Test Procedure 1) Place the ELT in a secure screen room to prevent radiation of signals on emergency frequencies. 2) Apply 12 volts DC (from a power supply or external battery) to the test terminals at the bottom of the unit. See figure 6 for polarity. CAUTION: Do not attempt to test the ELT by immersing it in water. - Page 9 Test Procedure 1) Place test fixture on non-metallic table or platform in secure screen room to prevent radiation of signals on emergency frequencies.

Once water activation occurs, the battery chemistry changes and cannot be reused. Return the unit to ACR for battery replacement and factory rebuild. At the battery expiration date, the ELT with battery may be returned to ACR for inspection and recertification. Units accepted under recertification will be labeled with a new 5 year battery expiration date and may be returned to service. -
