacement sensor must be the same part number and type as the
one being replaced; otherwise, improper operation will result.
