The cockpit-mounted remote switch assembly is comprised of an ELT status LED and control
switch, which allows an operator to monitor ELT status and manually turn on the ELT (i.e.,
activating) for testing and resetting (i.e., deactivating) the ELT. See "Figure 3. Cockpit Remote
Switch".
NOTE: The ELT CANNOT be disarmed or disabled from the cockpit. Cockpit operation is
limited to deactivating or manually activating the ELT.

The buzzer (i.e., horn) provides an audible alert when the ELT is active. See "Figure 4.
Buzzer".

The battery pack for the C406-N Series ELT consists of four “D” size lithium manganese
dioxide cells connected in series. In an effort to increase the safety of the battery pack, a
number of features were designed into the battery pack. To prevent the cells from being
charged, diodes are connected across each cell and fuses are connected to the output. See
"Figure 5. Battery Pack Assembly".
